I don't know why I took this long to ask, but I am asking now since it matters when fighting monsters at a higher level than me. When doing damage calculations, the way that the game rounds off the numbers is inconsistent. This is what I have learned since playing the alpha and beta versions of the game.

When calculating the bonus damage, the result is rounded down. When calculating damage resistance it goes up or down depending on the one who has the resistance. Can anyone verify if this is correct and tell me more about how the game rounds the numbers in the game.
