Re: Why can't I use thousand cuts? I have all the skills for it.

There's an item upgrade that gives you an n% chance to cast thousand cuts at random, which is super powerful. I use that instead of the ability. 🙂

Edit: I was wrong. It was hidden blades and it's always 10% chance. It comes from masterworks: https://dragonage.fandom.com/wiki/Crafting_materials
