The mana cost was extremly high to compensate for the over-powered buff. Since she has a lot "starting/passive" boosts, if you want to keep the buff going you'll have to sacrifice an offensive/defensive item to get extra mana or mana regeneration. I did not want a flat value because I thought it would be better for teammates, in case you wanted to build her a little bit more defensive (A flat damage bonus PLUS her already high passives would end up in maybe way too much damaged unbuffed). Ty for commenting ando offering help! It's really appreciated! :)
