Going into Shadowlands, it seemed universally agreed upon that the Harmonius Apparatus was going to be the top throughput legendary for Holy Priests. Who doesn’t want Holy Word spells getting further cooldown reduction and indirectly feeding Holy Word: Salvation, right?
It wasn’t when I started trying to heal in mythic dungeons that I felt I was struggling more than most compared to Shamans and Druids (as usual). I considered Flash Concentration (or FC), though I was skeptical about it at first until I received a few recommendations about it. After a few dungeons and select raid bosses, I am now a believer.
Flash Concentration is a great pick among Holy Priest legendaries. It slots in either your wrist or neck slot. I selected the wrist slot for mine so I could apply a +15 Intellect enchant to it.
Each time you cast Flash Heal, Has its casting time reduced by 0.2 sec and healing increased by 3%, stacking up to 5 times.
For some reason, when I read that, I interpreted that it would apply only to your next Heal. That’s not what happens though. The FC buff lasts for 15 seconds. For that window, your Heal cast time is 1 second less which puts it as the same cast time as a Flash Heal and increases the healing throughput of it. You can squeeze off about 9 consecutive casts of Heal before having to hit Flash Heal to refresh it. Last week’s Fortified affixes included Grievous which was a struggle to heal through but having FC completely trivialized it.
Usage in dungeons
My talent setup
There is wiggle room. Shining Force gets the nod over Censure during a week like Necrotic where the slow and knockback can help your tanks shake off their stacks. I personally like Censure in most cases (largely because I’m not great in my Shining Force usage).
With the last row, you can make a case for Light of the Naaru or Apotheosis. I prefer Apotheosis just because of the on-demand reset for Holy Words in case something accidentally happens. This is my pug dungeon insurance. If I’m running with my guild or other players that I know consistently, I’ll convert over to Light of the Naaru instead.
Tip: Keep Mind Soothe handy. I’ve found it to be great when trying to get around certain packs.
Usage in raids
My talent setup
This is a slightly different setup for FC in raids. Enlightenment is now a necessity due to the increased time spent on the encounter. Cosmic Ripple gets you some increased passive healing. Censure or Shining Force is dependent on the encounter. Surge of Light continues to be valuable here to help maintain your FC stacks (otherwise I would just have Prayer Circle active). Halo is the main selection but there is merit to Benediction for certain encounters (like Huntsman and not breaking crowd control).
By default, I’ll keep Harmonius Apparatus equipped. For progression, I’ve got my awesome X’anshi, Return of Archbishop Benedictus pants! We’ll talk about that later though.
There are a few bosses in Castle Nathria where FC shines. If you’re working on progressing through Huntsman Altimor, I recommend using it. During Bargast, if your tank isn’t at full, a fully empowered Heal can help restore the Rip Soul spirits to full health quite quickly. It can top up your 3 players that have been hit with a Sinseeker.
On Mythic, it becomes even more crucial as there are more Rip Soul spirits that spawn off the Sinseeker targets. Whatever Holy Word: Sanctuary doesn’t catch, Flash Heal and Heal will finish off.
If you really want to have some fun, put this on when you’re about to start Sun King’s Salvation. Grab a healing orb, hit Kael with a Guardian Spirit, and start bombing away with Flash Heal and Heal. You will phase him into the Shade in no time.
I recommend using this Weak Aura to track FC. It doesn’t take up a lot of space and it comes with audio cues for time remaining on FC before it needs a Flash Heal refresh. Mine is positioned above my frames. You can see a Surge of Light weak aura right next to it (Thanks, Kyu!).
If you’re Holy, I can’t recommend using Flash Concentration enough for dungeons and pushing keys. I doubt it’ll make us crazy competitive at the high level but it’ll be more than enough to help get us through some of the affixes coming out. The cast sequencing does take a bit of time to get used to. I admit, I’ve let my fair share of FC stacks drop and really unfortunate times.
