The Save DC for the detect hidden right now is based on the defender INT instead of his DEX, my Elf has +2 DEX but the save to detect him is made vs a DC of 8 (10 -2 from his INT) instead of 12 (10 +2 from his DEX). And my rolls to hide in battle are being made with the INT modifier (-2) instead of the +2 (DEX) the only Hide roll that is using the DEX bonus is the one before battle with the "Shadowy" Talent
