Small concept for a new ap jungle item.

Magus enchant (name opt to change) Recipe Haunting Guise + smite enchant Stats +45 ability power +300 hp +15 magic penetration Unique passive Eyes of Pain Dealing spell damage or auto attack damage applies a damage-over-time effect that deals bonus magic damage equal to 1% of the target's current health per second for 3 seconds that gives mana based on 5% damage delt. This bonus damage is doubled against monsters and capped at 250 damage per second vs. monsters. PROS Gives mana sustain for long battles. Gives magic pen an tankiness a lot of the good stats ap junglers have wanted for a long time. Jungle clears and takeing objective speeds would be increased by this item. The final and most important part on paper it seems it would not be abuised by lainers since they would just see a crappier Liandrys with decent mana sustain. What junglers see an item that gives them better clears for more ganks/to catch up if fallen behind and better objective speeds. CONS No cooldown reduction :c can't win them all I guess. Could be to fast on taking objectives. What do you think of this item would it be incredibly broken or under powered? Do you have a name for this enchant? Comment below!
