Hello,
as more heros don't have mana, Maybe change the drone to something like draining 2,5% of secondary resource? Then it would work against Khai and Eden too and would have some value.

carmine breach
fervent phoenix
We also have mana drain items with heroes with no mana existing which doesn't make sense
fossil basin
personally I think she should have counter picks like that. mana drain in itself is strong it doesnt need to do it to all types of heroes.
carmine breach
And her Ult is another thing to address here.
When playing against heros without mana its only doing min dmg.
So a Khaimera doesn't even care to face me with 2 abilites only doing half the things they should.
