Okay so I am trying to give my hero a passive ability that allows them to add Slow (ice) to their basic attack. I have tried multiple times to make it work, Even opted to change the ability to slow aura or even bolt of ice. Every time the ability doe snot slow the enemy. i checked frost attack (from nerubian towers) and it says Buff>slowed so why is it not working on my hero? I give the ability to be passive and say buff>slowed.
