Elys' uncapper doesn't work like other +100 mods. It doesn't hold you to below 100 and then add bonuses to make up the difference. It changes the games internal settings to allow you to go up to 200. So you should continue to go up 100, 101, 102...200 with any item or magic bonuses on top of those.
I understand, I've used the player.setav blade command to change it to 0 just to test, and I was left with the above 100 bonuses only, wich was 13 green points, but what i'm not understanding is that, my blade skill before that was 115, so my skill was 102 + 13 bonuses wich, I believe the 13 points is due elys's mod running, but in any case, how could my blade skill go 102 after all? wasnt supposed to go up to 100 and then only bonuses gets applied? there's also some other skils that 101 + bonueses as stated, and I can se those because I'm using darnui, I might be all wrong, or either everything is fine, it is just not showing correctly, the fact is that I used legendary mastery before, and I'm afraid I've messed up something.
