Blindfighting

The art of being able to fight - even when one can't see their foes.

Ability Score(s): Precision + Reaction + Intuition

Usage: Blindfighting involves being able to determine and where an individual is and attempting to attack them, despite being unable to see them either due to your own eyesight or due to the opponent being invisible. If you're suffering from the Blindness status effect or the opponent is benefitting from Concealment, you can use this skill in order to try and mitigate the penalties. This skill cannot be used with ranged attacks, only melee attack rolls.

Low Intensity Blindness requires a DC 28 to made, Moderate Intensity requires a DC 35 check, and finally Severe Intensity requires a DC 50 check to be made. If your roll beats the DC, you don't suffer the penalties to attack, Physical Defense, and movement.

If your opponent has concealment against you instead, the DC is dependent on how much concealment they have; regular concealment is a DC 40 whereas Total Concealment is a DC 70. If you beat the DC, you don't suffer the penalties to attack.

Finally, if you make an attack roll while suffering the effects of blindness (and haven't used Blindfighting to reduce the penalties or failed on your roll) you can add Blindfighting as an Exchange instead.
