The item of choice is the Omenak Mask, specifically for the dark angel set bonus.
The stats are based around other existing masks, especially Ocean. It is made to be more useful on Monk than Ocean, but still have incentive to use Ocean on something like a Jester or EV due to the higher Hero Damage/Ability Two. The tower stats are decent for when you need to build auras in the heat of battle as well.
This item is a homage to the weapon used for a low stat Great Old One challenge. Item name, upgrades and quality are a reference to the original Obunga's Lament (the Mischief Maker used in the challenge). Description and forged name is a reference the original 'Obunga' Great Old One challenge. Mana value is a reference to the HP value of Great Old One on one player scaling.
