Signora is the latest weekly boss in Genshin Impact, but she’s not available for players to take down right away. Our Genshin Impact Signora guide explains how to unlock Signora’s weekly trounce domain and defeat her in the boss fight.

Signora Archon Quest, Adventure Rank, and Resin

Signora’s trounce domain is on Narukami Island in Inazuma, but it’s only accessible after you finish the Archon Quest “Chapter 2: Act 3 - Omnipresence Over Mortals.” To access this quest, you need to complete the previous Archon Quest and be Adventure Rank 30 or higher.

As with other Trounce Domains, you can only claim rewards from Signora once a week. That normally costs 60 Resin, but if you’ve done less than three Trounce Domains in the current week, it only costs 30 Resin.

Signora boss fight

Signora has multiple forms.

Cryo attacks

At first, she’s Cryo-based, firing off icy attacks. If you get too cold, you’ll rapidly start losing health. Use fiery beacons in the corner to keep yourself from freezing.

She’ll then protect herself in a cocoon of ice. Use nearby fiery butterflies to amplify and add Pyro to your attacks. You can also break her shell using Pyro skills, but the butterflies deal more damage.

Pyro attacks

After this, Signora takes on her Pyro form, adopting the first phase’s opposite. The heat becomes unbearable. Use use icy beacons in the corner to keep your temps down and avoid losing health. Keep attacking her while keeping yourself, cool and she’ll go down quickly.

Signora drops

Signora can drop three different materials: Molten Moments, Hellfire Butterflies, or Ashen Hearts. These are for upgrading character abilities to high levels. As of writing this, Aloy and Raiden Shogun use Molten Moments. Kujou Sara uses Ashen Hearts.
