Now granted, my knowledge of Ulduar is still quite limited. I’ve only run the zone on heroic. I’ve only experienced 7 fights. I’ve only defeated 6 bosses. But even so, I’ve already witnessed a couple of encounters that have caused me to reconfigure Grid.
I’ve written more in-depth instructions elsewhere, so I won’t go into too many details here. But sufficed to say, if you are new to healing (as it’s your dual-spec, or you’re newly 80, or you’re new to raid-healing), I highly recommend you use some sort of healing add-on to help you better monitor the health, mana, HoTs, buffs, and debuffs of your raid members. There are several add-ons you can use (Healbot, VuhDo), but I prefer Grid.
In Ulduar, several of the bosses I’ve fought thus far have abilities that target one or two raid members and that require healers respond instantly. As with Kel’Thuzad’s Frost Blasts, players who are targeted take immense damage over a short period of time. And while add-ons like Deadly Boss Mods can announce the victims to the raid and while people do typically holler this shit out in vent, if you’re like me — playing whack-a-mole with your unit frames — then your best bet for a quick reaction time is to have the indication show up there.
To open your Grid settings, type /grid config.
Go to the Status tab, then to Auras. There you can Add New Debuff.
Although I doubt this is a complete list, here are the ones I’ve added so far:
Ignis the Furnace Maker
Slag Pot: Charges a random target and incapacitates them, inflicting 5,000 (Heroic: 10,000) Fire damage every 1 second for 10 seconds. If the target survives, they will gained 100% (Heroic: 150%) haste for 10 seconds.
Light Bomb: Causes the target to inflict 2,750 (Heroic: 3,500) damage to other players within 10 yards every 1 second, for 9 seconds.
Gravity Bomb: Causes the target to spawn a Gravity Bomb after 9 seconds, which pulls other players within 20 (Heroic: 10) yards and inflicts 17,100 to 18,900 (Heroic: 19,000 to 21,000) Shadow damage.
Stone Grip: Grabs 1-3 targets, incapacitating them and inflicting 3,700 to 4,300 (Heroic: 5,363 to 5,637) Physical damage every 1 second, until they are freed. The Arm can sustain 100,000 (Heroic: 480,000) damage before it releases its targets.
Once you have added these debuffs to Grid, be sure to click on them and ensure they’re enabled. You’ll also want to set their priority so that other settings don’t obscure them. (For example, I have these “oh shit” debuffs set as a higher priority than the PW:S or DA icons).
Finally, you need to determine where on your unit frames you want these debuffs to appear. For me, it’s most noticeable if they show up as center icons.
How and if you choose to assign healers to those who end up in Ignis’s pot or Kologarn’s grip is dependent largely on your raid composition. But I would encourage all healers, regardless of whether or not you’re typically the one who handles this, to activate these debuffs on your unit frames.
