Overview
- Access to Heart of the Island rocks requires level 70, Frostspire Expanse, and completing Raven quests 1–2 to unlock the red-door Raven Cave.
- Each rock has 32,500 HP and yields one roll, with a reported 1 in 54,321 chance for a Stolen Heart and a recommended 650+ mine-power pickaxe.
- Efficient runs rely on previewing ore by partial mining, abandoning bad rolls, alternating nearby rocks, and using private servers or rejoin cycles to refresh spawns.
- A safe AFK method traps mini demonic spiders in crystals so players can mine uninterrupted in the hazardous cave.
- The Stolen Heart is required for Raven Quest 3 to obtain the Berserker blueprint with specified spider kills, grants a lifesteal trait when used in forging, and can be pursued with luck boosts from potions, achievements, runes, races, events, and totems.
