smokescreen is still bug ? i have on my wizard . but it wont work . i dont see anything like smokebomb on my enemy

Do you have any SMOKEBOMB PROC? or Have you change your offhand special skill to smokebomb? Without smokebomb, smokescreen is useless. You can only spawn the effect of Smokescreen by the time your proc ticks or upon activating your smokebomb skill.

ahh ok what if i change my offhand but i put bomb proc ?

thats not enough put some bomb proc

That’s way better. But, to me Bomb proc is enough already. Don’t waste the slot for your offhand skill. Maybe you can change it to Stealth or something useful to your build.
