Destonite
From Destoria Wiki
Destonite is the most powerful resource in the ecosystem that can be mined from settlement plots and islands owned by players. It can also be obtained through defeating powerful monsters and completing challenging quests. Destonite is extremely valuable and can be used to gain a serious advantage within Destoria. This resource can be just as valuable, if not more so, than XP and STORI tokens in the right situation.[1]
Destonite can be mined on plots.[2]
