Fills the Paladin with holy power, causing attacks to apply Blood Corruption, which deals [(0.013 * SPH + 0.025 * AP) * 5] additional Holy damage over 15 sec. Once stacked to 5 times, each of the Paladins attacks also deals 33% weapon damage as additional Holy damage. Blood Corruption can stack up to 5 times. Only one Seal can be active on the Paladin at any one time. Lasts 30 min.

Unleashing this Seal's energy will deal [1 + 0.22 * SPH + 0.14 * AP] Holy damage to an enemy, increased by 10% for each application of Blood Corruption on the target.

BUG: Debuff from Seal of Corruption is replaced by debuff from Righteous Vengeance. Righteous Vengeance disappears aftger next paladin melee hit.
