You might still have your hands full with the astral stalker. If he used some sort of non-illusionary mirror simulacrum like it sounds he baited you into ambushing him and is about to attack the pair of you. That or he's off hunting whoever his target is.<br/><br/>I have no idea if I'm overmatched yet or not. I think I can use enough magic to spot him. If he strips off my buffs or figures out how to keep me from glitterdusting him then I'll planeshift out and probably whine because my entire contribution to the fight will basically be less than that of cohort or minion since the only thing of substance I've done is activate a castle power anyone can activate. If he kills me I don't have any soul credit to respawn quickly yet so it's like 1d10 days to respawn so I likely just won't post until after the battle is over in that instance since I'll be busy being dead so I won't be able to interact with anyone. If I kill him/make him retreat (death spells or command undead beating his SR, will save, then his charisma check to make him do something that is probably against his nature to do by leaving with his army) then that leaves either the astral stalker or nobody still around depending on what is going on and the plot moves on to wherever it is going. If he captures me I'll probably try to suicide to respawn as quickly as possible otherwise I'm not sure what would happen in that case since it would depend on too many factors to guess at. I can't think of any other outcomes.<br/><br/>The main question would be if the demiplane shadow beats true-sight or not since if it doesn't the demiplane probably cloaks him from lifesense detection or otherwise he'll shift to undead and be able to hide from it as well.<br/><br/>I just need to at least be able to target him, which is the hardest part of the fight. I'm going to shadow evoke a spell for +10 to spot checks next and then wait for him to hit something with a readied action. Since I can interrupt/react to things I should be able to hit him with a glitterdust spell. I don't care about the blinding part but it gives a -40 to hide checks so it'll raise my spot up within 3 points his so when he is swinging I can ready an action to death gaze him then shift to either command undead or slay living depending on what he does. That's my plan at least.<br/><br/>He's an assassin though so I have no idea if he is studying me for three rounds or not. He did assassinate a wraith, which you can do with magic letting you do precise strikes, but I have no idea if his ability bypasses immunity in general or if he just has something to target undead. I have a high AC and 100% fortification from magic at the moment from the heart spells.<br/><br/>Since it takes a 3 rounds to study and he just swung my plan to check him is to cast my spot increasing spell then if he isn't killing wraiths on his turn I'll swarm the place with plague of undead to fill all the spots he could teleport to anywhere near me with creatures and try to force attacks of opportunity or just make him have to kill things to reach me so I can get the squares to glitterdust apparent.<br/><br/>That's basically my entire plan.
