Was fighting the crocolisks or whatever they are on the beach - 2 of my companions were standing on a ridge and I was on the sand, but still decently far from them. I throw a smoke grenade and they all get blinded, then we're immediately taken out of combat as the crocolisks wander off (still blinded) but start regenerating their health.
I know reptiles don't have the best memories, but surely they should still realize we were trying to kill them...
