Magic Crasher uses your MATK and ATK to deal a physical attack based on the element of your weapon on one target by consuming 8 SP. As a normal physical attack, the inflicted damage is affected by various conditions such as the accuracy of the caster, the defense of the target, monster size, and monster cards in caster's equipped weapon. On iRO, this skill is known as Stave Crasher despite not having anything to do with staves.
