Here is my take on leveling. I quite like the original system where each vocation has its own attribute growth, but I find that after level 25 or so the character becomes too overpowered for the main game. This mod aims to address this issue.

I have redone vocation leveling tables - tables that govern how fast attributes increase with each level for each vocation, as described in this Wiki page. In the original, there is a strong growth between levels 10 and 100, then growth slows after level 100. In my version, I brought that breakpoint all the way down from level 100 to level 20-30, depending on vocation. I have also significantly reduced attribute growth past that breakpoint, and almost removed magic increase for strider, ranger and assassin since they don't use magic. Please download the spreadsheet from the Files section for full details.

In my game I combine this leveling with the slow leveling curve "Plateau" from Alternate EXP Tables. Version 1.1 of this mod adds this XP leveling curve, as well as my own vocation rank leveling curves that are slowed down accordingly. You will still have the same amount of discipline points, but higher level skills will not become available until you reach the appropriate rank. Ideally the cost of each skill should also be increased, but I wasn't able to find where it is done. You will therefore have more points than you know what to do with. :)

This leveling system will probably result in a character that is too weak to take on the Bitterblack Isle past the gazer, but the purpose of it was to keep the main game engaging. You level up, your attributes grow, but they don't grow at such breakneck speeds and do not make you into a living god. A cyclops is still bad news, even on higher levels, and the drake in Devilfire Grove will still present a very big challenge. With such leveling, skills, augments, armour and weapons become much more important.

Normally, a mod such as this one requires a new game. However, you can backport your Arisen and your Main Pawn to the new system by editing their attributes with Dinput8 Hooks. Use the spreadsheet from the Files section to calculate the correct values for your level. Of course, they won't be the exact values you would have had if you used this mod from the start because they are based on a single vocation. However, they will be close enough, and will allow you to continue the game without being overpowered. That's what I did in my game at level 33 (a cyclops should really take longer than 10 seconds to kill).

I have uploaded two versions of this mod: a copy-paste version of the game_main.arc file and a version for merging that contains individual files that I modified. Note that the copy-paste version is completely clean otherwise, there are no stamina changes, no run speed or carry weight changes, or anything else that you often find bundled with this type of mod.

To install the copy-paste version, navigate to your nativePC\rom folder in the game installation directory, make a backup of your existing game_main.arc file and then paste the one from this mod into that folder.

To merge this mod with another one, you need ARCtool, and I assume you know what you are doing!
