A little help with power auras

[Deleted]

Ok I am trying to make a power aura that shows the cooldown of icy veins, that I also want to use on other spells.

Anyways, I don't want the cooldown to show in combat, but I do want it to keep showing the cooldown 20 seconds after combat. Is this possible?

This is unclear.
You want it invisible in combat, then when you leave combat, if there's < 20 seconds on the cooldown you want it to appear?

No I want the icon/cooldown to still be shown 20 seconds after I leave combat, and then vanish.
