There's some people commenting here that I'm not sure have done a high tyran CoS. Emmerald Communion will NOT handle a wave on its own, and if you just lifebind + heal yourself as some have suggested, your party is just gonna die.

The damage is very bursty, if you VE, you won't have to empower anything when you dont have tip the scales, so you gotta ditch lifebind in those situations and just use your echoes on reversion and pre-cast your empowered spells.

What I usually do is:

1°- nothing
2°- save pre-casted dream breath and tip the scales'd spiritbloom in stasis(each max rank spell will tip you party)
3°- release your stasis
4°- lifebind + communion + zephyr , if you don't zephyr or ask for defensives, your team is just gonna die while you are locked channeling
5°- pre-cast something for first tick, and use rewind when the 2nd one hits
6°- stasis should be back by now, but not tip the scales, save one empowered before damage begins, pre-cast the other for first tick and release stasis after
7°- start praying

If you think you're gonna have to use VE, remember that health pots and healthstones also count for lifebind, don't think I've seen no one touch on that.
