Creating chase complication for vallaki.

TLDR: Party got split 2/2 with 2 chasing Escher who has the bones. Need some good/ fun chase complications and such for Vallaki especially any that are specific to the chaos during the feast of st andral.

So I'm using the expanded feast version with 18 vamps getting loose on the city. So in the coffin shop they all pop out but only 4 stick around to fight at first the rest for to cause havoc. Pcs got to the coffin shop snooped around and had 2 go in while the other 2 tried to climb the side of the building and look in through the windows. The paladin used devine sense and saw nothing initially since they where "behind total cover)

Once the 2 went in and triggered the vamps the 18 popped out and the paladin saw one holding a bag that was concencrated. He climbed in and hit 2 then Esher jumped out the windows and he followed, the barbarian failed his climbing check and fell to the ground so he was outside and joined the paladin so he wasn't alone. So both are outside and chased Esher off map. I delayed doing them and we finished the combat for the other 2 and ended the session there. (With the sorceress only having 15 max hp after the fight from being drained.)

As an extra note the barbarian has a silver long sword he found but the paladin doesn't have silver or magical sword. So he's basically screwed if 1 or more vamps turn to fight him.
