Gameplay Adjustments

  • Beneficial buff priority system
  • Spell batching removed
    • The 400ms "spell batch" window has been reduced to 10ms.
    • This should cause most player abilities to behave in a more responsive way, with damage and healing applied to targets faster. Certain operations in the game now resolve faster, such as purchasing multiple quantities of items from vendors rapidly.
    • Paladin seals will now persist on the Paladin for a very short time after they're replaced by a different seal, so that "seal twisting" remains possible.


  • There is now no area of the raised platform in Heigan the Unclean's encounter space that is safe from Heigan's mana burn while Heigan himself is on the platform.
  • Fixed a few areas in the Heigan the Unclean encounter space where Plague Waves could overlap and deal double damage.
