quaking-vialThe Quaking Vial is used by the Blacksmith Haedrig Aemon to craft a 2-Handed Mace named Sunder.

The Quaking Vial drops off elite Mallet Lords in the Hell Rift Level 1 (Campaign Mode): Hammersmash and Sledge. Open a campaign mode map and choose Act IV: 2. The Light of Hope — Corrupt Growths Tier 1. Search for the Hell Rift portal by destroying the Corrupt Growth. Enter Hell Rift.

Sunder – 2-H Legendary Mace

A Persuader is required to craft this weapon. Flesh Render can be looted from the Weapon Racks in High Heavens. I found mine in Gardens of Hope 2nd Tier.
