What is a dragon dagger

first off dragon is a step higher than rune and can only be equipted by members for instance hear is the strength lvls from weakest to most powerfull ok it starts with bronze then goes to iron then goes to steel then goes to mithril then goes to adamant then goes to rune then goes to dragon so all these have the same stuff just different material they are made out of so lets say you have a mithril square shield an adamant square shield is better so i think dragon dagger is simply the best dagger you can get except for poison dagger++ or something like that there may be better ones but as far as i know its the best
