Attack speed

Is there anyway to change the attack speed of a unit in the trigger editor? Im trying to get anytime a unit casts battle roar not only is the damage increased but the trigger allows the attack speed to increase. i used the search feature but i can't find attack speed only animation. but i'm not 100% sure if that means anything. my only other thought was to create a dummy hide it give it an item and make it use the item on the casting hero.

You'll have to add an ability to each unit that increases the attack speed or have dummies cast something on them to increase the attack speed (Unholy Frenzy without the HP drain, perhaps).

What you have found changes the speed at which the animation is shown.

In a similar case I created a Spellbook ability with the Gloves of Speed (a name like that) item skill inside, disabled this Spellbook on map init and gave it to the unit that had to be sped up using triggers.

But you're going for an AoE effect, I guess with a buff, so that may not be the best solution in your case.

The gloves of speed ability does not show an icon on the unit's command card as far as I know, so you do not need to bother with the disabled spellbook trick and can just add the attack speed ability to the unit directly instead.
