- Each blast of arcane power strikes its target more quickly than the last.
Arcane Blast is a level 10 Arcane mage spell that deals direct arcane damage, with increasing damage levels and mana costs with each stack of Arcane Charge. With careful management, the mage can use this spell to trade off damage per mana versus damage per second.
Tips and tactics
The mana cost increase will run you out of mana VERY quickly. While chargeless Arcane Blast is fairly efficient in terms of DPM, a single Arcane Charge stack will double the mana cost and make it on par with the primary spells of the other specs. Under most circumstances, spamming this spell with 4 stacks of Arcane Charge is very inefficient and unsustainable. The efficacy is further diminished by reducing the damage bonus from as your mana is depleted.
The best use of Arcane Blast is to only cast it when you are above 90% mana, then alternate between (no mana cost) and Arcane Blast until all charges of Arcane Missiles are consumed. Once you can no longer cast Arcane Missiles, dump the stacks of Arcane Charge with .
Arcane Blast is like (and unlike , , and Arcane Missiles) in that it doesn't have a projectile animation. This makes the mage a bit less obvious in PvP combat as Arcane Blast won't leave a brilliant pointer back to the caster. Also, it's pretty hard to keep the debuff going as you'll hardly have time to sit around spamming 2.25 second casts (luckily for you).
