Macro Description

Arcane Mage cast sequence for Arcane Blast; it starts by casting Icy Veins and Arcane Power if they are available, pops both trinkets, then simply repeats Arcane Blast 4 times. At that point, you should either cast Arcane Barrage, or Missile Barrage if it's up, to avoid unnecessary and useless mana costs involved with stacked Arcane Blasts.
