A brimstone ring is a ring created by combining three untradeable components — the hydra's eye, fang and heart — player's cannot receive a duplicate of these until obtaining the others. There are no requirements to equip and it provides the combined offensive and defensive stats of the un-imbued archers, berserker, warrior, seers, treasonous, and Tyrannical rings, along with a Passive effect that rivals the Seers ring (i) for best-in-slot Magic accuracy.
Brimstone rings cannot be imbued.
Passive effect[edit | edit source]
The ring has a passive effect when worn. Each time the player attacks using a spell or magical attack, even from a powered staff, there is a 25% chance that the target's defensive roll will be reduced by 10% for that single attack only. 
Changes[edit | edit source]

A notification regarding the Brimstone ring’s effect in PvP has been corrected.
|13 January 2019
On release, the ring had a chance to reduce the opponent's Magic level instead of ignoring its magic defence, which could be stacked to render NPCs' magical attacks ineffective. This was fixed soon after discovery, approximately 3 days after the item's release. 
Trivia[edit | edit source]
- The brimstone ring's design comes from the common depiction of the Ouroboros symbol of a serpent or dragon eating its own tail.
