Flame Leviathan:
- [Firestrider Chestguard]
- [Combustion Bracers]
- [Lifespark Visage]
- [Energy Siphon]
- [Handguards of Potent Cures] - [Hard Mode]
- [Shimmering Seal] - [Hard Mode]
Ignis:
Razorscale:
- [Binding of the Dragon Matriarch]
- [Eye of the Broodmother] - Notes: This is an interesting one. Similar in essence to the [Illustration of the Dragon Soul], except with less of a SP bonus and a ton of crit. Less stacking (x5) means it will be fully charged more than its counterpart, and the constant crit is a nice bonus to have. This piece will be hotly contested, make sure you try and get your hands on it. A good replacement for those of you still sporting the Sundial.
- [Ironscale Leggings]
XT:
- [Conductive Cord]
- [Helm of Veiled Energies]
- [Plasma Foil] - Notes: This is a very popular caster piece, from what I am seeing. An upgrade from the [Wraith Strike] in my opinion, but the spirit makes it a little bit bittersweet. Judge this one for yourself.
- [Pulsing Spellshield] - Notes: I have a funny story about this one. First week I ran Ulduar 10 I saw this drop, and I was with a holy pally and resto sham. We all kind of looked at each other, as the OLD stats showed only 37 SP and we kind of concluded with that much stam it was a PvP piece. They have subsequently changed it to 73 SP and I am now kicking myself for letting the resto guy walk away with it! I am now hunting this one to replace my plastic-looking piece of crap...
- [Vest of the Glowing Cresent]
- [Breastplate of the Stoneshaper] - [Hard]
Assembly of Iron:
- [Belt of the Iron Servant]
- [Boots of the Petrified Forest]
- [Lady Maye's Sapphire Ring]
- [Runetouch Handwraps]
- [Stormtip] - Notes: Similar to the Plasma Foil (above).
- [Belt of the Crystal Tree] - [Hard]
- [Watchful Eye] - [Hard] Notes: Different from the Watchful Eye from Naxx...
Kologarn:
Auriaya:
- [Cover of the Keepers]
- [Elemental Focus Stone] - Notes: An ungodly amount of hit with a proc that is not to be laughed at either, a fantastic upgrade if you are still using the Mark because you weren't lucky in Naxx to get [Dying Curse].
- [Mantle of the Preserver]
- [Raiments of the Corrupted]
Freya:
- [Gloves of the Wayward Protector], becoming [Valorous Worldbreaker Gloves]
- [Unraveling Reach]
- [Fire Orchid Signet] - [Hard]

General Vesax:
- [Bindings of the Depths]
- [Pendant of Endless Despair]
- [Underworld Mantle]
- [Vestments of the Piercing Light]
- [Aesuga, Hand of the Ardent Champion] - [Hard] Notes: Very, very cool mace. As well-itemized weapons are seeming to be very scarce for us in Ulduar, this is one of the best out there. Disgusting amounts of spell power and a yellow socket make this thing beastly.
- [Leggings of Profound Darkness] - [Hard]

- [Devotion]

This is difficult to do, as there is still new items being discovered off this guy every week (Thanks Ensidia!). WoWWiki has a good loot table that is being updated as stuff becomes available, and MMOChamp usually posts new discoveries. I will update this at a later date to reflect when we are more confident everything has been discovered. If you are killing this guy I am surprised you are reading my blog because this is beyond what I am doing!
Hope you get something out of this guide. Again, sorry for the lack of posts recently.

Edit (July 2, 2009): Mainly cosmetic, added appropriate Epic colours and square brackets. Added Algalon loot table. Removed unnecessary commentary. Added notes in place of commentary where I deemed necessary. Minor spelling corrections.
