New item "Siphoning Chains"

Siphoning Chains

700 Health 100% Base Health Regen 40% Attack Speed

Unique Passive : Auto attacks siphon 3 health per attack from yourself (3 second cooldown). For each point of health siphoned, your champion gains that much health in maximum hp (up to a maximum of 300 bonus health)

Unique Passive (Toggle) : Toggle on to cause each auto attack to siphon 1% of your maximum hp but you deal a bonus 2% of your maximum hp in damage.

Basically this just gives straight up tanks at least SOME dueling power later in the game. Because it works with % hp its basically only a tank item and would not turn tanks early game into great duelers.
