Ring of Spell Knowledge states you can add one spell to your spell list but at a one level higher caster level. What in your opinion are the best limited access spells to place in a ring of spell knowledge?

He also makes a habit of starting fights by casting Spectral Hand. Delivering touch healing spells at a stupid range as a standard action makes a nice change of pace from laying down magic missiles and fireballs...
