Bondable Sinstone

Bondable Sinstone is a toy that can be looted from the Taskmaster's Trove at the Feeders' Thicket in southeastern Revendreth. When used, it summons Sinny, a tiny sinstone golem who floats above the caster's right shoulder. He takes the role of a "shoulder devil" while active, tempting the caster with questionable advice and insight.

If this toy is used at the same time as the Bondable Val'kyr Diadem, Sinny and Angelis will argue.
