Say I create an Elf Fighter, taking the Otherwordly Magic ancestral feat with Shield as my cantrip, and then select Reactive Shield as my 1st level feat. Can I use Reactive Shield to cast Shield?
Reactive Shield (Reaction): You use the Raise a Shield Action and gain your shield's bonuses to AC immediately...
Shield (1 Verbal Casting Action): You raise a shield of force to protect you. This counts as using the Raise a Shield action...
I'm assuming it wasn't meant to be used this way, but RAW looks like you may be able to.
Seems like a pretty excellent way for a ranged/no shield fighter to grab an extra AC bonus as well as reduce some damage in an emergency, if it's possible.
