Wave of Denial is a powerskill which releases a shockwave that can protect the player.
Details[]
Special Effects:
Releases a shockwave outward from the player which deals 30 base damage to enemies it hits, knocking them back and stunning them for 0.8 seconds.
If an enemy hit by Wave of Denial hits a wall soon after getting knocked back, they take an additional 90+ base damage like Spartan Sandals.
Wave of Denial also returns enemy projectiles. However, most forms of ranged attacks just despawn and do nothing, while reflected explosives work normally.
Due to its negligible damage, the skill is best used defensively.
The Wave of Denial's damage is enough to kill smaller flying enemies like Bats and Kamikazes. That, coupled with its short cooldown, makes it an excellent choice for builds with limited vertical reach.
It is especially effective against the following enemies:
Bombers, as it can interrupt their flight and push them away.
Disgusting Worms, as it can easily remove all the bombs spawned by it.
Hammer, as it can easily kill the flies spawned by it and also return its spawned bombs.
Swarm Zombies, as it can be kept at bay while the skill takes out the flies and knock it away.
It can be abused near ledges to knock enemies to their deaths.
Since it attacks in all directions, Wave of Denial can be used to ward off projectiles from angles that are normally impossible to parry.
Bear in mind that while it repels projectiles, they are not registered as parries. It cannot trigger relevant mutations such as Spite or Blind Faith as a result.
In-game description makes no mention of its ability to repel enemy projectiles.
