Prismatic spray has to target multiple enemies?

[MarkVIIIMarc]

Reading it I think when you cast PS you get one ray for each target in range. Is that so?

I assume you need some line of sight also.

Every spell an NPC is gonna cast I'll be asking questions about it seems. A FAQ of sorts lol.

Kind of? The book says it's 8 rays, but it helps to think of the spray more like burning hands, except random sections (or areas if, you will) of the fire are different colors.

You spray out the spectrum (all 8 colors) into the 60 foot cone. Everyone within the cone needs to make a Dex save, or they get hit by at one of the seven effects (they get hit by two effects if the d8 lands on an 8). What is important to note, is that their positioning makes no difference of what color they get affected by, two people standing in a straight line could get hit by two different colors.

And yes, you do need line of sight :)

I hope this helps!

Why would you need line of sight? The spell seems to work like any other AoE spell.

If the target has total cover then it won't be affected by the spell, unless the spell specifies otherwise.

So if a target is hiding in a chest freezer or something like that they are not affected?

Consider shining a flashlight with a filter on it that is a rainbow color wheel. The head of the flashlight spins in a clockwise direction so the colors cover a different area at least 1 time in 6 seconds. Now you place, in the cone of the flashlight's beam, 3 people and a large pillar. 2 of the people are exposed, one person is hiding behind the pillar.

Using basic information from the world around us, light will normally not bend around an object, so this beam would hit 2 of the 3 people, and they would be hit by each of the colors of the color wheel.

Even if we use a liquid instead of a beam of light, the same would hold true. The spray would normally not bend around an object and 2 of the 3 people would be hit by the spray.

In both cases, the 2 that are hit by the spray/beam would be struck by 1 color initially, then the rest. Their saving throw would be based on that initial color that makes contact with them. The rest of the spray/beam would be disregarded as they have fulfilled the required saving throw, since the spell doesn't ask for a saving throw from each of the colors.

The problem is not people with cover, the question is 'does it hit invisible people?'. If it requires line of sight it would not, if it is a normal aoe it would still hit them. The spell requires no line of sight of any sort.

The spell does not require line of sight. But cover still affects against it how cover works against any area spell with a dex save. If you want to blast off a prismatic spray into open space and hope you hit an invisible enemy, you are free to do so, and it would be fully effective at that.

All spells need line of effect (unless they say otherwise). No spell needs line of sight, unless it says otherwise.

So yes, if an invisible person is in the AoE, he gets hit. Unless he has total cover, in which case his visibility is a moot point.
