I am running a campaign where my characters need to destroy a roughly cylindrical stone, about a foot in diameter and a couple feet tall, with a hardness of 7 and 28HP (14 before it is broken). Hardness seems to act like resistance in general, but I would have thought that stone would have even greater resistance to slashing or piercing damage, than to bludgeoning damage. Is there any support for this in the rules, or has anyone just done it anyway?
don't know if there is a specific rule for this, but in this situation i would just give that stone pillar some additional resistance to slashing and piercing using the normal restance rules. maybe resistance 5, so that stabbing it is really not gonna do anything ^^
But picks are piercing, and pretty famous for being used against rocks. Maybe we should just accept that if you hit something hard enough, it doesn't matter too much what you're hitting it with
