Blasphemy is a support gem that converts supported curse gems into an aura.

Skill functions and interactions

  • The supported curse is applied as an aura around the player, affected by both their curse and aura radius increases. It is not affected by Aura Effect modifiers, as these only apply to friendly auras.[1]
  • Curses applied via Blasphemy count towards the active curse limit, preventing application via casting if it were to exceed the caster's active curse limit.
  • When Blasphemy auras from multiple sources exceed the curse limit, the curses that affect the enemy is determined by the closest source.
  • Level 1 Blasphemy supporting a level 1 curse has the same base radius as the curse, which is .[2]
  • Blasphemy has a special interaction with mana multipliers as it changes the way of a curse being cast. Casting a curse will reserve 35% of maximum mana and behaves exactly like an aura as reduced mana reservation will apply. The wording on Blasphemy is "Mana Reservation Override".
