3rd level: improved unarmed strike
6th: natural spell
9th: improved grapple
Ithamar's stats are good. Wisdom highest with Con in 2nd.
Summons and animal companion will be your low level meat and potatoes. Pack vigor for healing instead of cure, better efficiency. You have passable combat stats, but use a sling primarily, with a scimitar/wood shield for when you can't shoot things.
