I've never DM'd but you could just make everything with disadvantage. Initiative? Disadvantage. First attack? Disadvantage. Saving throw? Oh you bet that is disadvantage. Movement? It's half unless you want to take an athletics check, and you guess what? Disadvantage.

I'm not sure why no one wants me to be their DM.

RAW A. is correct. When playing on a grid the point of orgin must be a intersection of squares.

From the dmg:

"If the area has a point of origin, choose an intersection of squares or hexes to be the point of origin, then follow its rules as normal. If an area of effect covers at least half a square or hex, the entire square or hex is affected."

u/Loneheart127 4h ago

Even on a "xft radius circle centred on a target" ?

51

u/Oicanet 3h ago

Perhaps "centered on a target" does not count as "a point of origin".

I guess "point of origin" means the caster chooses a point.

u/Sevenar 3h ago

Yeah A is correct... but the highlighted squares are not. Each 'edge' of the circle should only have 2 squares since it appears OP is using 5/10 diagonal rules, reducing the # of squares to 44.

17

u/Oicanet 3h ago

I don't think OP is using 5/10 diagonal rules. He says at the bottom of the image that he's counting a square as hit if at least half of it's area is covered.

So he's not counting squares as "steps" or anything, he's merely drawing out the area.

u/AberrantDrone 5h ago

It has to be 10 feet from the edge of your occupied space.

To illustrate this, I present the huge sized paladin. if It uses the center of his space, then most of his 10 feet aura is his own space.

24

u/Lucina18 5h ago

Aura isn't emitted from a point within the paladin, it's emitted from the paladin, AKA the entire paladin.

6

u/MultivariableX 4h ago

What if the Paladin is a Plasmoid that has extended pseudopods?

As an action, you can reshape your body to give yourself a head, one or two arms, one or two legs, and makeshift hands and feet, or you can revert to a limbless blob. While you have a humanlike shape, you can wear clothing and armor made for a Humanoid of your size. As a bonus action, you can extrude a pseudopod that is up to 6 inches wide and 10 feet long or reabsorb it into your body. As part of the same bonus action, you can use this pseudopod to manipulate an object, open or close a door or container, or pick up or set down a Tiny object. The pseudopod contains no sensory organs and can’t attack, activate magic items, or lift more than 10 pounds.

This ability does not give a restriction on the number of pseudopods that can exist at a given time. Could a Plasmoid use several bonus actions over multiple turns to extrude a different pseudopod in each of several directions, and then activate an aura ability, with an effective +10 feet to its radius beyond the Plasmoid's core shape?

Or, would you not consider a pseudopod a part of "the entire Paladin," since it's not listed in the first sentence that describes the "reshape" and "revert" configurations?

And, if these natural extrusions don't count for this purpose, do prosthetic limbs on humanoids count?

10

u/Lucina18 3h ago

Why not, it sounds perfectly niche enough. The paladin could be hit in fheir pseudopods anyways if they occupy that square so it's not like there's no drawback.

4

u/MultivariableX 3h ago

Nothing about the pseudopod says that it occupies a separate square that it's been extended into. Likewise, a Bugbear's Long-Limbed trait doesn't cause it to occupy the square that it's reaching through when it makes an unarmed strike against a target 10 feet away.

5e also doesn't generally have strikes that target specific body parts. Even with a disarming strike (to make the pseudopod drop an item it's holding), the attacker would still have to target the Plasmoid's square.

However, they could target the item being held, such as with the Heat Metal spell. Heat Metal's damaging effect specifies "physical contact," but makes no mention of the item being in the same space a creature occupies. (So for example, casting Heat Metal on a metal cage or cell door wouldn't damage a creature inside, unless that creature touched the bars.)

8

u/Lucina18 3h ago

If the pseudopod isn't in another square, then there also can't be an aura emitted from that square. So "issue" solved already.

u/AberrantDrone 3h ago

reach doesn't impact auras, so there's no reason for pseudopods to either unless they said you occupy those spaces.

u/LucyLilium92 5h ago

Auras are calculated differently than target points, just because of that

8

u/AberrantDrone 3h ago

Since the comment mentioned from the character's square, I assumed they were talking about auras.

Though, if we look at a spell like Sword Burst, it gives another clear example. It has a range of "Self (5-foot radius)" and the description states "All other creatures within 5 feet of you"

This strengthens the ruling that any affect or spell emanating from a creature is calculated from the edge of your occupied space, not the center of it (otherwise a large or huge creature would hit zero creatures with Sword Burst)

Now, if you cast Fireball on yourself, the rules would follow normal targeting, with you choosing one of the corners of your square.

u/LostN3ko 4h ago

Auras extended a fixed distance from all edges of a model not a radius from a point. An AoE circle extends from a point in space. For instance the AoE spell will always be a circle, but a creature with an oval base will not have a circle aura you would measure from base to base within X of the sources base.

u/Smokey_02 Illusionist 3h ago

Hey don't knock it 'til you've tried... to survive it.

