When I played with Valen, I discovered alot of lowlevel priests (I have seen this mentioned) who used sunray and false dawn as soon as they see her. The problem, as I see it, is that the priest that attacks you in Garrens Cabin can hit Valen with a sunray even if she leaves the house.
No problem, of course, I reloaded, and killed her quickly, but her targeting gives me a bad taste, cause I wonder if Amelyssan will do the same? If she can target Valen, then Valen is doomed, cause there is no way you can kill Amelyssan before she pulls off a sunray.
Also, is it possible to keep Valen hidden from most of the neutral clerics in TOB?
