Divinity: Original Sin 2 - Final BOSS (Solo/Tactician/Fane The Deathknight + Ending)
Divinity original sin 2 final boss played on tactician, solo with fane. Well much easier than the doctor since you are not alone in this fight. But damn...got lucky with meteor spell, it almost killed me :)
I chose the 'divine' ending or whatever you wanna call it.
