chest types - wood, iron, stone, silver, steel, deadric, and then reinforced and magically loked versions of each.
"Daedric weapons are made from raw ebony which has been refined using the craft and magical substances of the lesser minions of Oblivion. The process is not a pleasant one for the Daedra involved, and the weapons retain echoes of preternaturally prolonged suffering endured during manufacture. Daedric weapons are the most rare and expensive weapons known in Tamriel." - Garothmuk gro-MuzgubAnd shouldn′t the progression be wood - silver - iron - stone - steel - ebony ? As far as I know silver isn′t too tough either. For enchanted version there could be enchanted wood, silver, stone and steel, and then there could be enchanted ebony and maybe daedric in rare cases, maybe a single chest in the whole game since daedric is pretty rare and would better be used for making armor or weapons unless there was some major artifact someone needed to protect and was willing the use daedric to protect it.
As for everyone saying it would be overpowered or silly to be able to bash down doors and chests. Isn′t it also silly that everyone will wait for you to do your lockpicking minigame ? And you have to phase through certain doors into a different cell just as much using a unlocking spell or a lockpick as if you bashed it down. Also there would be a downside of weapons getting broken and creating a lot of noise. So what else do non magic and non thieving characters have to go through before they′re allowed to roleplay a pure warrior ? If we really want to restrict each other then let′s look at it this way, warriors don′t get to go through doors because they′re not so precise with a lockpick and in return thieves don′t get to be able to slice through the scales of a dragon because they spent all their time learning to be accurate and precise with their hands instead of building up muscle like the warriors.
In fact the only ones who seem to have an excuse to be able to do everything is mages, let′s all roll mages so that we don′t have to choose between slaying dragons and unlocking doors/chests.
Just my humble opinions.
