Umbral Escalation

Thrax is the Escalation Boss for Umbral Escalation.

"How far do the Umbral Deeps go? It's hard to say. But if you ever find yourself at the edge of a dark and shimmering pool — be alert. This is where Thraxes are known to feed. These cunning Behemoths use portals to hunt, striking through rifts with razor-sharp forelimbs and emerging from void-space to dive onto prey. Luring one into the open may be your best bet, but even this plan demands caution. Untreated, a Thrax's corrupting influence can leave a Slayer so drained that they can barely lift a finger — much less a weapon."

The Thrax weapons use a Bond instead of a Unique Effect and have a Legendary ability.

Legendary Ability: Activating your Thrax weapon's legendary ability will deal Umbral damage to surrounding enemies, then teleport you into the sky. Target a landing spot and slam back to earth to dish out even more Umbral damage.
