Our inspiring friends, the Bards, are today's feature. Their first capstone does a little bit of everything, just like they do:
Bard Musical Prodigy
Prereq: Level 20 Bard
Cost: 2 AP
Benefit: You gain +2 Charisma, two additional uses of Bardic Music, as well as +2 to Spell Penetration checks and the DC's of your Enchantment spells. Your beneficial songs last 20% longer.
Edit: Insert standard disclaimer here, that I keep forgetting to write during my initial drafts. Subject to change during testing, may be nothing like this once it goes live, etc.
