Wrack is a basic Magic ability with no level requirements. It is the exact equivalent of Ranged's Piercing Shot and Melee's Punish. It deals 18.8-94% ability damage or 37.6-188% ability damage if the target is stunned or bound.
The ability's small cooldown is useful for ability rotation when aiming to gain adrenaline. It is often useful to use Wrack in alternation with other abilities to avoid having most basics on cooldown, though in most scenarios it is not advisable to do so because of low dps output as a result.
The stun from Impact is too short for Wrack to deal its boosted damage, because Impact stuns the target for 1.2 seconds, shorter than the global cooldown of 1.8 seconds. Deep Impact gives enough time for the user to use Wrack once for its boosted damage. This ability's damage boost does not work on most bosses as the majority of them are stun-immune. Since it works against bound targets and not only stunned ones, targets bound with Ice spells will also trigger Wrack's extra damage, something that can be taken advatage of when using a lot of auto-attacks in conjunction with abilities, such as when doing 4taa rotations.
The Energising perk will make Wrack deal 20% less damage, but it will generate an additional 0.6% adrenaline per rank instead.
