Adamantine wasp swarms are constructed by spellcasters and used to guard or patrol areas the creator wishes to keep “off limits.” From a distance, they resemble 1-foot long silver wasps, and some spellcasters further enhance this ruse by constructing fake nests nearby to detract would-be trespassers. Its body is segmented like a normal wasp (head, thorax, and abdomen) and has carefully and delicately been fitted together to form the wasp. A wicked-looking adamantine stinger protrudes from its abdomen. Its wings are formed of paper-thin adamantine, specially treated during the construction process.

An adamantine wasp swarm’s body requires 10,000 gp worth of adamantine, alloyed with ordinary steel and rare tinctures.
