Having used an actual crowbar in home renovation/demolition, I can say that the reality of a crowbar on something like chest would leave little to no chance of breaking what is inside it. Since the crowbar is designed to pry- through leverage- bashing and breaking is very remote. The current crowbar on a chest system seems somewhat detrimental to use. I have had critical fails which broke inside objects on rolls from 1-8. I understand perfectly that the goal is to have a full party go everywhere and for that party to contain a rogue who has lock picking skills. But the reality of the game is also this, sometimes partying up just isn't feasible. Sometimes there isn't enough rogue characters of equivocal level for each party that has formed that a character actually knows- without resorting to the other server cultures of sending shouts- "hey we need a level 5 rogue with a 17 in lock pick". I think there can be some compromise on the crowbar/chest system, and still keep much of the goal of "pushing toward" a party up mentality.
1: I think the crowbar should only break items inside a chest on a roll of 1 or 2.
2: and this has happened to me in real life albeit without the dice rolls, on a roll of 3-6 a damage on the user roll should take place. a roll of 3, 1d8. roll of 4 1d6, roll of 5, 1d4, and roll of 6 1d2+1. a nice message with the damage could take place, a " you just sliced open your hand"- or "you just whacked yourself in the head hard" cuts from use could have a wounding effect for a few minutes, hits in the head could cause confusion or daze for a few.
3: Crowbars should become apart of the smithing craft.
4: a copper crowbar could then lower the fail chance by 1, bronze by 2, iron, by 3, steel by 4.
5 the weight of the crowbar is 3 times what a normal one actually weighs. I have a 4 foot destruction bar made of tempered steel that only weighs 4 pounds. the in game one is 13 pounds.
