This makes the Halcyon Seed a little bit more useful by spawning Aurelionite during the Final Boss. From my own experience he won't deal much damage to the boss but should prove useful as a distraction.

You can even allow the Final Boss to summon his own Aurelionite if he manages to steal a Halcyon Seed. This one the boss gets doesn't scale as quickly as normal.

You can configure which phase Aurelionite spawns on (it's phase 2 by default).

Known Issues

  • If Aurelionite happens to spawn where a player is they may fall through the floor.
  • The name of this mod makes no sense.
  • Mithrix will say his dialogue when his Aurelionite spawns despite the fact that it's on his side.

Change Log


  • Added configuration Seed Strength Multiplier to multiply the item's effect when spawning Aurelionite for this specific encounter. (Mainly so people can match it up with the buff from GoldenCoastPlus as this Aurelionite doesn't get the buffs)

  • Added configuration Player Health Mult to multiply Aurelionite's health for this specific encounter when it's on the player team.

  • Added configuration Player Damage Mult to multiply Aurelionite's damage for this specific encounter when it's on the player team.

  • Added configurations Other Health Mult and Other Damage Mult they do the same as the above but for when it's not on the player's team.

  • Now uses the ambient level instead of the old way Aurelionite's health and damage scaled.


  • Compatibility for Anniversary Update.
  • Added "Kill On Last Phase" to allow the player team's Aurelionite to stay during the item steal phase.
  • Mithrix's Aurelionite now gets less health and damage and is considered a boss. (This means Armor-Piercing Rounds will work on it.)


  • First public release.
