Obese (3.5e Flaw)
From D&D Wiki
Let's just say you enjoy a good feast. Ten times a day.
Prerequisite: Dex 14 or lower (if the dexterity score rises afterwards, the benefits and detriments of this flaw still apply)
Detriment: An obese character is double the weight rolled on the random height and weight tables. This seriously affects their abilities to do physical tasks.
The character gets a -4 armor check penalty that stacks with all other armor check penalties. They also count as always wearing heavy armor with at least a medium load for purposes of movement and fatigue.
Benefit: Bonus Feat
