Sense-Based and Sense-Based (Reversed)

[Stripe]

Rules as written and canonically speaking, would it be required to combine both Vision-Based (p. B106) and Vision-Based (Reversed) (Powers, p. 105) if the trait requires that the attacker see the victim AND the victim see the attacker? Is this not necessary? Is this not allowed?

Vision-Based
[The] attack is channeled through [the] victim's [eyes], allowing it to ignore DR!

[The] attack only affects [a victim] who is using the targeted sense. For instance, a Vision-Based attack cannot affect a blind subject or someone with his eyes closed . . .

It's permissible to "reverse" Sense-Based to create an ability that works through the [attacker's] senses. To affect [the] target, [the attacker] must see it with unaided eyes (Vision-Based) . . .

For Vision-Based, the victim must see the attacker. For Vision-Based (Reversed), the attacker must see the victim.

I don't think those two things are mutually exclusive. For example, Reversed works against a blind victim, but the attacker can't be blind.

Rules quotes and page references appreciated.

Thanks!
