Buff Problem

What ability must I use to add to that unit a buff??? It can be an ability that don't do anything or can be an ability with some little effects . Will the unit can have 2 copies of that ability and will it have 2 different buffs ??

I think you can't understand my question. OK ,I will reform it. How can i add a permanent buff to a unit (that buff shows some that the unit has - Has Splash Damage - Has Frost Attack ....)? If the unit has that buff ,your opponent will see that the unit has something special .

Base your ability on a dummy aura or something like that.

You're going to want to modify "Slow Aura (Tornado)" to make it only affect the caster. After that, I would hope you can figure it out yourself.

sphere works fine too

Sphere doesn't grant a buff.
