One of the players in my game came up with a question we couldn't see an obvious answer for in the rulebook.
Using Cloak of Night he turned his character invisible, but asked what the effect of this was in terms of combat.
Assuming he succeeds well enough to be invisible for two rounds, what happens when he attacks an enemy?
The Choosing Targets out of Range box on page 253 mentions "a lack of visibility" and advises that the invisible character cannot be targeted except by the spending of opportunity subject to GM call, with no solid advice i could find about spends to see someone that is invisible.
The other option would be to look at the obscuring rules and either use, or maybe ramp up the most extreme option in obscured.
Is there something I've missed? Has anyone dealt with this question at their table?
