You have wrested away part of Szass Tam's essence.

This item can be found in the Dungeon Master's Guide under the entry for Boon of High Magic.

Wondrous item, very rare (requires attunement) - This Helm of Brilliance appears as a monstrous batiri goblin mask is made of lacquered wood and its gems carved to resemble numerous unblinking eyes. When a gem is used, the surrounding wood closes around it like an eyelid. When found, the helm has 6 diamonds, 5 rubies, 17 fire opals, and 34 opals
