Moons of Peril repair

Blood Moon, Blue Moon and Eclipse Moon armour breaks after about 45 hours of combat and sells for less broken. Repairing a piece costs 1,500,000 gp at an NPC, or less at an armour stand in your own house: every Smithing level takes off 7,500 gp. The weapons never break. Prices assume you buy and sell instantly, so these profits are the safe floor; with offers you earn more.
