I'm trying to set up a WeakAura for Mirror Images. So far I've got it to:
- Display something to show the ability is usable
- Display the cooldown till it can be used again.
What I want to see is a countdown till the images expire. I know the images last 30secs and I know the cooldown is 180secs, so I could fudge it by displaying (cool down - 150), but I've no idea how! Any suggestions?
