Otherworldly beings are monsters found in the south-west of Zanaris, in a separate room south of the bank and the range.
They used to be popular monsters to kill due to their close proximity to a bank and relatively high chance of dropping dragon helms. However, because of the fall in price of the dragon helms and the frustrating and constant mini-random events in Zanaris, the Otherworldly beings are not commonly fought anymore.
Slayer masters give the following advice for this creature: "Otherworldly Beings are ethereal beings making them weak to ranged attacks."
Otherworldly beings received a graphical update along with Zanaris on 13 May2010. Prior to the graphical update, Otherworldly beings were apparently invisible beings, and hence appeared as floating Dark Wizard robes. However, after the update they now have visible body parts.
Their old examine text was: Is he invisible or just a set of floating clothing?
If a Zanaris random event is triggered which renders you temporarily unable to attack (like turning into a pig or a chicken, performing the Dance emote) and you are in combat with an Otherworldly being, the Otherworldly being continues to attack, hitting for no damage. You are unable to retaliate, however.
In Runescape Classic, Otherworldly beings dropped 2 coins each kill.
