Permanent Blindness

You are permanently blind, perhaps you were born blind or maybe you lost your sight later in life.

Being permanently blind imposes the following penalties upon you:

• You can't see and automatically fail any ability check that requires sight.
• You have disadvantage on attack rolls against targets further than 10ft away.
• Attack rolls against you have advantage, at the DM's discretion, if the attack does not make much sound.
• You can't cast spells that require you to see a target.
• Without some kind of walking cane or other assistance, you constantly bump into stationary and silent objects
• You are unaffected by any positive effects or spells that would normally be imposed upon you through sight.
• You are unable to travel at a fast pace.
• Enemies can attempt to hide from you, in what would normally be in plain sight of you.

Being permanently blind imposes the following benefits upon you:

• You are unaffected by any negative effects or spells that would normally be imposed upon you through sight.
• You have advantage on Wisdom (Perception) checks that rely on sound or smell.
• You have blindsight and tremorsense up to 30ft + your character level times two.

Furthermore, the following applies:

• You can lose your blindsight at the DM's discretion, if there is too much random noise in the environment.
• You can lose your tremorsense at the DM's discretion, if there are too many random ground vibrations.
• If at any point spells or other means grant you temporary vision (eg. a familiar providing sight), then you keep your advantage on Wisdom (Perception) checks that rely on sound or smell, but all other effects of this feat are nullified.
