7-9 healers
Usual mix of DPS (ranged preferred)
All raid members take 8,500 frost damage every 60 seconds, making 8,501 HP buffed the absolute minimum requirement, but in practice 10,000 HP buffed are needed, to give the healers a little slack Rogues need to keep a full stack of Wound Poison up on the boss to reduce its self-healing effect Tidal Shield
Every 60 seconds (the first time 60 seconds after the pull), Naj'entus casts a Tidal Shield (instead of throwing an impaling spine). He stops throwing needle spines for 10 seconds after casting the shield, but continues to melee. The shield can be broken by throwing an impaling spine looted earlier at it.
Since the shield deals 8500 frost damage to the entire raid, everybody must be at top health before the spine is thrown. Most Boss Mod type UI enhancements have an indicator window showing people with less than 8500 health when the shield is up.
Dealing with the Impaling Spines and the Tidal Shield requires good synchronisation. It's a common practise to have one player announce the Impaling Spine targets, and to call for the throwing of a spine when the whole raid is healed. It's a good idea to have one of the raid healers do the calling for the spine throw (because he can call for the spine when the last heal is nearly finished).
In some situations it may be necessary to sacrifice a few raid members because Naj'entus heals himself, so waiting a long time for the raid to heal up is not a good option. Macros
This is a quick method to throw a spine from the inventory:
/use Naj'entus spine
It's also a good idea to announce the facts of being hit by and having looted a spine:
/say <name> got spined!
and
/say <name> looted a spine!

Impaling Spine
Every 20 seconds, Naj'entus shoots a large coral cone at a random raid member. The spine paralyzes and damages its target until it is removed by another player by looting the target. This needs to be done very quickly. It is possible to carry up to five spines in the inventory.
Looted spines disappear when releasing (after a death) or when the encounter is reset.
