Attribute - Vampirism

Vampirism is a health-drain attribute in Like a Boss. It is closely linked to Health and Regeneration as it affects the total Health attribute of a Boss through various means. The base Vampirism value for a boss can be increased through passive skills, active skills and accessories throughout the game.

Vampirism has a "Rating" that influences the total percentage of health restored by each attack based upon your BossLevel Rating. The formula is as follows:

Rating / ((Rating + (BossLevel * 80)) * 25) = Percentage Drain

What this means is that Vampirism converts a percentage of the damage dealt back into health for your Boss. For example, if you have a base Vampirism stat of 1000 at Level 50 the formula would convert to the following:

1000 / ((1000 + (50 * 80)) * 25) = 0.8% Health Converted

Displaying this from an offensive play standpoint, if you were to deal 3000 damage in a single attack with 1000 Vampirism and a Level 50 boss you would gain back 24hp from that attack.
