Favored Soul/Battle Sorcerer

[EyeontheMountain]

This screams out "Arcane Disciple" to me. Basically, the feat lets you add a cleric domain to your arcane spellcasting list. So you can select the "Good" domain and throw down Holy Smites and Protection from Evils, or the "Healing" domain and function as a party healer.
.

The problem being that both FS and BS have to choose their spells. And can still only castthem once per day. Arcane Disciple works far better with a class that knows their entire list likea beguiler, for example.

If I only ahve 2 3rd level spells known, choosing CSW (Which I can cast once per day only) really limits my spell versatility, which is weak for a BS anyway, as n they generally know one spell fewer per level than a sorceror.
