Bastion the Avenger is my nemesis

Combo attack devestate to 50% Current hp instead of max hp. Drop Nora.

 

Downside of this though is that after 2 attacks most champs would only have 10-20 hp anyway.

 

Yep.

Or you could just have the dang thing make a third attack and avoid all this 50% crud.

That way you could still get good returns from it but requires more then just double tap destroy.
