Question: I am in a campaign where I want to be a Gnome Bard that can use the Fire Descriptor for the Music Damage, but my GM will only allow me to Multi-class into either Druid or Cleric For campaign purposes. Is there any hope for me? Maybe with a trait or another Feat?

Ref: [Fire Music Feat](http://www.d20pfsrd.com/feats/general-feats/fire-music)

Answer: 
You could use the [Arcane Talent](http://www.d20pfsrd.com/feats/general-feats/arcane-talent) feat to learn [spark](http://www.d20pfsrd.com/magic/all-spells/s/spark), a 0-level spell with the [fire] descriptor. The wording of the feat should satisfy the necessary requirements:

> 
> Choose a 0-level spell from the sorcerer/wizard spell list. You can cast this spell three times per day as a spell-like ability.
> 
> 
> 

The [Paizo FAQ](http://paizo.com/paizo/faq/v5748nruor1fm#v5748eaic9qow) clarifies that spell-like abilities count as being able to cast that specific spell for prerequisites, and (right underneath the previous question) by default will count as arcane spells from the sorc/wizard list.

You should probably also consider the [Pyromaniac](http://www.d20pfsrd.com/races/core-races/gnome) alternate racial trait, since it augments fire spells, but sadly it doesn't grant any arcane casting that would qualify you for the Fire Music feat.

That said, I'm not really sure *why* the feat requires the spell be arcane, so it might be worth discussing options with your DM.
I'm not sure about the wording, but I think the trait [two-world-magic](http://www.d20pfsrd.com/traits/magic-traits/two-world-magic) may be relevant:

> 
> Benefit: Select one 0-level spell from a class spell list other than your own. This spell is a 0-level spell on your class spell list (or a 1st-level spell if your class doesn't have 0-level spells). [...]
> 
> 
> 

On one hand, it allows you to gain a spell from another class's spell list, but on the other hand, it becomes a spell in your list, so it might not qualify. Consult your GM...
