'Glacial Spike' is a cost-free 'Zero Arcane Power' (0AP) signature spell, which means that it always gets 100% benefit from the damage bonus provided by Bastion of Will, a ring set that will be updated for patch 2.2. The following test build uses a tri-missile Glacial Spike (runed 'Magic Missile') as main attack, made possible through the use of a Mirrorball source.
