This mod takes the NewScale experience values from the UnlockLevelCurve mod and changes them to faster leveling rates: [x1.1, x1.15, x1.2, x1.25, x1.33, x1.5, x1.66, x1.75, x2].

ORIGINAL MOD: UnlockLevelCurve - Level 13-20

The main file of the original mod is a requirement, and I strongly suggest you look through the original mod's description before downloading any of these. They function identically (save for the exact numbers) to the optional patch mods in that listing. Use the same load order.
Same as mentioned there, altering the exp curve on an existing save file is not recommended; and may result in glitches such as unexplained discrepancies between party members.

x1.33 has been playtested through about half of Act 1 and works perfectly so far. The rest have had their numbers double-checked while copying from a sheets/excel document but have not been tested in-game. Let me know if anything seems wrong.
