The Granite Energy Storm is a moderately difficult Pre-Hardmode boss that must be fought underground. It can be considered a biome-specific boss for the Granite Cave biome.

Spawn[edit | edit source]

The Granite Energy Storm does not spawn on its own, and requires the player to summon it with an Unstable Core. It can only be summoned while the player is in the Granite Cave biome.

Behavior[edit | edit source]

When the Granite Energy Storm spawns, it will be circled by Coalesced Energy. These serve to block attacks from the player and influence the abilities of the primary core. Coalesced Energy will respawn after a set time.


  • The Granite Energy Storm attacks the player by floating around and pausing before charging the nearest player.
  • Once a Coalesced Energy is killed, it will become Encroaching Energy and home in on players, needing to be killed again.
  • After being lowered to 35% life, the Coalesced Energy will start to spin rapidly, increasing the chance to block attacks.
  • After losing 65% life, the Core will begin shooting energy balls at the players.

In Expert Mode.

  • If the core refreshes its Coalesced Energy, and some remain, they will be shot at nearby players for massive damage.
  • The energy ball attack will become rapid if no Coalesced Energy exist.
