Loatheb

[Sword_of_Doom]

Very interesting fight in Naxx. Basically he has about 5 million hp and has a number of abilities. Copied from WoWwiki.

Attacks and Abilities
Loatheb has around 5,330,000 HP
Corrupted mind Loatheb places a 1 minute linked cooldown on all healing spells, including cleanse/dispell/depoison. This means you only get 1 healing spell to cast per 1 minute, including cleanse/dispell/depoison. Anything that heals, removes a debuff, or otherwise prevents dmg on others (PWS) pretty much is affected
Poison Aura melee range. 196 Nature damage inflicted every 6 sec in 10 yards. 12 seconds duration.
Inevitable Doom Loatheb begin to cast it after 2 mins in fight. Inflicts 2550 Shadow damage after 10 sec. 100 yards, every 30 secs. 5 mins after engaging, this will be every 15 secs.
Fungal Bloom Critical-hit chance increased by 50%. Spell critical-hit chance increased by 60%. Spells and abilities cause no threat. Get from envionment, you can control who gets it. 90 secs duration, every time only 5 people can get it.

We had our first night of full attempts on him and got him to about 50% or so with no buffs or pots. We die out usually after the second doom. I am well aware that buffing and potting are necessary for this fight but we wanted to make sure our healing strat/rotation and DPS were on par with killing him. No point in wasting the consumables that are needed for this fight without certainty of killing him.

Some questions:
Ideally you probably want to kill him before 5 minutes right? After that dooms are every 15 seconds or so making it impossible for the raid to outheal the damage.

Secondly, are all world buffs necessary for this fight (like Dire Maul, Hakkar, Dark Moon Faire etc.)?? Our guildleader would like us to take the couple of hours to do that and than one shot Loatheb. Personally i think thats not necessary but having not killed him yet thats not a very convincing argument. For those of the Lurkers that have beat this fight, did you use all available world buffs on your first kill?

Thirdly, is it necessary to have more than 5100 hp for this fight, considering you could survive two dooms (or a minute of fight time)?? I am thinking its a good idea but there was some resistance from the raid to do that.

Essentially you are looking at taking 15, 300 damage over the course of the fight and nobody can heal you but yourself.

Some thoughts on this fight would be nice:)
