If Moleman is bugged, then so is crovus... need to buff Corvus to match his description
According to Corvus's glave charges... if you do lethal damage to him, and he has charges... you remove the charges instead of dying. Only
So let's assume no DOT or other "effect damage is ticking down". Corvus has 20 charges... and if you kick him down via a heavy attack (only doing white or yellow numbers), those charges should be expended... he should remain at 1 life... and only then hit the ground and lose his glave immunity. He should not be die yet... as no damage would have been taken to lower his life from 1-0 while he was on the ground.
Since it is paramount that the description of powerful ability match how the champion performs, then Corvus needs to be fixed to keep him alive until he takes more damage (before glave comes back up).
