Refresh Dia at 0-2s remaining (avoid dropping)
Glare III (or
Holy III on 3+ targets)
Rotation and Healing FAQ
Why are PoM and Assize used later in the opener?
PoM and
Assize are held until 3rd/4th GCD to maximize damage under raid buffs, however they can be used earlier if you end up losing a cast or can get better alignment with add phases, etc.
How do I use lilies?
Misery is 1240p and takes 4 GCDs, 4 Glare IIIs is 1240p. Thus, you should typically avoid capping lilies even in full uptime and prioritize using them for healing and movement where necessary. Lilies should be used in downtime whenever possible as they are free potency gains. If misery can be used to cleave any additional targets, then lilies become a substantial damage gain.
How do I heal dungeons?
Regen and
Benison to keep the tank healthy while gathering mobs,
Dia on multiple mobs while running, drop
Asylum where tank will be stopping, and
Holy III once the tank has stopped.
Holy III still has a full 2.5s cast so weaving additional mitigation and healing is typically done via
Solace or
Regen once the tank starts taking damage. Lilies should be used between packs as often as possible to maximize
and
casts on larger pulls.
Stat Priority and Melding 
General Stat/Meld Priority:
Magic Damage >> Mind >> Crit > SpS to GCD tier > DHit/Det
when raiding, they are a very effective way to recover from multiple rezzes or a death. (ty Tonto)
The lily changes in 6.1 drastically improved our MP economy, so we require far less piety than we used to.
Gearing Priority and Best in Slot

Mid-Piety General-Use Set
2.44 GCD | 621 Piety https://etro.gg/gearset/e2fc82de-9629-48fd-ad46-5b13be00aaba
Garlean Pizza while a couple slow sets use
Carrot Pudding. Use pudding if you're unsure what to take or have transitional gear.
Tincture of Mind Grade 7 is the best current potion, but keep some
Super-Ether's handy for prog.
Ultimate Sets 
The Omega Protocol Sets
These sets are preliminary but should bring sufficient piety for prog based on previous ultimates without sacrificing a ton of damage. Feel free to bring more piety if you want to be able to cover more raises or GCD heals. I would highly recommend bringing one or more piety swap items for early prog just in case you hit a phase where you suddenly want a ton more piety. Piety melds also work in a pinch. I prefer swapping most of my DHit melds to Det for prog for slightly more healing, but it won't make much of a difference overall and keeping your DHit melds for parsing etc. is completely fine. There are some additional sets in the https://bit.ly/WHMGearCalc, and prog sets from other healing jobs will also work just fine. Make sure to bring tons of
Super-Ethers.
Mid-Piety TOP Prog Set
https://etro.gg/gearset/00e98ace-9cc5-4f97-b8ae-c4dd6980f4ea
Super-Ethers. The Det melds in these sets can all be swapped for DHit melds if you want a bit more damage and don't need the extra healing. There are some additional sets in the https://bit.ly/WHMGearCalc including min-piety sets that should only be used for rekills in more optimized environments.
Note: Manderville Cane (ilvl 615) is very slightly better than Asphodelos Cane for DSR prog (by 9 crit), not enough to go out of your way to get but worth noting as an alternative. It is NOT better than DSR Cane.
Low-Piety DSR Prog Set: https://etro.gg/gearset/57e81486-cd1b-4b47-8307-c060539faca3
Old Ultimates
ShB relics with customizable stats are by far the biggest upgrade you can grab for these. Prioritize Crit>Det for synced gear, but make sure to have 3-4 piety slots for prog and bring tons of
Super-Ethers.

Tips and Tricks
Ground-Target Abilities
Asylum and
Lilybell are notoriously annoying to place without clipping and are one of the few cases where macros can be a viable solution (though still liable to clip since they still cannot queue). You can find some example macros here: https://pastebin.com/FR95WmSX. You should still have non-macro versions of the keybinds on your bar in the event you need to place these abilities on something you cannot target.
Another solution for this issue was added in 6.0 and allows you to press your keybind twice to instantly place your ground-targetted ability. This setting can be enabled under Chacter Config -> Target -> "Press Action Twice to Execute"
