An Elder Crimson Drake - AE Ability
 

This mob in East Temple Veeshan (Halls of Testing), I'm unsure what the AE is called, but it is using some AE Fire ability. It has a non-classic graphic. It is using some 2006/2007 era spell graphic currently.

While your at it, the Red and White wurms spell graphics are swapped in some cases. For example, one of the Red wurm's fire AEs has a frost graphic.

The first issue is fixed. The second issue I'll check out tonight. I do know acid jet is supposed to be frost if it's being fasted by the correct mob.

Wave of Heat is cast by a couple different mobs in HoT. Even though it is a fire-based spell, it appeared as a frost aoe in classic. I guess frost can burn.
