I am going to be running a scenario soon where some PCs are going to be protecting an NPC while a spirit is trying to teach the NPC to play the banjo. If monsters spend 2 rounds adjacent to the NPC, the scenario is failed.
At point b of this, 3 leprechauns emerge from the surrounding woods and try to distract the NPC and the PCs with pranks and illusions unless the PCs kill them or offer them alcohol.
My question is, what are some things I can do with these leprechauns (found in Bestiary 2) to make this fun(ny), memorable and challenging?
I am currently trying to make a side quest with the Leprechaun Mafia. It seems cool to have a whole fey crime family. I also like the idea of a horrible std going around called Leprechaunaria.......
