Further to my previous idea, I'd like to suggest another tool, this time for destroyers.
Since Benefactors will be able to create locked chests, it is only appropriate that destroyers should be able to brutally open them somehow, and this is what this tool would do.
When a destroyer stumbles upon a locked chest, he can use the Lock Acid to melt the lock and get to the contents without having to bother with passwords.
Of course, this tool, like the one before, should be available from level 8 and up.
Also, in case Lock Acid is not good. Another name option would be: Plastique Explosive
