What to Wear: A Shadow Priest’s Guide to 25-man Icecrown Citadel Gear

As previously noted, I'm not a math geek so I am not going to argue BiS (best in Slot) with the maths here. Rather, I am going to discuss your gearing up opportunities by boss, to help you prep your wish list. If you want to see BiS across all available 10-man and 25-man raids, including ICC hard mode boss drops, shadowpriest.com has an excellent list. With more math than you can shake a stick at.

Words of Caution: As with ToC, you will want to be picking up some haste gear from ICC which means doing the hit-swapping dance, so don't be quick to shard or sell your existing gear when you receive an upgrade. You will likely have to swap gear around for raids to ensure you stay hit capped.

Your boss-by-boss gear guide, after the jump.

The Lower Spire

Lord Marrowgar

• Bone Sentinel's Amulet(264). Your first crack at a neck upgrade.
• Crushing Coldwraith Belt(264). Your best upgrade unless you are doing hard modes.
• Marrowgar's Frigid Eye(264). This is intended for healers, but if you've had terrible luck and the healers already have it, this could be an upgrade for much of what was previously available for this slot.
• Frozen Bonespike(264). Your best main hand weapon upgrade unless you are doing hard modes. The next best option after this is the Hammer of Purified Flame from the Quel'Delar quest chain.

Lady Deathwhisper

• Shoulders of Mercy Killing(264). Good upgrade if you use hit in this slot.
• The Lady's Brittle Bracers(264). Your best upgrade if you use hit in this slot. Not an improvement over the crafted Bejeweled Wizard's Bracer / Bejeweled Wizard's Bracers.
• Ring of Maddening Whispers(264). Itemized better for healers, but still a solid upgrade.
• Nibelung(264). Good upgrade if you don't have a hard mode staff of some flavor, and minor upgrade to ToC 10's Enlightenment(232) / Illumination(232), with a fun proc (Equip: Your harmful spells have a chance to cause you to summon a Val'kyr to fight by your side for 30 sec.)

Gunship Battle

• Corp'rethar Ceremonial Crown(264). This is your easiest helm upgrade, bettered only with the Conqueror's Mark of Sanctification improved Tier 10 helm or by doing hard modes.
• Amulet of the Silent Eulogy(264). Good upgrade if you use hit in this slot.
• Gunship Captain's Mittens(264). Good upgrade if you use hit in this slot.
• Ring of Rapid Ascent(264). Your best drop for this slot, improved only by the Exalted version of the Ashen Verdict ring, or by doing hard modes.

Deathbringer Saurfang

• Greatcloak of the Turned Champion(264). Solid cloak upgrade, and better than the emblem of frost cloak.

The Plague Works

Festergut

• Holiday's Grace(264). This is intended for healers, but if you've had terrible luck and the healers already have it, this would be an upgrade for much of what was previously available for this slot.
• Lingering Illness(264). Itemized better for healers, but this belt is still a solid upgrade.
• Plaguebringer's Stained Pants(264). Decent upgrade if you use hit in this slot, but both tailored legs are better for you otherwise.
• Plague Scientist's Boots(264). Your best in slot for your feet, second only to the hard mode version.

Rotface

•  Death Surgeon's Sleeves(264). Your best in slot for your wrists, second only to the hard mode version.
• Trauma(264). With its healing proc, this is clearly a healer mace, however, if you've had terrible luck and the healers already have it, this would be an upgrade for much of what was previously available for this slot.
• Corpse-Impaling Spike(264). Your best wand upgrade unless you are doing hard modes.
• Dislodged Foreign Object. Theorized to be the best in slot trinket due to its proc, but may take some time to see how it pans out.

Professor Putricide

• Nothing for shadow priests here.

The Crimson Hall

Blood Princes

• Sanguine Silk Robes(264). Your best chest drop in the instance, bettered only with the Conqueror's Mark of Sanctification improved Tier 10 chests, the Frost Emblems chest, or by doing hard modes.
• San'layn Ritualist Gloves(264). Your best glove drop in the instance, bettered only by the Frost Emblems Gloves of False Gestures, or by doing hard modes.
• Valanar's Other Signet Ring(264). Decent upgrade if you use hit in this slot.
• Shadow Silk Spindle(264). Your best off-hand weapon unless you are doing hard modes.

Blood-Queen Lana'thel

• Blood Queen's Crimson Choker(264). Your best neck upgrade unless you are doing hard modes.
• Dying Light(264). Your best staff upgrade unless you are doing hard modes.

Frostwing Halls

Valithria Dreamwalker

• Frostbinder's Shredded Cape(2640. Your best cloak upgrade unless you are doing hard modes.
• Robe of the Waking Nightmare(264). This hit chest is unlikely to be an upgrade unless you did not obtain your Tier 9/Triumph badge chest.
• Nightmare Ender(264). This wand is itemized a bit better for healers, but still a solid upgrade.

Sindragosa

• Memory of Malygos(264). This ring is itemized better for healers, but still a solid upgrade.
• Sundial of Eternal Dusk(264). This off-hand weapon is itemized a bit better for healers, but still a solid upgrade.

The Frozen Throne

The Lich King

Loot tables TBD.

Trash Drops

• Stiffened Corpse Shoulderpad. Your best non-tier shoulders unless you are doing hard modes.
