Home advantage: while standing in your own half of the board or one rank past it, each of your knights, bishops, and rooks may also step one square in any direction.
You draft Home Field in Buff mode. Passive: it works on its own the whole time you hold it, with nothing to activate.
As a movement card, it changes how one of your pieces is allowed to move.
“The crowd, the turf, the extra step.”
Affects your knights, bishops, and rooks.
