Burning is applied before any other spell effects, thus providing excellent synergy for Steam, Virulence, Glowing Gaze, etc.
Only the target of the spell will suffer from Burning, making this less useful with Area of Effect spells such as Searing Flames.
Skills that shoot projectiles (such as Fireball) will actually start the burning process at the end of the casting, regardless of whether the projectile hits the target or not.
