Ulfrun's Descent

(TAP) Voruna drops to all fours and prepares 5 brutal charges that lock onto enemies. Ulfrun, the most powerful wolf, leads the attack as Voruna dashes toward her target. The pack deals increased damage to targets and nearby enemies that are inflicted by Status Effects. Lethal attacks double the damage of Voruna's remaining charges. (HOLD) Ulfrun guards Voruna. If Voruna falls during this time, Ulfrun dies in her place.

Introduced in Update 32.2 (2022-11-30)

Cast Changes

  1. Modifies Ulfrun's Descent with: Ulfrun's Descent Augment: During Ulfrun’s attack, enemies that die from Slash Status within 20m restore Voruna’s charges.
  2. Rank up the augment to unlock the full effect values.
  3. Costs a mod slot (and capacity) — only equip it when the change matters for your loop.

Worth the Slot?

  1. Worth it when the augment’s change is central to how you play Voruna.
  2. Skip it if the base Ulfrun's Descent already does what you need and you’d rather keep the slot for survivability or strength.

Tips & Tricks

  • Read the battlefield first — cast Ulfrun's Descent when it actually solves the room, not on cooldown habit.
  • Pair Ulfrun's Descent with movement and energy economy so you’re not stranded after a big spend.
  • On Steel Path, confirm whether Ulfrun's Descent still carries without strip, Viral, or a squad buff.
  • If you never press 4, it’s the first Helminth candidate on Voruna.
