The values are for everyone to get a general scale, the numbers on Bosses aren't for calculation so much, as they are for allowing the player's to realize the scale difference. Muriel could do immense damage to a non-blocking armored character, and likely kill a lightly armored one with ease. I am giving everyone the chance to be reasonable with their characters, and then after this if I have to I will get technical with the calculations for the rest of the bosses if people have trouble being reasonable, but I doubt that will happen. 

Note: No one is to post an actual numerical representation of damage to Muriel, I will be adjusting her Health Bar with each Boss post I make for her and future bosses.
