Provoke an immediate confrontation with your Kuva Lich or Sister of Parvos: an insult which cannot be ignored.—In-Game Description

The Requiem Ultimatum is a one-time use Gear item used to lure the user's Kuva Lich or Sisters of Parvos out of hiding.



Acquisition[]
A Requiem Ultimatum has a 25% chance to drop upon converting or vanquishing a Kuva Lich or Sister of Parvos. It will only drop for their Progenitor player.

Notes[]
Can only be used in Lich/Sister-controlled nodes.
They are not affected by an active Resource Booster.
It is best to use this in solo due to an issue where the item may spawn a teammate's Lich/Sister instead of yours.
