Piercing Void

Piercing Void is a Standard Chaos Arcana in Wizard of Legend

Description
Summon a field of void blades that rain down on foes!

Strategies
This spell's high "rate of fire" and duration can make it very useful to stagger enemies that have very short vulnerability windows such as Knight, Lancer, Master Sura's second phase, Crash Knight and Fleet Lancer. When an attack comes up, cast this spell on the location where the enemy will end his attack animation and the enemy will get hit when they finish their attack, during their vulnerability period, opening them to further punishment.

It is also a good CC spell to hold enemies in place in any room, but doesn't deal high amounts of damage by itself.
