Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - General So.. What happens after you beat the game?|

I'm nowhere near endgame, but I've still found a small handful of Level 20 items (due to a few oddball drop areas that drop incorrectly scaled gear). Level 20 Plate Armor and Shields appear to require 14-15 Strength, and a Level 20 Dagger that I found requires 14 Dexterity.

From that, I'm going to guess that most item requirements will cap out at about 15.
