I've intentionally left it as bare as possible. I'd sooner have too little and we then add to it than start out too extreme.
Food of Love as a flat immunity is against the design principles I was working on.
Sonic Resistance 5 on its own would be fine as a half ability, however.
Words of Power on its own is a half-ability; for the base Poet it's uninspiring (1-2 inspirations for a spell isn't a great trade-off), but would the Banshee, for example, be happy to spend a level 1 spell to AOE damage/stun an extra time?
Any ideas on toned down versions of the capstone that might make another half ability or two?
