I just can't win with how I phrase the grell's bite attack, can I? At least you understood what it meant.

Blindsight: A first-level psicrystal gets something approaching this to 40'. It felt somewhat crippling to reduce it much further, since it's already quite weak to ranged attacks, not having sight. Giving a bit of blindsense could help make up for that, though. Also, probably a good idea to have blindsight that extends as far as you can reach. For a first-level grell with a whip, they can make semi-ranged attacks to within 20', so it would be odd if they couldn't 'see' that far.
