Arcane Explosion (often abbreviated as "AE") is level 6 mage point blank area of effect spell that deals arcane damage to all enemies within 10 yards of the caster and generates an Arcane Charge for Arcane mages. It is used most often to quickly kill multiple weak enemies.

Improvements

The 5 piece set bonus from the Netherwind Regalia set increase the radius of the spell by 25%, for a 12.5 yd radius.

Notes

Even though it is instant and has no cooldown, the effective casting frequency is limited by the global cooldown.

Tips and tactics

This spell is very popular. 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 also used by higher level characters for farming instances for friends or for other farming purposes.

Trivia
