I'm sending this for my friend Hellboy. Usually in Atlantis when hitting Poseidon he does around 20 Million damage per turn, 200 Million per round. A little while earlier he noticed that when he hit the damage kept going. He finally ran away around the 800 Million mark. The next turn started doing the same. He is using maxed Huntress as his ally.
He wants to make sure the devs are aware of this, and to make sure it is fixed asap.