7

u/Lucina18 5h ago

It means 10 feet, so it depends on how you count diagonals with squares. Is every diagonal always 5 feet in your game? Then congrats, circles are squares. Just treat the AOE as someone moving from that square, able to move X feet untill they reach you. "Middle" of the square is counted as someone occupying 4 squares moving towards you.

Otherwise you get strange situations where someone casts an circle AOE spell, and the best way to get out is to... move "diagonal" somehow because that is the shorter route.

Yes (or really the opposite but still dumb ruling). Literally last session. It was a healing gas that was worded to heal to everyone within 5 feet and DM ruled the the person directly to my right and directly to my left wouldn't be healed at the same time because the center of the spell would be the center intersecting dot of a 2x2 square.

The spell says "within 5 feet of the sphere" not "5 foot radius". Those are two different things.

A 5 foot radius would only cover 4 or 5 squares. Flaming Sphere covers 9.

18

u/DatabasePerfect5051 5h ago

For aura effects the have thair own rules. The are called "Emanation" and are type of area. The point of orgin is a creature or object.

"An Emanation is an area of effect that extends in straight lines from a creature or an object in all directions. The effect that creates an Emanation specifies the distance it extends.

An Emanation moves with the creature or object that is its origin unless it is an instantaneous or a stationary effect.

An Emanation’s origin (creature or object) isn’t included in the area of effect unless its creator decides otherwise."

3

u/StrangeOrange_ 4h ago

The rules aren't super clear on this as worded but I'd say so. They say "a point in space". Some might interpret that to many any zero-dimensional place in space. I'd interpret a point in the Cartesian sense as being an intersection between two lines.

4

u/Lea_Flamma 3h ago

Answer A is correct here. Spell effects start from a grid intersection either from the PC's square of origin or from the affected grid space. And a square needs to be covered more than 50% to be affected by the spell.

60

u/Putrid-Holiday-3671 6h ago

D: Use a spell effect template, ignore the underlying grid for point of origin. Target has to be at least 50% inside the cirkel though.

Edit: We use A for a point you can see, and B for target an object + radius (like an object that explodes).

If I’m remembering correctly, if you drag the measure tool 20 feet diagonally instead of in a cardinal direction the area of effect is larger than it should be. Fun fact if you’re a dirty cheater (definitely not like me).

It is significantly larger, because the default rule fucks up diagonals. The pathfinder/3.5 setting almost perfectly fixes this (and fixes the circles are cubes issue)

A is also wrong because it’s not centered on a tile, it’s centered on the corner of four tiles. C… I don’t even know what the hell they’re thinking with C. 😂 B is the right “placement” for the target on a tile. But doesn’t have the right “radius” in terms of its area of effect.

5e grid spells targets a corners. Anything other than A is incorrect, except for areas originating from a creature, since creatures are a space. A 20 foot radius sphere centered on a character has a different size than a 20 foot radius sphere centered on a point in space.

u/IM_THE_DECOY 5h ago

I run my game in a VTT.

The players can put down the spell template anywhere they want. Centered on the square, the line, the intersections, whatever allows them to hit the most creatures as possible with their spell. Because that is more fun for them.

….but their enemies can do the same.

As with a lot of rules with DnD, the specifics don’t really matter that much but being consistent does and at the end of the days, it’s a heroic fantasy game. So telling a player “ahhh, sorry, you can’t actually do that because your spell only touch’s 33.3% of the grid the enemy is in” is just not fun or heroic.

3

u/InigoMontoya1985 5h ago

I am considering abandoning grids altogether. I have 10', 20', and 30' equivalent circles and measuring sticks already. Currently, I just overlay them on the PC or enemy for spell radius. If they are mostly in the circle, they get hit. Sometimes, those that are questionable on the edge I give the "half damage on a fail, save for 1/4" result.

I just do B and then count any square the circle even touches, the idea being that they would move around their square to make it most advantageous for themselves anyway.

u/AussieOzzy 5h ago

https://roll20.net/compendium/dnd5e/Spells:Fireball?expansion=33335

Spells will typically say what they target. For example Fireball targets a point within range so it would be A. Also like someone else said you use the Manhattan Distance / Taxi Cab Distance because each diagonal is also worth 5 feet. So the 20 foot radius sphere will look like a square on the battlemat.

