Went solo'ing around Blackthorns castle for the first time(finally catching up on game content),and so far it's pretty good. Because it has been a long time when I last fought liches,I had forgotten how fast they can cast flamestrikes. But that's another story. My question is what's the deal with Kiatha the Archer in Blackthorns Castle? An invulnerable(yellow named) npc that can attack? What's the deal with that?
