Slow Aura Tornado question

Hi guys, I have been recently introduced to the concept of "slow aura is the perfect buff because it always stacks", However I don't know how to use it. In a simple and quick test map I made, I use 2 slow auras in my priest, but the effects of the auras don't show up. What am I doing wrong? Who to use this ability properly ?

Different auras only stack properly if they use different buffs.

Just a quick note: those field values in the Data section should not be negative.

Weermmm, so you are saying I have to change the buffs from the auras right? Like Endurance aura plus Brilliance aura ? Thx

Why not?

Because it didn't even slow the units. Did you even test your own demo map?

....................................................

Yes, and the priest was moving slower =S

I was referring to the values in NewSlow2, sorry for the mix-up.

Like this :

( for triggered condition / buff system things )

Ahh, thx now I understand how to use tornado slow aura!
I would give your rep++ (but wc3c won't let me) because you make no idea how this is important to me and my project. Thx a lot really ! You already have credits in a mini.system of my map, but this is something greater xD
