Shade of Aran seems to be missing his pre-nerf Conflag ability:

"Conflagration - Deals 8000 fire damage over 10 sec to the affected player, and a smaller amount of damage to nearby players. Conflagged players are disoriented and cannot use any spells or abilities."

""Dragon's Breath"

(sometimes called 'Conflagration') Aran will cast this spell shortly after the "Flame Wreath" debuff wares off. It should only hit one player within melee range of Aran and it is important to heal that person as, besides the immediate damage they will take, they will receive a debuff which will deal large amounts of fire damage very quickly. It can be removed via Divine Shield, Ice Block, and Cloak of Shadows."

Seems to do 1k~ fire damage to the people around the conflagged target.
