IGN has declared
that the 'Madness Armour' featured in the Oblivion expansion The Shivering Isles is one of the 25 best armour sets in games.
The Madness Armor is a heavy armor set that you get through taking on the Antipodean Hammer quest. Once you have enough Madness Ore bring it to Cutter at Cutter's Weapons in Bliss and she will make you a piece of the armor. Boots cost two pieces of ore, as do the helmet, shield and gauntlets. The greaves need three to be crafted, and the cuirass five.
The Madness Armor not only adds scarily good bonuses to your character it also looks, well, mad. There's a face with sharp teeth engraved into the breastplate, mini faces on the knees and a multi-eyed, pointy tooth face on the shield.
Oblivion Nexus is glad it doesn't have to make up lists like this to fill news posts.
