Can we make Tornado Slow (Aura) show up as a skill?

I'm using Slow Aura as a skill that can be leveled up, but it doesn't show up in the UI even after you put points into it.... Any ideas, or replacement spells? The effect is there coz I can see the enemies are slowing down, and they have the buffs on them, but there's no UI button for the new spell.

u have to assign a button and position before it works.

How I would do it is making a dummy skill based off Bash which does nothing but has the proper description etc for slow aura, then have a trigger, then make a trigger to add slow aura to the unit when it learns the dummy skill.

Thats the only way I know how to do it, too. Same with a skill based off something like, say, the Runed Bracers' Magic Resistance.

lol, my idea is to edit unholy aura that does the opposite of tornado slow aura, change the values and give the Tornado slow (buff)

make an Dummy Brilliance aura or bash, and add trigger comparison to add the level1,2,3 aura to unit when he learns level1,2,3 dummy spell

also, i figured out how to Turn on and turn off passive abilities....
the idea is the following:

make a Defend dummy spell that has everything set to zero,
with position X2, Y2, and turn off position X2, Y1...
lets say it has 3 levels, level one turns on Bash 1, lev 2 turns on Bash 2 etc....
make Bash 1,2,3 with positions X2,Y2

when u learn the skill, it explains everything blabla, and when u activate it, Add coresponding bash to the unit activating Defend, so u'll have that bash skill where the defend icon was, and the turnoff will move one square up. because the defend has everything set to 0, normal units won't raise their shields cuz they got none, and won't slow down either.
When u deactivate it, remove the bash skill and voila, the "turn on bash skill" goes one square down, and it's all set for use again...

i haven't tried this method yet, it just came to me right now, but perhaps these triggers will work...

E: unit "activates" defend
c: unit activating defend equal to your unit
a:
set variable N = level of activated defend
add Bash [n] to activating unit

e: unit disactivates defend
c: unit disactivating defend equal to your unit
a: remove bash1 bash 2 bash 3 from your unit

this triggers are just a guideline to how it might look like....the actual triggs might be a bit more complex, cuz triggs like this probably don't exist...also there might be a problem detecting if the Defend has been turned off, i'll experiment with it, and then get back at you with the results...
hope i helped with the slow aura tho :)

I think Command Aura with negative values it's better because slow also AR%

look @ my tutorial....it also works for skills that don't show up in game (like runed bracers or phoenix fire etc...) but u'll have to make slight adjustments cuz it's mainly for activating/deactivating passive skills
