Feat: Rune-Singer

You practice the lost art of using music to guide your rune-carving, singing the runes into existence as much as crafting them. You can use Performance instead of Crafting when attempting Crafting checks related to runes.

Once per 10 minutes, you can Trace A Rune with song alone. When you do, you use the 2-action version of Trace Rune as a single action without needing an artisan's toolkit, and you remove the action's manipulate trait. You don't need to be able to move your hands when Tracing a Rune using song, but you do need to be able to sing in a clear voice.
