Do you want an aura that provides a bonus to nearby friendly units and decreases something of enemie units?
Well just gives two auras to your unit, one with positive value bonus, and the second with negative values. (To put negative values in worldedit, you have to to in File, Preferences, General, and check Allow negatives values in objects editor.)
You don't understand my problem .I want ONE spell that Gives (expample) Trueshot Aura to allied units and (example) Curse to the enemies who are in 900 area.
I made PotM with spell Beauty Aura ( it's base Trueshot aura ( aura do not give buff to PotM ( Done. ) ), and i want to make negative buff named Siduse, that units in 900 area ( like Trueshot Aura ) are with reduced attack speed. ( that's what i want to do, but when i threw Enemy in Stats - Targets allowed gives only Beauty Aura ( trueshot aura ) and they have bonus damage. ) ).
( My idea is to make Trueshot aura and Curse in one single spell named Beauty Aura. )
Still, you should use 2 abilites. Make one base ability, like you have done. Then make an invisible (based on an item ability) aura ability, with negative values for attack speed. Then make a trigger, adding a level to the negative aura for the hero each time she picks a level of Beauty Aura.
Trigger:
- Beauty Aura
- Events
- Unit - A unit Learns a skill
- Conditions
- (Learned Hero Skill) Equal to Beauty Aura
- Actions
- If (All Conditions are True) then do (Then Actions) else do (Else Actions)
- If - Conditions
- (Level of Negative Aura for (Learning Hero)) Equal to 0
- Then - Actions
- Unit - Add Negative Aura to (Learning Hero)
- Else - Actions
- Unit - Increase level of Negative Aura for (Learning Hero)
EDIT: Of course, spellbook is a smoother sulotion, as @Accname mentioned
so what you would do is set up a spell that does nothing to just show the icon. then make a spell book with your auras
and use the trigger necrach gave u to level up ur spell book
you cant level up the spells in your spell book. so your going to have to have 1 of each aura for each level
