You create a faint illusory line between yourself and one creature within
range, which requires a successful ranged touch attack. This line causes
no damage and does not illuminate an area. The spell ends if you no longer
have line of effect between yourself and the target.
Any ranged touch attacks you make against the target gain
a +2 circumstance bonus to hit, and concealment for these attacks is treated
as one category less. If the target is an invisble creature, the line pinpoints
the square for you (negating the need to choose a square to attack). Because
the line is a visible illusion, it has no effect in darkness unless you
can otherwise see in darkness (such as with darkvision) or if you cannot
see the line because you are blind.
Because the spell also indicates a direct line to you,
the target gains the same benefits against you that you do against it.
The target may attempt to disbelieve the illusion as normal, but successful
disbelief has no effect on the spell's benefits (the translucent outline
of the revealed illusion works just as well as the illusion itself).
