Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks List of skills above lv16

I'm taking a break from the game due to exams next week. However I'm eager to know if there are skills that require higher level than level 16.

Yes, there are.

Is there a link for the list or something?

Chain lightning, Meteor, Earthquake and Invulnerable all come to mind.

Really some of the most devastating skills in the game come rather late.
