Orb Cooldown

Using Black Arrow orb ability to cast a poison spell on attack. Everything is set to 100%. I have the cooldowns on both abilities set to 30 and it still casts every time consistently.

I searched for answers but couldn't find why the cooldowns don't work.

You can't give passive abilities (except Spell Shield and prolly something else I am forgetting) cooldowns.

What poison ability are you using.

You can give orbs cooldowns as long its the effect ability that carries the cooldown. Unless that no longer works..

If you use an autocast on-attack ability and you autocast and then auto-acquire a target, the cooldown will not take place. This is a bug with WC3 and may be related to your problem.

I'm using poison sting. I'm going to try setting the orb cooldown to 0 and leaving the poison sting ability @ 30

you cant set couldown to passives.

use orb of slow, it works well.

You can set a cooldown on the Orb of Slow, but this cooldown will be ignored unless it is a unit / hero ability.

Orb of Slow will only calculate proc chance if the unit is given an attack order directly - auto-acquiring targets will not work.
