KMST 1.2.479 Translated Skill Change Patch Notes

For the case of Ordinary Magic Guard and Bless of Darkness's damage reductions, Bless of Darkness's damage reduction is calculated first now. (I don't know how this would matter).

I don't know what Blessing of Darkness does, but my guess is that by letting its damage reduction happen first, you lose less MP from Magic Guard's damage reduction ability.
