Thanks to my nephew with the 3D Printer and the willingness to give us time for Heroscape projects we finally have the Toxic Liquid tile that goes with the Alien Flora.
Toxic Liquid Rules:
Moving onto toxic liquid: Unlike moving onto water, when you move onto a toxic liquid space from any other space, you may continue moving if you have move left. However, at the end of the round, all figures still on toxic liquid spaces must roll to see if they take toxic liquid damage.
Rolling for toxic liquid damage: In turn order, all players must roll for all their figures on toxic liquid 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.
Falling: All falling rules apply if a figure falls onto a toxic water space.
Misty Swamp (optional rule): When a small or medium figure on a toxic liquid space is defending against a non-adjacent attack, the defending figure receives one additional defense die.
