Ok it might be the mod to increase difficulty

@L'égocentrique I just loaded the mod up in the engine, 2 old saves, and a new save with all showing the skill only requires rank 1 scoundrel.

Why does it make adrenaline require scoundrel 7?

Yeah, it might have been that they had a skill on them modified by the mod. Definitely possible

well that's weird, if you did nothing to daggers, unless the daggers themselves had skills on them, they shouldnt have been removed

As well daggers and poison have nothing to do with this.

Some other mod you've got must be messing with daggers as this one isn't touching any of that data for what it does.

I'm working on fixing the names. Due to the way localization works, some of the names in engine for skills aren't actually reflective of the real ones, so I'll fix those before tomorrow. The || is also due to localization and translations.

As far as the daggers being removed, that's all how the engine handles it. I did nothing to the equipment slots, daggers, or weapons at all for this mod. All I did was change the numerics and statuses on skills.

I've been playing with this for a while and it's changes are pretty cool. However I found that daggers were no longer able to be combined with poison, backlash was changed to "vault", throwing knife had || surrounding the name and descripton. When I tried to remove the mod my daggers were also removed from my character.
