Blood Rage

Centuries ago, ravaging bands of Marauders swept across Oriath, and nearly toppled the monarchy in the capital. Before they met the order's Templars on the battlefield, they chewed the sacred root, and entered the 'Blood Rage'. Under the influence of the Rage, the Marauders knew no fear or pain, and every blow they struck on their enemies rejuvenated their depleted life. The root also drove the Marauders half-crazy with blood lust, causing them to attack with blinding speed as long as there was flesh nearby to hack. The only consequence of the Blood Rage state was a gradual loss of the Marauder's blood, but the magical invigoration from attacking was usually enough to compensate.

Description on the official Path of Exile website

Blood Rage applies a buff that deals physical damage to the player over time, while increasing attack speed and life leech. Killing an enemy while this buff is active refreshes the buff duration, and has a chance to grant a frenzy charge.

Skill Interactions

Physical damage reduction: Damage dealt by Blood Rage is lowered by physical damage reduction. Note that armour only reduces physical damage from hits, and thus does not affect the damage taken from Blood Rage.
