I don't understand what you mean by "+1s the skill level down by the difficulty". The "+1s" bit sounds like addition but the "down by" sounds like subtraction so I'm confused by what you're saying. As in, the skill level is increased by one and then downed by the diff - ... What? I genuinely have no idea how to understand what you're trying to say.

And even if I got them both to level 4, level 5 should be the cap at Character Level 60 but I still can't go up any further so that doesn't make sense either way.
