OOC: It's not a trap door, it's a normal door. Sorry if I gave you a another impression.
IC: The door is very sturdy, and kicking in it's center or at the handle won't help, however, kicking the lowest hinges does work. After a few well placed kicks, the lowest hinge begins to budge. After two more it immediatly falls off. The middle hinge can be gotten of as well, if you slam it with a firm object, the bed spill for example. But you cannot reach the top hinge, not alone at least.
OOC: what are you guys looking for in the temple, exactly?