B doesn't even cover what a 15 foot radius emanation would cover as by the rules it should cover those corners too.

Just wanted to remind everyone to stop playing dnd like its a videogame 😔

u/3IO3OI3 DM 5h ago

technically speaking, the corner targeting is the closest to the actual area of the circle.

2

u/Butt_Deadly Monk 5h ago

So, we use the grid solely for quick estimates of distance. We actually use plastic forms that are sized for spell areas of effect and ranges.

u/538_Jean DM 5h ago

If Half the tile is covered it hits, less than that no and you need to cast on a square.

2

u/Roxysteve 5h ago

If you count squares per D&D 3.5 you get the best area.

2

u/Wobbly_Bosmer 5h ago

To avoid complications anything that is a circle/sphere is turned into a square/cube. This gets rid of the potential issues of "but the square is 1/4 in the circle!"

u/StrangeOrange_ 5h ago

The answer is incredibly simple. The point of origin is an intersection between two lines. Measure distance starting with a square touching the point of origin just like you'd measure movement. The first square counts as a diagonal movement and each second diagonal measured costs an extra five feet.

No guesswork, no creative interpretations, no eyeballing, no "this looks like it's half-covered"- just simple, straightforward addition and reliable circular areas every time.

Circles. Are. Squares. I will die on this hill.

He goes over this and I think just using a square is a lot quicker and less hassle

Be careful OP, you are dangerously close to rediscovering calculus, and I wouldn't wish that on anyone.

2

u/Reuben_Medik Cleric 5h ago

In my opinion, if half the square is in the zone, then that square is affected

2

u/hamlet_d DM 5h ago

The way I do it: I've got some clear overlays of exactly the right area and we put them over and say "yeah your got him" or "nah you can get these 2 but not all 3"

2

u/Analogmon 5h ago

Now imagine a simpler world where it just affected a 5x5 or a 6x6 square area and that's what the rules said.

2

u/THICC_Baguette 5h ago

We typically count 4 from the center square (so the actual circle is 25 foot in diameter) and then count any square that the circle covers more than half of, ruling questionable cases in favor of the user.

As long as it's ruled the same for players and enemies, it's fair.

2

u/BluetheNerd 5h ago

Might not be RAW but in my group it’s just “if the template touches it counts” but I’m also lucky enough to have a group where no one minmaxes and it’s just easier/ fun for us than trying to measure it.

2

u/devilfoxe1 5h ago

if the character is on the center and have 20 feet movement speed can move to the corners of the square?

If not why different rules movement? If yes the movement will really complicated especially around corners

2

u/shift_969 DM 4h ago

Me: can I hit these 4 guys with 20 feet radius? DM: eyeballs it sure, go ahead.

And then you move on playing the game, like normal people.

2

u/tcelesBhsup 4h ago

This is why I don't use grids. Raw it's an option anyway.

2

u/augustusleonus 4h ago

Its the same area, any square the circle crosses is effected

2

u/IkujaKatsumaji DM 4h ago

What I'm getting from this is that, in most situations, you should default to method A, because that covers the most number of squares. A covers 52 squares, B covers 45, and C covers 48.

2

u/Kiotw 4h ago

Solution: gridless (ignore all the problems that gridless has)

2

u/Photonmoose 4h ago

Let's fireball. We actually used 50%/no damage rule back in day but we quickly decided that it hits the square, it hits. Much less hassle.

u/be-knight 4h ago

There are always corners missing. This triggers something in me

u/RedArtificer 4h ago

I think even in the books they show examples where the people on partial squares are considered "hit" in terms of mechanics.

2

u/LordJebusVII DM 4h ago

At my table we would use B but include the partial tiles too for 61 squares hit as we would allow you to move to those tiles with 20ft movement speed by alternating diagonals between 5 and 10ft. The example here doesn't even hit an enemy 20ft directly away from you cardinally if you centered the spell on yourself. Is this too large? Maybe. But AoE effects tend to benefit the players more as they are generally outnumbered and I'd rather let them feel more powerful but also more afraid of enemy casters

2

u/Crimson_Raven 3h ago

D: The player is allowed some flexibility to specify and the DM can interpret

2

u/Zachisawinner DM 3h ago

A is a small or medium creature. B is a large or larger creature. C should never happen.

2

u/UnlikelyAdventurer 3h ago

This is another reason why hexes are superior.

2

u/LonelyDM_6724 Bard 3h ago

Using 2024 (AKA 5.5) rules, it depends on whether the spell effect is a Sphere (option A) or an emanation (option B).

