If a PC had his brain "eaten" by an Intellect Devourer and then goes into an antimagic field...?


Rotten DM
You want to know the best question to ask someone if you think an ID has eaten their brains?
Ask this question. 'WHAT IS YOUR FAVORITE ICE CREAM?" If they don't give a flavor they are IDed. Because Intellect Devourers hate brain freeze!

The brain was magically consumed and is gone, so the field does nothing for that. The devourer magically teleported into the empty space, but that magic is also already gone, so the field would do nothing for that. About the only thing that would happen is that the devourer couldn't use any magical abilities while in the cell, but it wouldn't be forced out.
