Basically what I would like to achieve in my mod is as follows;

When you reach the maximum skill level with a certain skill you have the option to "specialise" into that skill and raise that one skills limit by another 50 points. However that only applies to that skill and you can only choose one skill in total.

There will be a few knew perks that can only be reached from a specialised skill and will remain locked for all other skills.

I am slightly stuck however, as I cannot for the life of me find a papyrus command to change a single skill limit and as such I am quite stumped as well as the papyrus script to detect a skill level increasing.

If any of you have an idea of what my papyrus script should look like please post it as I need all the help I can get with this one, or if any of you have a different idea of how to do this that would also be greatly appreciated.

Many thanks
