Athene's "Unlucky" Unholy Grail

This item used to be the bread and butter of mid laners back in the day. But this rework of mage items were nice; I do not deny this. However, a proposition must be made in order to rebirth this very "Unlucky" Unholy Grail.

To put it simply as possible, the item has little to none use in any game due to it's very weak skill. It is meant to be a support item, that's fine. It has became a cool concept to play around with mana regen to gain AP; once again that is fine.

But the main issue it the main skill itself. It provides a 250 heal at level 18 since it scales by level. And to top it off, it can only heal allies and not the user.

Now I've always loved blood mages; who doesn't love a little blood bending, right? But I don't mean blood mage as in Vlad; just no. I've always loved the idea that any mage can become a blood mage if it has been well thought out. And this item should provide mages (at least the one with heals/shields) with that ability.

The fix/buff of all of this should be a simple AP ratio with the heal and allow the blood charges to heal the user itself. Let's make this once glorious item once again GLORIOUS. That's all. Thank you.
