Arcane Explosion

Arcane Explosion is a point blank area of effect spell that deals arcane damage to all enemies within 10 yards of the caster. It is used most often to quickly kill many weak enemies. It is often abbreviated as "AE".

Improvements
As with all mage spells capable of critical hits, Molten Fury and Shatter can increase the effective damage output of this spell.

Glyph of Arcane Explosion lowers the mana cost by 10%.

Tips and tactics
This spell is very popular (even more so when fully upgraded by talents). In instances especially, there are often groups of small non-elites either alone or surrounding a "leader" elite. Some instance groups bring a mage along solely to quickly deal with these pests. You won't mind being pigeonholed this way... it's both fun and a challenge to test your ability to stay alive.

This is used by higher level characters for farming instances for friends, and game friends usually. It can be used for other farming purposes as well.
