Zi Kieru

Zi Kieru (or just Zi for short) is a tiefling warlock whose patron is actually the Harbinger of Chaos. They wear jewelry that shifts colors as the god reacts. (note for self, that god is inri.)

One of their abilities is to call upon their god, which will give them a stat boost. A d4 must be rolled, and depending on the outcome it influences what stats get boosted/nerfed
