Ability

Portalpalooza

Launch a ball at the current target that explodes for @MagicDamage@ (%i:scaleAP%) magic damage, and colors the area for @DOTDuration@ seconds, dealing @DOTDamage@ (%i:scaleAP%) magic damage over the duration. If the ball lands in an area that is already colored, it will bounce to a new location within 2-hexes before exploding.
