GHOST3.ITM is an undroppable ring that grants immunities and various visual effects to certain creatures in the game, such as Aurumach Rilmani found on the Watcher's Keep Final Seal dungeon level.
This item provides 100% Magical damage resistance.
It also bestows a pulsing glow cosmetic appearance to the creature's sprite.
The item implements several IESDP Opcode 9 Color Glow Pulse effects, to make the creature look "unearthly" and partially intangible.
