Overview

Devil Hearts gate three upgrades: Awakened Devil EX (1), Jetstream (3) and the Devil Hunter title (5). You can hold at most 10 at a time, and the drop only counts if you extract.

How to obtain

Frostspire Bastion — hidden boss Awakened Devil (Nightmare/Endless)

Dungeon (Nightmare)

35.0%

Developer changelog (relayed)

Drop rate raised from 15% to 35% in a developer update; max 10 held; requires dungeon completion. The boss's per-run appearance rate is disputed: community guides say ~15%, while an official changelog set special boss rooms at 35% per run. Summon costs also vary by report (5 Celestial or 7 Frostspire Platinum Keys per official notes).

Used for

  • Awakened Devil EX evolution (1)
  • Jetstream unlock (3)
  • Devil Hunter title (5)

Farming recommendations

  • Loot only becomes permanent when you extract — a drop you don't extract is worth nothing.
  • Use the Farm Planner with this item's rate to budget runs and time realistically.
  • Rates are bound to their mode and difficulty — check the source context before comparing.
