Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Help/Tips/Tricks Elemental Arrows and Enchants

I have ranger and I was wondering; do I need to have Savage Sortilege talent in order for elemental arrows ( freezing,shocking, fire ) to crit? It's elemental damage but scales with finesse so I got confused.
A similar question is; do weapon elemental enchantments can crit on its own ( seperate from my autoattack ) ? If so do I need the Savage Sortilege for that too?
Thanks, sorry for asking too much

Savage Sortilege only applies to *magic* skills - so basically any spell that deal damage. As long as you're relying on weapons to inflict damage, you don't need Savage Sortilege. Shooting special arrows is just basic attack. And all weapon skills automatically use your crit chance just like your basic attacks.

Not sure I understand your second question, but elemental damage from weapon is tied to your basic attacks, so it is multiplied when you crit (either with basic attack or weapon skill) and it is not when you don't crit.

Ok for example I put a frost rune on my weapon, so when I attack I also deal 60 water damage. Then when I crit, will this water damage still be 60, or gets higher?

It's higher. Multiplied by your critical bonus.
