This is a quick and dirty fix to make nsrr's Frost Invoker compatible with Razakai's Death Knight.

Having both the original Frost Invoker addon and this Frost InvokerC addon enabled at the same time will crash the game on character creation.

This is made for personal use.

Simply gives Arcane Blade access to the Water and Frost trees.

Adds the Frost Invoker, a mage subclass.

The Frost Invoker is a Cold-focused caster and unarmed fighter. Their primary stats are Magic and Dexterity.