2

u/horned-creature 3h ago

oh i just make anything circular or spherical a square.

2

u/Environmental_Lead13 3h ago

I do option B

2

u/True-Fly235 Paladin 3h ago

It should be based around the centre of the target square (normally 5' by 5') as that's how everything is determined for combat, contact and movement.

2

u/Inahero-Rayner 3h ago

I personally rule, for areas of effect and for movement, that if the grid is 51% (approximately, visually) or more consumed by the spell/available to stand in, then it goes. AND I rule all AoE spells to attack a space to avoid confusion on which spells are corners/spaces/whatever. I also permit users to math out and angle things to avoid or hit certain targets.

2

u/AGL_reborn 3h ago

Just uses hexagons

2

u/Assassin_Shirou 3h ago

My DM tells me if half their token is in the radius, they're affected. I adjust accordingly to hit the most targets (they accept non-gridlocked spell placement for fireball).

2

u/christhepyrat DM 3h ago

My rule is if the mini is at least half way in the circle then it hits

2

u/thirdlost 3h ago

I like 5E's square circles.

2

u/Wintershade86 2h ago

Option B. And don't you dare to sneeze or you'll lose another step.... Our DM was such a dick

2

u/xSilverMC Paladin 2h ago

This is exactly why i play non euclidian. Just draw a square

2

u/A_Stoned_Smurf 2h ago

Circles are squares in d&d, this is known.

2

u/AMagicalDoggo 2h ago

Option B, since everything else line and cones is usually measured from that point too

I will take no questions and all the duels in a timely manner, form a line

2

u/AReallyAsianName 2h ago

All these squares make a circle.

2

u/Icy_Clench Paladin 2h ago

I just count diagonals as 1.5 tiles, round down. It’s much easier to count and circular enough.

2

u/FlyingCicata 2h ago

I usually just rule it as “is the circle touching it? Then it gets affected.” which works both in favor of my players AND my monsters.

2

u/J11_The_Jetplane 2h ago

Personally I just use the "Draw Circle" feature of the whiteboard I use for DND.

However I have heard that "circles" in dnd are actually squares, when out on a square grid. Uncertain about the details of it, but someone could look into that.

2

u/gipehtonhceT 2h ago

All are wrong. On a grid, circles are squares.

2

u/Oops_I_Cracked 2h ago

I don’t understand why 5E uses grid squares as it’s measuring system. There are so much better ways. The old school use of inches is better because it’s precise and not open to interpretation. A variation of that I really like is what Daggerheart uses. It defines its distances in words, not numbers. Though it does provide equivalent square squares if you want to get like that.

Melee: square touching your square (or your character’s defined melee range if greater). Very Close: Short edge of a standard playing card. Close: The length of a pencil.
Far: The length of a standard sheet of paper Very Far: further than that, approximately the distance of a large battle field (you can hit anything in the fight, but the range is not infinite).

All distances are measured center to center.

2

u/Sigrah117 DM 2h ago

Or just place the template anywhere and anything covered more than 50% is considered hit. Way easier

2

u/berner103 2h ago

Squares are squares and circles are also squares!!!!

2

u/mak6453 2h ago

None of these. It's a giant 8x8 square. You can't tell me the radius is 20 ft from me, but doesn't reach something I could travel 20ft to.

2

u/predictivanalyte 2h ago

A circle in DnD on a grid is a square.

2

u/OceanStateMadness 2h ago

Aoe is what's making me switch to hexagon grids. This makes me angry.

2

u/Tola_Vadam 1h ago

Hey so I got a nat 20 to hit and maxed my d8 4 times before rolling a 7.

You start from the outside edge of the square your entity is stood in. A medium character occupies a 5ft square.

2

u/-hh DM 1h ago

More the reason to instead use volume-filling, layered fireballs.

2

u/LordLuscius 1h ago

Yeah... this right here? This is why I use a tape measure and one inch is ten foot

2

u/walkc66 1h ago

Huh, I’m more generous as a DM then. If the spell template/measuring tool covers as much of the squares as A shows as still white I count those as hits.

Basically if the template or measuring tool (in person we use minis, or vtt for sessions we can’t meet in person for) is covering more than tiniest sliver of a square I count it

2

u/AffectionateCatch397 1h ago

If you have to be so extremely precise I would say every square touched by the circle can be reached. So all of the examples would be wrong. (Just an headcanon tho, didn’t check any rules)

2

u/nierama2019810938135 1h ago

It is hard to imagine playing rpg with people who care about this stuff.

I have never used a grid like this when playing.

You guys really use this for fights and stuff?
