I don't use Physick as a main heal over Adlo, since it heals and mitigates damage. For Critical Rip I pop Adlo then begin casting a Physick as the cast bar gets 3/4 of the way so I know my heal hits my tank right after the move goes off. I replicate this for the tank majority of the fight because the auto attacks aren't exactly gentle. If my tank is 2K under I pop an adlo if they are more I pop a physick then an adlo, but adlo is my primary healing spell. I average at least 30% Adlo usage on T9 before 2.4 according to Shi. I've not checked since then.

My MP isn't unmanageable and I don't think Yukari was stating that he is "burning through MP", but that he needs more of it this coil as there are more big hits to look out for, for tank and pt members. I think we are more agreeing it is nice to get the extra boost of PIE with the BiS I've selected, but my main stat focus still remains on CRIT and DET.

A number of reasons, I over exaggerate a bit at times, but I'll try to break it down:

1. On consumables I pop Crit/Det food as well. As far as ethers go I always pop them as precautionary. So I'll usually be popping one at around 60-70% if I know I'm gonna be burning some mana and aetherflow/energy drain wont be enough to bring me back up.
2. I utilize adlo more frequently. In addition to big incoming damage abilities and single target preys, I also swiftcast + adlo the double preys - as precautionary. Turn 12 also has a lot of adlo usage as well. I figure the more work I can take away from the WHM by being more productive the better, and I hardly ever try to ask for mana ballad as it's counter-productive to dps, I let them make that call.
3. I'm always trying to DPS/Bane/Energy Drain. I only ever try to keep 1 stack of Aether for incoming Sacred Soil/Lustrate if the situation called for. I never give myself downtime.
4. I que up heals all the time, a habit that carried over from WoW. Not sure how relevant that is here because of animation delays, but essentially what that means is I get a lot of physicks going off to the tanks to keep them topped off in which some can and do result in overheal, but that's a risk i'm usually willing to take - better safe than sorry.
5. Execution, the perfect run seldom exists so there's always unnecessary damages going out and raises happening which results in mana loss.

I use Physick more than most other people do so that's more than likely where the mana drain comes into effect.

And yeah, what Kirana said, it's not unmanageable. If it was then I'd be in trouble. A little adjustment here and there and problem solved, but more piety would be just greaaaaat…..

SCH Tips/Tricks - Turn 12 Phoenix:

This is a 4 Phase fight that is heavily reliant on DPS up until you get to the last phase primarily because of Bennu's, which will become an issue in Phase 3. I won't get into fight specifics or go into the fight in great detail, but only cover a few healer specific bases. Below I posted a guide that gives a more in depth look at the abilities being used.

I feel like this fight really pushes you to do as much DPS as you can while still managing to heal as much as you can, moreso than the previous encounters.

Phase 1: Light Heals, Lots of DPS. 100% - 80%
The damage in phase 1 is relatively light. The only major damage that goes out is during Revelations which deals massive damage to the tank, and anytime a Bennu spawns, which is tanked by the OT - They hit REALLY HARD, but die really fast. The key here is learning how to manage shields on your tanks to prepare them for Revelations and landing a well timed Lustrate, or even a Physick on the OT during that Bennu so that you can spend more time damaging the boss. A few tips:

• Bane is love, Bane is life! - You will be using a lot of Bane
• Bennu's always spawn on the boss in Phase 1, so Baning dots from Phoenix to the Bennu's will help those die a lot faster. If you're confident enough, shadow flares are great here as well. Feeling more confident? Energy Drain, as long as you remember to keep an aetherflow up for Bane.
• Take the time to perfect your rotation and don't panic. Communicate with your healer counterpart on when you will be in cleric stance so they get a better understanding of when they should be alert on heals, because they can and should also be finding time to damage the boss as well, so it's mutual.

Another mechanic that you need to worry about here is the Blackfire/Whitefire ability that Phoenix casts. Essentially he drops a Black Fire on 3 players(1 OT, 1DPS, 1 Healer), and a White Fire ring around 3 players (1 Tank, 1 DPS, 1 Healer) that need to overlap the targettable Blackfires in order to give them a Max HP down Debuff. Once the White Fire goes off, it causes raid wide damage, very easy to heal through. Once the White Fire's go off, those Black Fires need to die, Bane works wonders here:

• I like to pop a Succor as he's getting ready to cast his Blackfire ability to minimize the amount of damage taken by Whitefire.
• Learning the timing of Blackfires and when they drop on each player is crucial to success in this phase, so count it out in your head and make sure you're placing those blackfires where they need to go.
• Reapply dots if they've fallen off, once White Fire explodes, Bane your dots from the boss, onto the Blackfires. If you have a SMN in your group, both of your dots will be more than enough to destroy the black fires without anyone else targetting them.

Phase 2: Heavy Heals, Heavy DPS. 80% - 53%

As soon as Phoenix begins casting Brand of Purgatory, that is indication that Phase 2 has begun. If you haven't already, please see the link below to get a better understanding of the mechanics used in this phase as it is a lot to explain.

