Boss information you can trace to a source

This is a selected patch-note index, not a complete boss roster or a tested walkthrough. Reviewed on September 17, 2026, using the full announcement text in Steam’s official news feed. The three names below appear in the August 29 update; that does not establish a total boss count or a mandatory route.

Dated changes for three named encounters

Name used in the announcementAugust 29: Week 1 updateSeptember 5: update
Droeg, the ConquererArena navigation, riposte alignment and physical hit reactions corrected; fire and snowfall effects revised, also improving performance.Explosion effects optimized; an issue that could misalign ripostes against Droeg due to Grisha Summons fixed.
Vrannic, the Grand IllusionistNew visual-effect trails for projectiles.No additional claim is made here.
Magdalena, the Lady of the WoodsIncorrect rotation during her charge fixed.No additional claim is made here.

Sources: August 29 announcement and September 5 announcement. These are dated changes, not a claim that either announcement is the latest patch. Empty coverage here does not mean an encounter received no other changes.

How these notes help when comparing guides

  • Droeg: the notes describe alignment and visual fixes. An older recording may show behavior since addressed by a patch. They do not establish a weakness, damage value or safe punish window.
  • Vrannic: a change to projectile trails supports a visual change only. It does not verify projectile tracking, clone health or a way to identify the real caster.
  • Magdalena: the charge-rotation fix is documented. It does not establish an optimal dodge direction or the timing of another attack.

Before following a route or combat demonstration, compare the recording date, game version and platform. A patch note confirms what its author reports changing; it is not our own gameplay test.

Correction to the previous guide

The previous page called five bosses confirmed and mandatory, then supplied locations, specific attack patterns, counterplay and rewards without traceable citations. Those unsupported guide claims are withdrawn. This includes the previously asserted routes and tactics for Gloombound Ritualist and Tar Golem; withdrawal is not proof that those names or encounters are false.

The patch references above support narrower statements for Droeg, Vrannic and Magdalena. They do not validate the old five-boss list, story order, hidden-boss coverage or upgrade-material drops.

What still needs direct evidence

A complete roster needs an identifiable game version and evidence for every entry. Mandatory versus optional fights need a demonstrated progression route. Strategy and reward claims need attributable gameplay or an explicit source that actually describes them. This page does not supply those missing results or promise a completion date.
