Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General Mechanically, is Fane the best story character?

Depends on what you want your avatar to be.

If you want your avatar to be a battlemage then I would say Loshe is hands the best to be both your avatar and a battlemage.
If you want your avatar to be a charismatic canibal polymorph,then yes mechanicaly Fane is the best.
If you chose Fane to be your battlemage and you recruit Loshe,then as far as I am concerned that is not the best - but you could still make this combination work or even surpass the combination I mentioned if you play your cards right.
