I could try to make it give mana regen before completing it, but then what would it build from? Forbidden Idol? That's 600 gold that's not spent on damage. I feel like there would be more cons than pros. I also could do something like Brutalizer+Soul Sickle=Essence Reaver, with Sickle granting AD, lifesteal and mana regen (Scepter+ 2 Faerie Charms maybe?), but then Reaver would have to grant less than 80 AD (Riot said they want 80 AD items to be built from a B.F. Sword). Also, nothing would stop melee casters from buying it since they wouldn't lose anything (unless I give lifesteal and mana regen as a ranged-only passive on both Sickle and Reaver, but I don't know how good it would be to lose stats on buy, even if only for melees).
