1 spell slot of each level up to 5th, plus bonus slots for your Int modifier or Wisdom modifier depending on which focus you use that day. Caster level 20th, since it's equal to 2x your class level and presumably you ate the brain of a Chameleon 10.<br/><br/><br/>EDIT: though a bonus, note that Arcane/Divine Focus says 'any arcane/divine spellcasting class', casting as a cleric (so prepared magic). You can pillage any and every arcane/divine spell list printed for the best spells at any particular level.
