This answer to a related question I've asked helped me understand that, given a specific skill, I don't really know what affects its performance.
So what I'm looking for is concrete data: given skill X, what affects it. In particular, given skill X,
- Is it affected by faster cast rate?
- Is it affected by +knockback?
- Is it affected by attack speed?
- Is it affected by weapon damage? And if I'm duel-wielding, from which one?
- Is it affected by +elemental damage attributes?
- Is it affected by +% elemental damage attributes?
I couldn't find any online data about that.
