Gives you +10% Fire and +10% poison resistances.
Sophisticated is a talent in Divinity Orignal Sin 2.
By default you can get up to 100 resistance for any element with your gear. Potions or skills, like Poison skin, can go higher (so they will heal you). It's a good combo with Demon (20% fire resistance, so one great potion will turn it into 110% from scratch).
does poisonous skin and flaming skin when used allow that attribute to cause healing?
If you’re an undead Lizard, does the 10% poison resistance transfer over to resistance to healing items?
