Reposting here from Reddit, as I want an answer but also want to support using Lemmy going forward.

As the title. The text for Fused Staff says this:

When the item is in staff form, you can Cast the Spells from the staff and benefit from any other abilities the staff grants.

And (for example) the description for the Staff of Evocation says this:

While wielding the staff, you gain a +2 circumstance bonus to checks to identify evocation magic.

So I guess the question is, are you considered to be wielding the staff while it’s fused and so get the passive bonuses in weapon form? Or do they only apply when you switch it to staff form?
