Savagery (Skill)

''The heat of battle rouses savage animal impulses within you that heighten your aggression and empower you with nature's fury. When used as your default weapon attack, Savagery increases the intensity of your attacks with every strike.''

Building up charges increases the potency of the bonuses.

Charge bonuses
With this skill, every attack adds a "charge" to a character, up to 6-9 according to skill level. A single charge is subtracted every two seconds you go without using Savagery, down to zero. Charges are gained so long as the game calculates an attack roll-- "Miss" and "Block" will grant charges, but whiffs will not (destructibles will grant charges if the character actually uses Savagery instead of kicking the item).

The number of charges determines what portion of the flat lightning and bleeding damage will be added to your attacks with Savagery, and do not apply to any other bonuses to Savagery. All other bonuses to Savagery are added in full from the first charge and persist until the last charge is lost. E.g. A character with zero charges of level 2 Savagery will deal 104% weapon damage on every hit of Savagery in addition to the lightning and bleeding damage.
