(2 Point Flaw)
You can't see out of one eye - because it's not there. You have no peripheral vision on your blind side, and you roll two (2) fewer dice when a situation involves depth perception (including ranged combat).
Metis characters may take this Flaw as their metis disfigurement. Additionally, a metis character who takes this Flaw as his deformity may have a cyclopean appearance, with the one eye centered on his forehead. This feature can well affect his social life by increasing the difficulties of all Social rolls by 2. Such a metis may well have no peripheral vision whatsoever.
