Coming back to this, although maybe should be moved to the
AotP project. An idea to combine a few different ideas:
Quicksand movement:
Figures starting their move on quicksand spaces subtract 3 from their move, to a minimum of 2. Figures on quick-sand spaces cannot target non-adjacent figures for attacks.
Quicksand damage:
Rolling for quicksand damage: In turn order, all players must roll for all their figures not adjacent to friendly figures and are on quicksand spaces. To do this, roll one attack die. If you roll a skull, that figure takes a wound. Otherwise it is safe. Players may choose in what order to roll for their own figures.
Figures with Slither, Amphibious, Water Suits, Swamp Water Tunnel, Water Tunnel, or Super Strength special power can ignore quicksand movement rules and never roll for quicksand damage.
