Amulet of blood fury
The amulet of blood fury is an amulet of fury temporarily enhanced with a blood shard, granting a passive chance for life leech on melee attacks. When dealing melee damage, the amulet grants a passive 20% chance to heal 30% of the damage dealt on any hit. On average, players will heal for roughly 6% of the melee damage they deal.
Depending on the opponent's Defence, with a four tick weapon (such as the abyssal whip or a Ghrazi rapier), one shard will last for approximately seven hours of sustained combat before depleting; with a five tick weapon (such as a leaf-bladed battleaxe), one shard will last approximately eight and a half hours.
When killed by another player and the amulet of blood fury is not one of the items protected on death, the amulet is converted to a normal amulet of fury; the blood shard and any remaining charges are lost.
