Dread Necromancer- Spells per Day as 8th-level Dread Necromancer, CL 16
Bardic Music- Music as 10th-level Bard, 10 uses per day, Vest of Legends bonus, Inspire Courage +4, Inspire Greatness +3HD (3 targets), Suggestion traded for Song of the Heart, Heartfire Fanner goodies/brokenness.
Maneuvers- Douse the Flames once per encounter (not important), Leading the Charge gained via Crown of the White Ravens.
Badly needs Action Economy. Given that I have a lot of good music abilities, Song of the White Raven only really makes Inspire Courage (the weakest of them all) practical to mix into a heavy spellcaster's routine. To this end, pretty much everything except for Lord of the Uttercold, Negotiator, Skill Focus, and Residual Magic are expendable (granted, most of my feats have restrictions on what I can pick for them).
