Void Reaver

The Void Reaver is a new robotic-crustacean Monster added in the Hidden Realms Update, who can appear on Rallypoint Delta, Siren's Call, and Sky Meadow after the first Loop.

Void Reaver corpses can be observed both around the Void Fields and the Null portal in the Bazaar Between Time, with the latter ones being impaled by spikes of what appears to be purple glass.

Environments

 * Rallypoint Delta (only after Looping)
 * Siren's Call (only after Looping)
 * Sky Meadow (only after Looping)

Nullifier Artillery
The Void Reaver attacks by means of artillery, where it lay several Nullifier Bombs around the target that explode in a small area after a 1 second delay.

These bombs inflict the stacking Nullify Stack debuff on hit. When this stacks 3 times, the victim is given the Nullified debuff which reduces their Movement Speed to 0.

This skill has a Proc Coefficient of 1.0.

Nullifier Implosion
Upon death, a delayed implosion will instantly kill anything caught in it, even the Void Reaver's allies. Despite the instant kill, the implosion does not do damage.

If the player has a Dio's Best Friend, they will still be revived regardless.

Dying to this explosion yields a unique death message: "You have been detained, await your sentence at the end of time." If someone else in your multiplayer game gets killed by the explosion the death message for everyone else is " has vanished without a trace."

Trivia

 * The Void Reaver is the only Monster that doesn't appear (within the regular Environments) prior to Looping.
