Only healing spell Silver has is Stabilize, which only stops us from bleeding out when we're already dying. And I don't think oracles need a specific deity. >.>
Confirmed: "Unlike a cleric, who draws her magic through devotion to a deity, oracles garner strength and power from many sources, namely those patron deities who support their ideals. Instead of worshiping a single source, oracles tend to venerate all of the gods that share their beliefs."
But I guess you could have one anyway.

Also, if this person doesn't join, I can make a hedge witch (and play two characters). Can take the healing hex and cure light wounds.
