the ones i found i mostly used are self heal, group heal or heal division, holy word, and the most important: Blessing.
those saves me a lot of time and gold.
my warrior is currently lvl 34 with warrior mastery at 34 and cleric at 25
and when my party needs a healer, i become one. ( on the site note i am full str and somehow i still manage to become a good cleric

)
this build is most of the time refer to as the "paladin" build, but its more like a variant. i am NOT putting any sp into the one hand sword + shield tree though
