Dancer thralls are used by a lot of people for decoration. How about having an item called “Dancing Platform” that is a small wooden circle a foot high, about a foundation in diameter, where the dancer could be placed to dance?
The dancing platform would have a one slot inventory where a dancer (or maybe also a bearer) could be placed. The dancer would dance only, and provide healing buffs, but would not be able to fight… He/she would just keep dancing, like the crafting thrall keep crafting, and would not be interact-able.
Perhaps the dancing platform itself could be use to assign the type of dance the owner wanted the entertainer to perform. Also, the dancer on the platform would not count towards player/clan follower caps.
