Love potion (has the flaw of making the user loved by anything with even a hint of life). Gender-swapping device (20% chance of a perfect swap, 80% chance of a partial one). Teleportation device (can summon someone if they consent, but causes extreme motion sickness), etc. Relationship with Guest: Childhood friend.
