When I found out that the experience and leveling coming in 1.8 would not have a use until later, I was pretty disappointed. And now it seems like vanilla skills won’t be coming until 1.10. So I decided to take matters into my own hands and make the Level Up! mod. What this mod does is add 12 (as of now) skills to the game, which you can increase using skill points gained from leveling up (you get 3 per level up).
1) Install ModLoader (important that you do this first)
2) Extract the files from the “classes” folder in the .zip and then drag them to your minecraft.jar
3) If you want to use Zombe’s mods, consult the readme for further instructions
4) Be sure to delete the META-INF folder if you haven’t already
