N18 Visibility and charging around corners

[Tchuck]

Our group started the Underhells campaign and this question came up.
Does the visibility (x") rule stop fighters from charging another fighter around a corner (no LoS) that is withing x"?

Visibility rule
".. In addition, models may not make a Charge (Double) action against enemies who they cannot see (for example, their target must be within X" or have a Blaze or Revealed marker on them or be wearing a refractor field)."

My read on this is they would have to be within x"--measuring around the corner and what not--to be eligible to make the charge (assuming the model isn't revealed). They would get the -1 to hit for "blind charging" if they cannot "see" their target before the charge.

It seems fairly clear that the RAIntended here is that "cannot see" is referring to Hidden, since it is specifically under the header of "Visibility (X)," and since all of their examples specifically refer to things that cause a Hidden model to be Revealed. If the same text appeared instead under the header "Line of Sight," then I would think it applied to LoS instead. But this is pretty clearly intended to be an explanation of the Visibility (X) / Hidden / Revealed rules.

If the fighter is within X", or is Revealed, they should be able to be shot at or charged under the usual rules for shooting and charging.

The section being cited in that quote isn't about Line of Sight at all, but exclusively about the Hidden / Revealed condition and it headed as "PITCH BLACK & VISIBILITY". These are the same conditions it uses earlier in the same paragraph when talking about ranged attacks. Line of Sight is not even entered into the discussion in the Ranged Attacks section. And the earlier sentences in the same paragraph make it very clear that what is being discussed is the Hidden / Revealed condition, and not Line of Sight at all.

All models are subject to the Hidden condition unless they are using a photo-lumen, are subject to the Blaze condition, or become Revealed (as follows).
• Ranged attacks may not be made against targets more than X" away unless the target has replaced the Hidden condition with the Blaze condition or Revealed condition (as follows), or is using a photo-lumen. Fighters using photo-lumens, photo-goggles or infra-sights extend this range by 9" (note these and similar effects do not stack). In addition, models may not make a Charge (Double) action against enemies who they cannot see (for example, their target must be within X" or have a Blaze or Revealed marker on them or be wearing a refractor field).
• If any model subject to the Hidden condition makes a ranged attack (with the exception of weapons that have the Silent weapon trait), makes a close combat attack using a weapon with the Power trait, or is a vehicle that moves, remove the Hidden condition from them and replace it with the Revealed condition. In the End phase of each round, Revealed models become Hidden again unless they are also subject to the Blaze condition.

So again, this whole section isn't considering Line of Sight at all. It is very explicitly, exclusively, deliberately, about Hidden / Revealed, instead.

Edit: and so yes, they could charge someone within X" and outside LoS, or Revealed and outside LoS, in which case they would get a -1 to hit modifier. And no, they could NOT charge someone beyond X" and not Revealed but within LoS.
