I'm curious if a creature is affected by a spell effect, if it is standing in a square right outside of the spell effect, but is attacking another creature standing right inside of the effect.
I have a few cases to discuss.
Wall of Fire is first. It has an emanation effect. If you are adjacent to a square that is just outside of the 20' of heat, and attack someone who is in the heat, do you take damage when you "reach in" to attack them in their square?
Glitterdust is the big culprit. If you are standing right outside of the glitterdust effect, which is an ongoing area, and attack someone inside of the area you are adjacent too, do you have to save vs. blindness? If you were invisible, and attack someone adjacent to you, inside of the area of effect, do you become visible?
Grease, I would assume that if you are adjacent to a character in the Grease spell, and attack them, you are not affected by the spell effect, because logic dictates that the grease effect is a plane on the ground (2d).
Bloodmist. If you attack an adjacent creature who is currently in the red algae cloud, are you entering the cloud and have to make a save?
I could give more examples, and am most interested in an official rule on this, preferably in one of the books.
I've always played that if you are attacking into an area of a spell effect, then that spell affects you as if you were positioned within the spell. Am I wrong?
