Arcanum Hypnosis

Arcanum Hypnosis is a Relic Created by the Great Kings.

A pair of bracelets.

You can make a command to Arcanum Hypnosis. It will then forcibly take over your body and make YOU complete that command. It will not relinquish control until the condition it met.

Anything that is physically possible for the User can be issued as a command, regardless of how they'll end up after.

If it's literally not possible, Arcanum Hypnosis won't do anything.

You best be dedicated to whatever commands you issue to Arcanum Hypnosis. If you're not careful you could end up dead. It doesn't care whether you do or not.
