<strong>Lockepick:</strong>I say mind blank may be most relevant defense/counter vs true seeing and divinations, however Vholdran ignores mind blank (I remember it was ruled he can 'detect and see' through his glowing green eyes which allow stick his limbs through to cast spells through them). So I had to self-rule would Vholdran able tell simulacrum is fake or not?<br/><br/>Simple answer; he does not know what Grimjaw really likes so disguise is moot anyway (so is for Methu). Vholdran just know basic appearance of astral stalkers and that this one has big jaw and the name. Simulacrum fills the description of that.<br/><br/>Now, simulacrum is illusion duplicate but it's also a shadow effect and shadow effects mimic something unreal to be real as possible. The simulacrum has half of power and HP of original but IC Vholdran does not know exact power level and HP of real Grimjaw and either one cannot be told by true seeing spell anyways (nor Lifesense tell HP for that matter; it just detect's life force and amount of HD target has and simulacra Grimjaw was quite mighty for a 'illusion clone').<br/><br/>Then it boils to that it takes lots gp to craft simulacra and base component usually is snow/ice/dirt mixed in. But simulacra's physical structure is identical to original. It's basically like baking a sandman from sand and then use magic to turn it into a real living and breathing man. True seeing main function is meant see through disguises and glamer/illusions which conceal truth (thus word 'true' in seeing). It allows see transmuted things as they really are.<br/><br/>However there is wording that it does not allow see through mundane disguises and you need disguise roll with simulacra (in regards making it real as possible looking to original and most people familiar with original easily recognizes the fake one with DC 20 sense motive check albeit by my own ruling simulacra can roll bluff check to hide the fact if it wants to).<br/><br/>I have tried search internet official answer and so far it boils down to this; GM decides. So by my decision, as GM, true seeing does not allow recognize simulacra as fake or simulacra as simulacra. You need roll spot check see through disguise (if know what original looks like), sense motive if very familiar with subject (can possibly countered by bluff check done by simulacra). As physical form of simulacra is basically identical in texture/feeling as original (albeit not exact identical, so thus needing disguise check to make simulacra look like original). This applies to all simulacra despite what material they are made from (snow, ash, dirt or mirror mephit creating mirrored clone which shatters like glass when it dies).<br/><br/>Simulacra may not age nor progress in levels but it has same biological needs like original has (sleeping, eating, breathing etc) and simulacra can hurt and interacted as living being (if simulacra cloned living being) or affected like undead (if it was made clone from a lich or undead caster). So energy drain and such works on simulacra as it's not just a 'construct' but by shadow essence mimicking living entity (so thus interacts all purpose wise, including making women pregnant and birth life like regular would).<br/><br/>Only off hand divination which would reveal simulacra is simply divination which targets (specifically) simulacra (example simulacra who appears king sitting on throne and ruling a kingdom) and ask; "Is king sitting on the throne same king as one who founded kingdom?" (original king died but simulacra remained) and divination (when going right) would reply; "No, king on throne is not same as one who founded kingdom."<br/><br/>Or more directly ask 'Is person before me real/original?' and answer with commune would be 'No'. As in end simulacra, even if living entity, is fake one and thus for divinations confirm is he real or not always gives negative albeit no divination who pierces visual illusions can reveal the false nature as simulacra is disguised mundane method to look like original (than magically). If simulacra disguise is improved with disguise self (speaking or horrible botch on disguise roll by wizard who rarely invested ranks on disguise skill), then true seeing sees through disguise self but not reveal simulacra as simulacra (this case simulacra appears as guy who has used illusion look like someone else).<br/><br/>I hope above finally settles the issue. The mention of Grimjaw's ability or other elements is just that there is multiple layers of defenses in place prevent being 'seen through' but most critical part is this;<em>simulacra fooled you because as I GM decided that true seeing does not trump over it</em>. Same way I decided energy drain from Methu (who ignores any immunity besides being undead) can be adsorbed/reduced in impact with specific magic items (and effects/spells) which adsorb negative levels as I felt as GM it made sense (it does not prevent Methu doing dmg, but rather soaks it up like temporal HP soaks dmg).<br/><br/>Idea was not meant screw Methu's build or concept over but just means make foes bit more resilient if possible at times (not always, but sometimes) against Methu. Methu's build I approved and I am okay with it, just wanted add sense that his attack can be resisted other ways than just throwing undead at him or have restoration spamming clerics around.
