On page 192 of the BC Core Rules indicates a Bionic/Implant called Tox nails. I see no description of said item in the book. Does anyone know where it is or is this something that needs to be added in an update? Do we have an errata thread started?

It is listed earlier in the equipment chapter, bundled in with the Venom Ring.

Which page is the venom ring thing?

The barbed ring/venom nail actually has a much harder availability than the tox nail. I don't think this was ever addressed in the forums or the errata, but I think the ability the venom nail gives is probably a bit too awesome for an availability of scarce such as the tox nail has.

For anyone who still plays the game, perhaps giving unarmed attacks the toxic(0) trait might be a good compromise.
