I've done Grobbulus quite some times now. Key is to keep dps up. The rate at which the injections come are -TIME- based and not HP based like most are lead to believe.

The higher the dps, the faster the kill, the easier it is to multibox.

Ending his life in under 5 minutes will make it easy, somewhere around 6 minutes into the fight things start getting a bit complicated and after seven minutes all hell breaks loose. (My fastest kill is 2 minutes and 45 seconds with four of my shamans present now and he's piss easy then. :P )

Here's a tip tho, have DBM installed on all characters and a "/cast [target=player] Cure Disease" on all four (not broadcasted). When one gets the injection, run immidiatly and when far enough away, quickly cure the injection and run back. This will minimixe the time your injected shaman will be away from the raid and will help in DPS but also in the case of getting two injections or more in a row. Which this trick I've had as much as 10 injections in a row without breaking a sweat upto around 4-5 minutes into the fight.


Thaddius 10 man, have everyone in the raid spread out 10 yards, don't bother combining charges, just tank and spank him while spread out. We kill him this way with 3-4 minutes left before enrage. Any group should be able to kill him ten man this way. And you'll get the achievement too. :>

My main also has the red proto drake now, going to work on getting it on my alts too. I usually do heroics with friends and guildies so not always bring all 4. ;(

My guild is working on S2d now and Malygos. We haven't tried Malygos much yet tho, we're semi casual and usually only raid 2/3 evenings a week, which is often just enough to do the other 10 mans. :/ But with focus follow on drakes I should be able to handle myself there as well.
