Soulshape (Night Fae)
Night Fae Fire Mages can use
Soulshape, a movement speed increase with a built-in teleport you can use every few seconds. This is an amazing mobility tool, but Fire already has reasonable mobility with
Blink/
Shimmer,
Scorch and
Frenetic Speed. More mobility for Fire Mages is always welcome, but definitely not a necessity.
Summon Steward (Kyrian)
Kyrian Fire Mages can use
Summon Steward to call a Steward to offer a
Phial of Serenity, which is a
Healthstone with a cleanse effect baked in. The Steward also can offer repairs, a talent swap and a
compliment for your friends.
Mages are already able to remove most debuffs with
Ice Block. Using
Phial of Serenity to remove a debuff instead of a heal that could save your life in a pinch is not advised, unless the debuff you are removing is worth dying to remove. Overall, this signature ability has some personality but isn't very impactful.
Door of Shadows (Venthyr)
Venthyr Fire Mages also get
Door of Shadows, a targeted teleport with a short cast time. The range of this spell is 35 yards, which is a little under the distance of two
Shimmers used back-to-back. Door of Shadows is very useful, so long as you can remember to cast it when it is available. One gripe I have about this spell is that it is not a true teleport. It cannot be used to bridge some gaps, returning the error "No Path Available" at times.
Fleshcraft (Necrolord)
Necrolord Fire Mages gain
Fleshcraft, an absorb shield for 20-50% of your total health. Since the cast time is 4 seconds long for this ability, it is best used out of combat or at times that you cannot cast a damaging ability.
Remember,
Blazing Barrier also provides an absorb shield for 20% of your total health and is instant cast.
