Best Farming Location: Gea Kul (Kehjistan)

Among all Helltide rotations, Gea Kul in Diablo 4 Items Kehjistan is regarded as the #1 farming spot for Baneful Hearts:

Two World Events close together → easy chaining
High density of Hellborne & Harbingers
Commander events spawn frequently
Open map design → quick visibility and movement between events

Key events to prioritize in Gea Kul:

1. Cultist Tornado Ambush → Spawns dozens of mobs quickly
2. Summoning Circle → Portal cultists drop multiple Cinders and have decent Heart rates

Note: Gea Kul only appears when Helltide rotates into Kehjistan, so monitor rotation timers.

Extra Tips for Baneful Heart Farming

Group Play: More players = faster clears, more Hearts per hour.
Max Movement Speed: Boots, amulets, and skills like Teleport or Dash speed up rotations.
Loot Filters: Hide junk items to reduce downtime.
Track Timers: Use community Helltide trackers to never waste a farming window.
Balanced Builds: Prioritize survivability - Helltide mobs hit hard, and cheap D4 materials losing Cinders on death wastes effort.
