I'm not sure this is supposed to be a literal drum. It might just be a conjugation of the verb to drum. The item says "drumS of the beast".
Way back in the day i mean before the baz and my bard would sell in the ec tunnel 1st torch ;P i had drums of the beast and would give people enduring breath (instant cast) they would stop and look around haha but the graphic wasnt a drum but a tangerine look pretty cool although a few yrs back i got it and it looked liked a basic drum so i sold it was sad. Course no pictures. Always gave Sergeant Slate a bad time my favorite npc mob.
