Help: Trying to add slow down effect

I created a unit, it's a child and I gave him a ranged attack, now I want the attack to look like frost bolt, but I also want it to freeze the enemies and slow them down when it hits them, but I've been unable to figure out how to do it. I've switched abilities and used the attack from the undead tower, which freezes enemies when it hits them but it changes the graphic to the undead tower graphic, Instead of the Frost Bolt graphic that I want. So basically what i'm asking is does anyone know of a way to add the freezing effect without having to change the range attack graphic?

Sincerely,

Strom

Freezing breath does slow freeze

just put freezing breath as on of his abilities lol same what ssj4 said but he soemtimes...is unclear.

I've tried freeze breath but for some reason the game seems to ignore the slow down. I think I might just try to make a spell, like a freeze grenade or something to complement his attack that has slow in it. Rather than try to add slow to his initial attack. Maybe that might work better?

Sincerely,
