Flame Shield

Flame Shield is a Defensive Fire spell used by  in Diablo IV.

In-game
This spell works similarly to Serenity in that it grants a complete immunity to all damage and effects for a very short time, and then recharges for quite some time. Likewise it can always be cast, even under Crowd Control (removing any) or while performing other actions.

It also deals a bit of periodic damage to enemies next to the Sorceress, but its short duration and low damage numbers make it completely ineffective as an offensive tool. Moreover, contrary to the tooltip, enemies damaged by the Flame Shield do not count as Burning.

Note that even though it removes any movement-impairing effects, it does NOT grant the ability to move through enemies unhindered, and as such, the Sorceress can be trapped by a large horde of enemies with little help from this spell.
