The animated object encounter in area 3 has TPKed two of my parties.
When I use the construct's trample ability, most PCs attempt to take the attack of opportunity rather than the reflex save to avoid damage, however the majority of them do not have the raw damage to overcome hardness 8. I make the animated object follow them throughout the dungeon if they attempt to run from it to the door in area 5. With one group this comically led to them all falling into the pit trap right behind the door.
Am I running this encounter correctly?
