Sorry if that is too many things.

im assumeing you mean hybrid build?

if so get a base of 70 int. Rest into either strength or dex depending on your gear.

well healer or well as in welling?

if welling u mite need to invest a bit of good fg on a mq heal charm
get about 100 intel 100 str and 80 dex if u can

str/dex plate is perfered and ee club with str/dex charm on main and acc = heal

if u want tank

heal mast wep
ee plate/chain
heal mast charm
acc slot = heal charm

Choose a mage as a weller.

put the 10 start stast point into vit and rest into Int
