Thickening Stench

Focus {2}

If you rolled any blocking {x}'s, and did not receive
any damage in this column, you may discard this.
If you do, all players must discard all of their board
cards.

For each card, players may remove dice from their
pool equal to the Focus cost of the card to keep it on
their board (cards with no Focus cost are considered
to be Focus {1}).
