Breaking Inanimate Objects
Simply make an Athletics test, since this skill covers brute force, modified by the difficulty of the task at hand. In the case of the door, there is no modification if the door is a standard door made of wood, but it becomes hard if it’s reinforced, and even impossible if it is made of stone. If the wood is rotten the Referee may make the roll easy or even not require a test. Some objects may not be broken, unless the character is under the effects of magic that plausibly increases their strength to the level where breaking the object is possible.
