A player cast phantasmal force and had an enemy believe a bunch of leeches were swarming his face and body. The NPC (human champion) spent two turns trying to get them off - basically taking damage and doing nothing of value. Then on his third turn I decided that the champion assumed they were a spell, not an illusion but that the Sorc had summoned leeches and put them on him, and he charged the Sorcerer in the hopes of breaking concentration to free himself from the leeches.

I think this was a fair reaction after 3 turns, the player was not happy though. The player thought I should have made a check instead to see if the illusion was real, but I didn't think he had any reason to think it wasnt real. Also the PC got 2 full turns of inaction out of it.

What do you think?
