@Lockepick<br/><br/>Change my Metaphor to True Seeing not making you immune to Weird. If you could tell it wasn't real you would automatically disbelieve it. It also doesn't mean you automatically take the lesser effects of shadow evocations. Simulacrum is a shadow spell at that.<br/><br/>A crystal ball with true seeing is one of the options, yes.<br/><br/>A simulacrum is affected by things like it was the biological entity it copied. If we were to say it acts as a "Major Image" than you'd have no hope of defeating it because it's immune to damage, it's also immune to level drain by way of being ice and snow making the absorption irrelevant. You wouldn't compare it to major image you'd compare it to "Shades" you have to save vs shades to disbelieve true seeing doesn't automatically reduce it. Shades summons also have the same vulnerabilities and requirements of the creature they duplicate. A shades Erinyes is alive and needs to breathe.<br/><br/>If you want to nitpick words like "Illusory Duplicate". Which we could say doesn't mean true seeing counters it since true seeing does not automatically confer immunity to all illusion effects.  It does say "It appears to be the same as the original" not anything that implies it's a construct of ice covered by a "disguise self" like illusion.<br/>
