Speed spell issue

[GermanGood]

Hey I'm making a custom spell which increase the speed by 2 and the issue is when I cast the spell the hero stops for a second and then speed up
is there a way to disable the casting spell or something? so when a player press the spell it will just speed up and no stop then speed up

There are a few spells that can be cast during movement with no need for the animation to play, in your case you might use Berzerk (the orc troll spell)

I think the item ability "Rune of Speed" (APsa) works like that and doesn't stop the unit from running?
