He cant have a instant kill Aoe that hits for more than the max health of your character. He also cant cast the thing every 8 secs. There are just not enough stuns and interrupts. He has killed me more than 50 times and has cost a fortune to repair.
I say take away the 31k health he has.
Take out the voice stuff make it a 60 sec cd or something.
The red lightning ok he can have that if the rest of this guy is lowered.
