Modifiers to the Effect of Buffs or Debuffs usually come from the target it affects and are multiplicative with modifiers to the Magnitudes of the Buff or Debuff, which come from its creator.
Mark a target, making them more susceptible to being Shocked. When the Marked target dies, a Lightning explosion erupts from their corpse. This explosion does not use your Weapon Damage, and instead uses its own base Attack Damage.
Place into an empty Rune Socket in a Body Armour to apply its effect to that item. Once socketed it cannot be retrieved but can be replaced by other socketable items.
