Can only be taken at level 1
You are deathly afraid of being enclosed. If you are underground or in an enclosed area, you suffer disadvantage on all attack rolls, ability checks and saving throws. 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 feat, or increase two of ability scores by +1 (or one by +2).
