crap I made up on the fly and then mistakenly let you keep
Here’s a nice little list of the random objects that someone has in the party on their person, most of which have been completely made up while in game by myself.
Binding collars and earings: made to hold slaves these items are highly illegal and require a DC 25 will check to not be compelled by them. If the power word is spoken by the person who initially put the collar on the slave then another will check of 35 must be made to not follow the exact orders of the owner. Owning these collars in a crime punishable by death in some kingdoms.
