First, I have screen shots, but I can't upload them here. After multiple tests, I have narrowed down that before any empowers ever hit the field Chrysos' Thunder Spike debuff is now hitting for 3,696,000 damage.
Yes, one hit of 3.7 million in damage.
Of course, you die and the Thunder Spike explodes for the normal 160K damage. But an initial 3.7 million in damage? It's just crazy. No one can defend against that. Folks in our alliance report it's like he's fully empowered but this is how hard he's hitting from the start.
