Witch Assistance

[metalith]

Looking for Optimization and build Assistance with a Witch

The concept idea for this character is a former captive that was adopted when the local witch doctor discovered he was touched by the spirits and decided raised him.

Anyone have a clearer idea what the Adopted Trait provides. It kind of read something like providing Ferocity or Weapon Familiarity.

I have a 16 Int since the Scarred Witch Doctor Archtype doesn't say Concentration and Spell Penetration are also based on Constituion so I'm assuming they are still Int based.

Pondering flipping 10 & 16 between Str and Cha
