Posted this over at ENWorld, but I’ll think about it here: how much damage does an ogre cause if it falls on you?
Default damage is d4, which is what ANYTHING causes if it doesn’t already use another die.
Average damage is d8, which is what something that could be deadly causes, but you don’t happen to know what its damage die is.
An ogre probably carries a heavy weapon, which generally does d10 damage before perks/bonuses.
Given this, I’ll let you ponder for a while. By the way, if there’s an official answer, it’s “consult Rule Zero.”
