Sorry, forgot questions Lockepick.<br/><br/>1) No, because even if it's a illusion in school the simulacrum is more shadow stuff based construct which appears like the original (it's not magically identical/made look like original as there is disguise roll needed to make construct look similar to original). Vholdran would had instantly known it's a fake if simulacrum is countered by true seeing.<br/><br/>2) Indeed you can roll spot check vs disguise, but problem is you do not know what Grimjaw looks like (so pointless to roll as you haven't seen the original and thus not know simulacrum is construct disguised as him nor Vholdran had met Grimjaw either).<br/><br/>3) You can safely assume the original is no where near Soul Casket. Following astral stalker traditions the simulacrum may be just a 'warning' for prey Grimjaw is after him (very well suspecting simulacrum has no chance win fight vs Torahime in first place).<br/><br/>4) Even if amulet would not had prevented energy drain, you still would not had drained him to 0 HD. But I still stand on ground that absorption/redirection of the dmg works vs energy drain (or other forms of special attacks which ignore immunities, example there is feat/feature which could allow direct Anansil's own gaze back on her but it would be moot as I recall she is immune to death effects anyways). Considering the limit of absorption involved (at best delay death by 1-2 rounds in most cases).<br/><br/>5) Simulacrum do not raise as wights, but I would allow you take simulacrum's appearance if slain by energy drain as it holds spark of 'life' as it were.
