How To Summon The Guardian Knight Chess Piece

Once players have a knight chess piece, they will need tohead on over to the Sitting Roomswhere Stamin-Up is located. Within this room, players willfind a chessboardsitting atop a wooden table.

Interacting with the chessboardwill begin the summoning process, with an area of effect surrounding the table. To summon the Guardian Knight chess piece, players simply need tocharge the board with zombie soulsby killing as many zombies as they can within the area of effect.

Be sure to begin the summoning process during a round where there are plenty of zombies available, as the ritual may end if players have not supplied the board with a sufficient number of zombie souls.

Once the board has been charged with sufficient zombie souls, the Guardian Knight chess piece will be summoned. This chess piece willbegin to follow the player who summoned it, releasing a PHD Flopper blast each time it moves. If any zombie is unfortunate enough to be in its path, it may very well be squashed or knocked back. While the Guardian Knight does follow the player for a while, it will not stay forever, as it will eventually disappear.
