A few questions

I couldn't find on guildwiki enough info so pls can some1 answer this

1. What dmg type does avatar of lyssa and it it affected by criticals?

2. Is +dmg from skills enhanced by critical hits and from +15% and +20%(customized) weapons? If not than whats the use for +15% dmg if u can use instead a +5e mod?

3. Shatering asault does only 50 dmg per hit or it's a sum from SA and weapon dmg? and is it affected by criticals?

1.) whatever damage type your weapon and/or dervish/monk/etc enchantment spells allow you to do, yes, critical hits will increase the damage

2.) depends on if the damage is a + amount or a set amount, ie +17 vs 17 dmg. +17 would add on top of whatever the weapon did, which may have been adjusted by a critical hit, a straight 17 though would not be adjusted by a critical hit. Not every build needs more energy. so the +15% allows all your attckes to do a bit more damage (base weapon damage) which means the mob dies just a bit faster

3.) depending on your dagger mastery, yes it just does 50 per hit. You can get a critical hit while doing it, but the damage won't change, you'll just get energy back from your critical strikes attribute.