If you are assigned to dealing with the Brands/Flames of Unforgiveness, a few things to keep in mind:

• Phoenix always begins casting Flames of Unforgiveness shortly after a Bluefire explodes. So make sure you and your Brand buddy are in position/topped off/ and shielded in preparation to make the swap.
• Only one person should be moving when passing the Brand, this is to avoid movement delay that happens in this game. A single side step from your buddy while you're moving over to transfer can mean missing the transfer completely and causing death.
• The best and safest way to deal with this if you're the only one responsible for healing and topping off the Brand players is to Make sure Adlo is on both of you before a Bluefire Ring explodes and once Flames is being cast and you make the transfer, immediately reapply Adloquium on the player who is going to take the secondary damage from Flames and have your pet heal that target for safe measure. Don't be afraid to Lustrate if the target is below 3k hp with adlo(noncrit) as the damage from flames varies and can gib anyone below 3k hp even if they're shielded.

Another ability is Red Fire. If your Healer Counterpart is dealing with this, you will have to be mindful of that as they gain a debuff that greatly reduces their healing/dmg done while they're dealing with that Red Fire, you will need to not only make sure you're on top of topping off your Brands and Shielding, but also watching both the Tanks as Bennu's do continue to spawn and Revelations also persist during this phase. A few things of note:

• Learning the Intervals of when each ability is cast is crucial to getting better and being able to pop in and out of cleric stance for DPS. So pay attention to that.
• I like to pop into Cleric Stance immediately after Flames of Forgiveness goes off to begin a DoT Rotation on the boss and pop right out to begin heals on the tanks and prep for top offs and shields once again. Even though the brand target will drop really low, they shouldn't take any further damage after that until the next Brand Transfer, so you can just have your pet top you guys off while you dps and shield tanks.

Phase 3: Heavy Heals, Light DPS. 53% (Adds Phase)

This phase begins as soon Phoenix flys up into the air. Bennu's will respawn and the adds phase begins. Phoenix will continually cast Flames of Rebirth which deals raidwide aoe damage that increases in damage each time it is cast(Soft Enrage mechanic):

• Keep Phoenix on your Focus frames prior to going into the phase if you haven't already at the beginning of the fight. It is helpful so that you can time your Succors/Soils better.
• Eos is GREAT here!
• There are Small Bennu's and Big Bennu's. The big ones hit really hard, the small ones not so much but there are quite a few of them so the damage adds up on the tanks. Keep them topped off. If they are low and a Flames hits, they can get auto'd right after and that will result in a tank death.
• Flames of Rebirth will be unhealable after 14 stacks. So if you're making it that far, throw everything you've got for mitigation on your team. Using adlo's on your physical dps as they have the least amount of magic defense.
• Running into that phase it is possible that your Healer counterpart may have the Bluefire debuff on them still which means reduced healing. Bare this in mind as you will need to pick up the healing entirely until that debuff wears off.

Phase 4: Light Heals, Light DPS. 53% - 0%

I don't want to say that this phase is a pushover, but it is much easier than the previous ones in my personal opinion. It is a good idea to ask for a Mage Ballad from your bard if you're running low on mana running into this phase. If you went into the adds phase with 4 Bennu's only, you will have more than plenty of time to beat Phoenix without hitting Enrage.

The phase consists of a few dodge mechanics and debuff mechanics that need to be dealt with(Fountain of Fire). Revelation Persists and so does Brand of Purgatory, however, it is so much easier for the Tanks to deal with it at this point rather than the ranged/healers.

The phase can be difficult if you lose track of what damage is going out on the raid/tanks and people taking unnecessary damage from phoenix landslides/focus dives. Unlike the other phases, it is unpredictable if people don't pay attention. A good way to deal with this sort of chaos is to assign priorities to the healers during fountains. One healer focuses tanks primarily while the other watches the rest of the raid. A few things of note:

• Flames of Unforgiveness is a pushover on the tanks. As long as they're topped off they don't even need to be shielded as it won't destroy them, and an auto shouldn't kill them afterwards, just be alert.
• Revelation always happens shortly after Fountain is summoned, so you do want to pre-shield the current tank to mitigate that damage, regardless of what your healing responsibilities are.
• Fountain Targets take damage as they are accumulating stacks, furthermore, they can also be linked to a phoenix that will dive into them which means they will take that damage as well. If they are, be sure to shield them and keep them topped off if the raid is your priority.
• Keep your eyes open to watch people linked to phoenixes as they will be the ones taking the dive damage. Also watch for bird landslides that you need to move out of.
• You can also be linked to a phoenix, if that is the case, you need to move and point that bird away from everyone else so that it only hits you.

He continues to cast Flames of Rebirth, however it doesn't deal as much damage, just make sure succors go out and a sacred soil should do. He flys up after 2 Fountain of Fire rotations to cast Plumes and Phoenix Dive/Landslides, so it's purely a dodge mini-phase, and then you simply repeat the whole process.

Hope that gives some insight on the fight from a SCH perspective. It isn't the best, but only my own experience and personal opinion. :)
