ArmorSet bonus
(1 item) Killing an enemy grants you a stack of Sload's Call for 1 hour, up to a maximum of 50 stacks. Each stack increases your Weapon and Spell Damage by 23, reduces your Maximum Health by 120, and reduces effectiveness of your damage shields by 1%.
Sload's Call is lost if you remove Thrassian Stranglers, go invisible, or crouch.
