This pale gold, worn ring radiates magic.

The only difference betwixt this and the picture are a bunch of teeny-tiny centipede-like legs and a cute little pincer mouth.

This ring enables its wearer to exercise complete control over cilops. Up to 32 Hit Dice of cilops (8 adults) can be controlled. The wearer’s control over creatures is so great he can even command them to kill themselves, but complete concentration is required.

No command word needed, just focus upon the cilops in question.
