Barb earthquake cast to early

[Grafvalium2006]

Hello,


my Problem is, that my barb see the elite pack and in this Moment he cast the earthquake. I Need a timer to wait for 3 sec. after seeing the pack.
Is that possible?

I saw that:
if (await
CastPower.CastOnSelf(SNOPower.Barbarian_Earthquake,
context.CurrentTargetIsElite && context.TargetDistance < 20f))
return true;

float rendDistance = Hotbar.HasRune(SNOPower.Barbarian_Rend, 1) ? 17f : 12f;

But i have no idea how to say wait for 3 sec. / Maybe i can reduce the distance, or something else....

Furthermore i Need to say use only with elite...

Thank you

Bye
