This is the healing check boss of the dungeon, and it's a really good boss, letting you go all out doing as much healing as you can and sustaining it for a long period of time. It's
also a boss that is a bit hard to prepare for because it doesn't have specific points in the fight where the damage ramps up so it doesn't have clear "press your cooldown here" spots. Instead
you're fighting a constant amount of damage non-stop while also avoiding some simple mechanics
For the normal mechanics, you need to hide behind an 386222 to avoid the damage from 386757, and have to move between the circles in the floor to not get hit by
386559. These are very simple mechanics that even when failed won't increase the amount of healing you have to do because whoever fails them will simply die. The only important
part for you is 386741
386741 will deal a constant amount of damage (it does not increase as the fight goes on) to everyone in your group all fight long. This damage is not trivial and 100% of your
atention should go to keeping your raid alive. Most of our good healing depends on short cooldowns so the key to handle this is to stagger these short cooldowns so you can cover the damage
without falling behind, using your cooldowns to supplement spots where you run dry of other buttons. It's important to keep in mind that you need to be okay with people not being at 100%
HP all the time, your goal in this fight is keep everyone alive and sometimes the most efficient way to do that is to let them get a little low before hitting with a burst of healing like
echoed ve or sb
For example, you can start the fight doing ve into stasis, followed by ta, db and staying there casting lfs on the boss for damage, the double
db hot should cover the group for a little while and then when they start dropping low you can send a max rank sb. This fills your stasis with all the high value spells you
need but doesn't waste the sb into overhealing right as you pull. After that you should spend your essence keeping rev on your group members, because of timeb it's
much more valuable to keep real revs on them as oposed to revs from taechoes.
db has a 16 second duration with a 30s cooldown which means you can have it active for half the time, you should always have coy up before using it and also ideally apply
a ta right before it to get the double hot on everyone.
You should have a general plan on what order are you gonna use your cooldowns in: ec is ideally best used early in case the fight extends longer than 3 minutes so you can use it
again at the end to recover some mana, but also shouldn't be used so early that you waste the mana it gives you back, while rewind is more flexible and can be your 2nd catch up
button. Don't be afraid to use some extra echoes to lb your rb and sometimes rescue and ally for the tg shield.
