• Bane of the Stricken — almost mandatory gem for Greater Rift progression, as it is designed to whittle down the scaling health numbers of monsters with a percentage-based increase on successive attacks.
• Boon of the Hoarder — synergizing with other farming mainstays like Avarice Band Avarice Band and Goldwrap Goldwrap, this gem will not only keep you rich, but also sped up and safe during normal rift farming.
• Bane of the Powerful — the speedfarm counterpart to Bane of the Stricken Bane of the Stricken, Bane of the Powerful Bane of the Powerful offers a solid overall damage and survivability increase as long as your killing speed does not fall behind the timer of the gem.
