Void Reaver

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

Skills & Behavior
The Void Reaver attacks by means of artillery. This attack applies a stacking debuff on hit. When this stacks 3 times, the victim is kept in place.
 * Void Artillery

This skill has no Proc Coefficient. 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.
 * Void Implosion

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 don't appear (within the regular Environments) prior to Looping.
 * The Overloading Worm can appear pre-loop, but are extremely unlikely to do so due to their high cost for Directors to spawn.
