However, this behaviour is characteristic of respawn or the triggered arrival of monsters. The best example I have of this is courtesy of Tennessee Ernie Ford's Guide to Enroth (MM6) - (no relation to the singer, AFAIK).GoblinWatch Keep: Just Dropping In?
Lovely to see goblins stuck in the ceiling.
Find the room with four chests on its East wall.
Opening the second chest from left will generate 2-5 Goblin Shamans in the room, but we want to do this in turn-based mode.
Face the 2nd chest and press enter to start TBM.
Press the spacebar to open the chest.
Turn (while still in TBM) to find a few of the goblins stuck in the ceiling.
