Amulet of the Golem

Amulet of the golem:

The bulk of this amulet, usually a strip of iron or a small chunk of stone, is made from the remains of a destroyed construct. Upon command, the wearer of this amulet becomes warded against constructs of all types, who cannot sense the wearer in any way, as per the hide from construct spell. The amulet does not offer protection against attacks from constructs ordered to attack into the wearer’s area, but because the construct cannot sense him, the wearer has total concealment against such attacks. This amulet can be activated up to five times per day, each use lasting 30 minutes.
