I'm considering multiclassing my alchemist and I've been thinking about how item creation feats work across classes.
For example, if I take a level dip in bard, I now have a caster level (alchemist, RAW, does not) and could then take for example Scribe Scroll. However, since my caster level is a part of my bard abilities, does that mean I could only make scrolls of my bard spells? Or could I also make scrolls out of alchemist formulae? I can see the arguments for both interpretations but I am curious what the community thinks.
Creating magical items usually requires preparing one or more spells. Alchemist extracts are not prepared spells, and they do not fulfill that requirement. But you can ignore this requirement, and even prepare spells outside of your class spell list, if you increase the CR of the crafting check by 5.
With some magic item creation you can bypass having the spell, however that is not the case for scrolls. You must have the spell prepared to create a scroll.
That said, I think most GMs would be willing to let an alchemist scribe scrolls of their extracts.
Yeah, the DC increase specifically doesn't apply to things like scrolls, because that's pretty game-breaky. ("Hmm, I don't have this spell I want in my spellbook. I craft a scroll with the spell I want and increase the DC. Then I copy the scroll into my spellbook. Magic from nothing!")
I don't think I really explained my question well. What I'm wondering is if once you have an item creation feat from *one* class's caster level, if that can then include every class's resources. I see no real reason why it would not, but if there is a RAW one way or the other I'd like to know.
If your question were about a cleric/wizard multiclass the answer would be that you can use either class to supply the spell or pq. But alchemists aren't spellcasters, except for the ways they are. So answers to your specific will tend to vary or have some shrugging included.
