Hellou to you all, since I haven't found a particular mod that makes the changes that I want, I made this mode for myself and I wanted to share it.

This mod makes a few things:

1 - Makes it so all the skills can be used in all of the 4/(1-4) positions.
2 - Makes the skill more powerful wheather that's from bigger numbers or added targets.
3 - Makes the heroes stats stronger, specially at high levels.
4 - Makes the heroes resistances higher.
5 - Makes each class a specific monster slayer bonus on all his skills (ex: The Crusader is an Unholy Killer and the Shieldbreaker an Eldritch Killer.).
6 - Makes each class fit into a role or a class and then each class has one or two unique "atributes" or roles (ex: the Abomination, Hellion and the Leper heroes has stats and skill numbers "designed" to deal lots of damage and  the Hellion has a very powerful stun skill.).
7 - Makes so that all and each of the classes has a full party healing skill that also buffes damage.
8 - Makes so that all and each of the classes has a "slayer" or "monster type buff damage" attribute in all of their damage skills.
9 - Makes so that all and each of the classses has a skill that stun one or various enemies (with some exceptions).
10 - Makes so that all the skills cannot move the enemies. The "Pull" or the "Push" on the skills is/gets removed.

I will put an article into each class and here I will try to make some generalized explenations.

INSTALLATION
Unzip and Replace the contents on the zip to the main folder of the game, where all the folders are there. Making a backup of the changed folders is recomended. In my case it's: "F:\Vydiagames Folder\Steam\steamapps\common\DarkestDungeon"
