Skardyn's Grace V. Key to the endless chamber

[:1]Which one should I be using as feral DPS? does it matter which? I'm already using Fluid Death for my first trinket slot.

Skardyn's Grace

Vs.

Key to the Endless Chamber
Use Key to the Endless Chamber but reforge the hit.
Buy Unheeded Warning imo. Is currently better than most 372 trinkets.
