While transformed into a Werewolf Behemoth (whether in Stone Garden or in the Infinite Archive), you cannot change the skills of your Companion due to being unable to change skills with a special ability bar active.
When attempting to change your Companion's skills in this state, you'll receive the error message stating "You cannot change skills while your character has special abilities." but you'll see your Companion's skill bar change visually. However, this does not actually change the Companion's skills — they will continue to cast the original skill in that slot. You can visually fix their skill bar by summoning them again.
Some workarounds if you happen to be stuck in Werewolf Behemoth form but need to change your Companion's skills:
- Infinite Archive: If you happen to grab the Bestial Transformation Verse at the end of a stage in the Infinite Archive (or get it via a consumable Offensive Verse at the beginning of a stage) but need to change your Companion's abilities for the encounter, you can leave to the Index or enter a Portal to the Unknown, which will put you back into human form, allowing you to change your Companion's skills. You'll be back in Werewolf Behemoth form when you return to the current stage in the Archive.
- Stone Garden: If you need to change your Companion's skills in preparation for the Arkasis boss fight within Arkasis's Laboratory in Stone Garden after you've grabbed one of the wolf tonics, you can return to human form by having your group wipe to reset the encounter. Unlike in the final encounter, the wolf tonics from earlier in the dungeon have a time-limited duration, so you can wait out that duration in order to be able to change your Companion's skills.
