Item: Skull Pauldrons mounted with a pair of slain monster skulls, giving the wearer two extra Head Slots on which to wear hats, helmets, periapts, &c., gaining any magical effects of those items. Both skulls can talk and have their senses (sight, hearing, &c.) but cannot move; the one on the left is Lawful Evil, the right Chaotic Evil.

  • offering strategy advice
  • mumbling at inopportune moments about their hat being out of style
  • complaining about wanting to trade places with the “main head”
  • if the party is good-aligned, actively trying to get them killed by yelling to attract monsters
  • technically you could also make use of their Eye slots, but do you really want a couple of Evil-aligned liches mounted to your shoulders to have Heat-Ray Vision or whatever
  • wily characters might manage to use some alignment-altering magic on them
  • general silliness that comes from forcing a character to wear a couple of NPCs around

Item: Cossack Dad-Guitar (contrabass balalaika) and matching pompadour wig. Playing a funky bassline while making eye contact with a character (that can hear the music) acts as Charm Person, lasting as long as the eye contact is held. Any actions they take while charmed will be made in time with the rhythm. The wig must be in place the entire time; if the wig is removed from the player’s head, the spell ends.
