Since neither the River nor the Konsort/Cult/Shrine is mentioned, I'm guessing this is
not a knock-off of
- Tower + Catapult + Count, King &
Cult Robber
but rather
- Tower + Catapult + Count of Carcassonne + King & Scout
(That would at least make sense as five separate line items.) If that's correct, then maybe "chaser" is the back-translation of whatever Mandarin word had been chosen as a translation for
scout?
