Thanks so much for the details!
Now I'm just wondering whether the time is even needed (like waiting 25s compared to 10s). I think all chests need a certain strength/intelligence/finesse level to be broken. However finesse or intelligence controls the chance of not breaking the objects inside the chest.

Thievery also controls your chance of being able to lockpick a door or chest. This chance is much higher considering lockpicks are rare and you don't get personality points very often.

Although the level needed to break the chests with strength is a lot lower than with finesse and intelligence since intelligence and finesse decrease the chances if the objects being broken.
This allows for every sort of character to be able to break into the chests along with drawbacks because at the moment intelligence is of no use so it makes strength and finesse more worth while but you also have the choice to not use strength and ect and use a much more reliable way but with limited use.
Finally the only items that can't break are unique items, even if it's not necessarily realistic for a certain item to break, unless it's important to the story or is an "unique" item, it should break. That's the price you have to pay.
