Riverfolk Services
RiverfolkRoot
Other players buy services at the start of their own Birdsong by putting their own warriors in the Riverfolk Payments box equal to the service cost. The three services are Hand Card (take any card from the Riverfolk hand), Riverboats (treat rivers as paths this turn) and Mercenaries (use Riverfolk warriors as your own for rule and battle). A player may buy one service plus one for each clearing with a trade post and their faction pieces. The Vagabond pays by exhausting items.
