Custom Countdown Weakaura

[Kronickhaz]

Hi all,

I'm trying to make a weakaura(progress bar preferred) that upon combat start will countdown from a set time of 10 seconds and then upon reaching 0 will restart counting down this time from 30seconds and upon reaching 0 will loop back from 30 until combat ends. It's to simulate the Fel Beam mechanic on Krosus. I don't know much about lua and haven't got a clue how to do it.

Yeah its just for Krosus, its so I can sit at a training dummy for 4hours straight(extreme example) and practice perfecting my rotation with his beam mechanic so that come Mythic prog I can focus more on the Orb and Add soaking rather than the basics.

That huge mess weakaura is kinda what I was hoping for, but I'm not sure how to go about making it.
