I agree with the general thread consensus here that Darkvision and other sensory enhancements described as "vision", either in their names or descriptions (so, Infravision, Ultravision, Night Vision, etc.) are, by default, linked to your eyes, and count as sight for purposes of sense-based attacks that use sight as a channel. I would allow a "Separate Sense Organ" enhancement on most such abilities. That would mean the sense depends on a separate eye or other, similar organ. It would have the same basic limitations as an eye - it faces the same direction as your "normal" vision, it's easily crippled by damage, and it's subject to blinding by environmental hazards. This would be worth +5% if it's just another eye, an additional +5% if the sense organ isn't obviously an eye (and thus needs something like a Physiology roll to identify its function), and a final +5% if the sense counts as something else besides vision for purposes of Sense-Based attacks.
