I checked the Evil System Shop.

❼ Staff of Endless Mana
A meter-long fragmented staff, connected with invisible threads of Magic. It is made of concentrated mana and is weightless. A small mana core floats among the headpieces that serve as a center point, producing constant faint vibration.
As long as you equip this staff, you'll acquire +1000 MP and +100 INT.
Equipping this staff would reduce mana consumption by 10% while recovering 10% MP every one minute.
WARNING!
If your MP reached zero, this staff would use your HP as compensation if you used mana-related abilities.
Cost: 50 000 Evil Points

By the way, System, I said it to my mind as I went back to town. Could I simultaneously equip Lucy and this staff?
Really? I thought I needed to have some kind of skill for that.
