Alternate Rules
Dice
Sometimes dice are used to calculate how many steps they have to take. Scoring may also be related to how many stones they can get beyond the die roll.
Living Pieces
Sometimes the kids will cover themselves in the spores (usually to the dismay of the parents). In this version they use large stones to keep themselves from floating up. They will use the die to see how many steps they have to take without floating away. You only get a point if you match your die roll. A rope is tied to you to pull you back down for your next turn.
Adult Versions
Despite the inconvenience of the spores for most adults, they do play some games with it. Their game primarily happens on the ceiling itself. They put enough spores on their bodies to float to the ceiling. There are three large floating stones passed around between the three teams. A team can score a point every time they can leap
up and grab the other teams stone. The game is very fast moving and contains quite a bit of contact, although it's usually only a shove as that is all it takes to take someone off their feet.
The games conclude when one team gets a specific number of points, decided at the beginning. These games will also draw in a few fans to cheer for their family and friends. The winning team gets some bragging rights until the next match.
This sounds like quite a fun game and definitely one that kids would make up. What's the potency like for these spores? For example if you put a little on a rock it gently float while if your completely cover it the rock shoots straight up. Or is there a limit to how fast they float?
Didn't consider potency. They float relatively slowly, so there is very little fear of hurting themselves on the way up. It can be dangerous once the spores dissipate though and someone could get hurt falling. This happens toward the end of Hollows Season, which most people try to stay indoors until all the floating objects fall to the ground.
