I'm usually able to keep everyone shielded for every infest in 25m. As long as you don't shield the tanks your Rapture CD will be ready for every Infest, and that will mean tons of mana when it procs on 15+ people at time. The shields tend to be a little staggered eventually due to Weakened Soul, the time it takes to blanket people, and the fact that Infest doesn't fully eat shields...so maybe 1-5 Infests will sneak through as the fight goes on but a huge portion of the shields tend to be Rapture procs still.
I usually end Phase 1 with close to full mana, about 80%+ with using PW:S, Penance, and PoM the entire time.
It's a long fight too, so remember that using Hymn of Hope and Shadowfiend early is a good thing, you'll get 2 uses out of them this way. I try to use Hymn nearthe end of Phase 1, and then Shadowfiend a little after we get to the edge in Phase 1.5. There's lots of AE damage there so I can spam PW:S, PoH, and PoM and still end that small Phase with ~80%+ mana. Then by time 5 minutes is up, I'll be around 15% mana, pop a pot and Fiend/Hymn is up any second and I can finish the fight from there easily.
Of course there's no need, but it's definitely the most mana efficient way to deal with it due to Rapture, this way all it takes is PW:S and a CoH. Helps the other heals keep their mana too.Originally Posted by MilkaMaus
