A modifier that causes the affected spell(s) to gain a purple aura which constantly causes small amounts of damage (about 3-4 per game tick) to every enemy it touches.
- The damage amount of the aura cannot be increased without adding an additional one.
- This modifier synergizes very well with Triplicate Bolt due to the multiple projectiles it produces.
- It also works well with projectiles that don't dissipate for a while, such as Bouncing Burst, especially when paired with Homing which causes them to grind through most enemies in seconds.
- Works well with projectiles that don't disappear when hitting an enemy, such as Mist spells, usually combined with homing.
- Combine the effect with larger multicast modifier that spread projectiles wide, such as Quadruple Scatter Spell, to produce waves of aura projectiles.
