Saving Throw Will negates (harmless); Spell Resistance yes (harmless)
You confer upon the target the ability to see all things within 120 feet as they actually are. The target sees through normal and magical darkness, notices secret doors hidden by magic, sees the exact locations of creatures or objects that are invisible or displaced, sees through illusions, and sees the true form of changed or transmuted things. Further, the target can focus its vision to see into the Ethereal Plane (but not into extradimensional spaces).
True seeing, however, does not penetrate solid objects. It in no way confers X-ray vision or its equivalent. It does not negate concealment, including that caused by fog and the like. True seeing does not help the viewer see through mundane disguises, spot creatures who are simply hiding, or notice secret doors hidden by mundane means.
