1.13 buffs/effects animation edit

Here is a few questions:

1. Can I add buffs/effects to spells without buffs and then how will the buff work?

2. Shockwave has a stun buff but units with stun dont get stunned, how does it work?

3. Can I base a buff on another buff than something custom made from the basic buff?

4. Can I set if the buff should be dispelable somewhere and how do I know if I can dispel them?

5. If I make a copy of a buff and then both are added to same unit. For example Unholy aura + unholy aura (item) with 2 different buffs.

6. Can I add animations to abilities without anything written in the animation tag?

7. Sometimes "looping" is written in the animation tag and the unit doesnt have any looping. It means the first thing looping but isnt stand channel animations also looping?

7. How do I know exactly what they mean with animation strings. What to write if I have this string: Stand -1, if I just want to specific stand. stand;1, stand;-1 or stand -1?

Ive tested a little bit and I can answer this question:

5. Works perfectly!

I do not know the answers but as for No. 4, I think the new Buf Editing doesnt allow you to specify whether the buff is dispellable. It only allows you to change the art (I.E. Icon, animation) and the tooltip concerned. I dont think there is anyway to change that thing.
