Flaw - Obese

You are large, slow, and heavy.  You weigh +50% or more than others of your kind.  Armor must be custom made for you, costing twice the normal cost.  Your movement speed is reduced by 10, and you have disadvantage on Strength (Athletic) ability checks, and when rolling for exhaustion.

FLAW. This is a flaw feat. At your DM's discretion, you may take this feat at level 1.  If you do, you may also gain a second feat, or increase two of your ability scores by +1 (or one by +2).  If you choose to increase any scores, you cannot choose to increase any score affected by the Flaw.  Some flaws can be overcome in time, with role played work towards that end.  Others might be overcome by a high-level Cleric, but the cost might involve a side quest or a great amount of money.
