Will can help, but I belive there are times where he can't face for you. Like talking with others at camp.
I'm going to pitch the Seto Kiba build. The White Dragin sorcerer.
If you go human you'll get shield and light armor, letting you get a reasonable ac.
The meat of this build comes in with the free Armour of Agathys white dragon gives you. Which can be upcasted
Meaning you end up as a great striker and blaster that will be pretty tanky and can quickly deal 15+ damage to enemies trying to attack you for free.
