Seal of the Martyr

Seal of the Martyr allowed a Paladin to deal a large amount of Holy damage with every strike, but had a backlash effect which would damage the Paladin. It was possible for Paladins to kill themselves when using Seal of the Martyr which probably lead to its removal from the game in patch 3.2.0.

Seal of Blood is the Horde version of this spell.
