Rake is a theoretical variation of Punch suggested by MA72's Eye-Rake.
It can be FULLY bought off, unlike Eye-Poke or Lethal Eye-Poke which can only be bought up to half per usual Targeted Attack rules.
This suggests that like Eye-Gouge the baseline technique is actually considered to be GRAPPLING the eye, since grappling is the only TA which can be fully bought off.
This is also seen in Ear Clap which is a targeted attack which can be fully bought off.
Raking the eyes can generate a HT roll for blindness like how a Clap can generate a HT roll for deafness.
This is in lieu of damage, unlike Gouge which does ONLY damage and Clap which does both.
