The judging process for the Onegeon Jam is simple and impartial. If your Onegeon weighs more than the feather of Ma’at it gets eaten by Ammit.
She’s hungry.
Give me more heavy Onegeons before she gets upset.

Rather than assigning “Rock, Paper, or Scissors” at each landmark and having to do the calculations every time a player chooses a direction—I went ahead and did that for you!

What I like about this one is that even though it could be extremely deadly, it also has a lot of clues for players to work with to figure out that something is off and try to work it out.

Some Ongeons are full of danger, others have a bunch of weird and interesting things to grab or play with, and also danger.
I love this alchemist’s lab packed with magic items.
The potion that smells and tastes like cabbage soup is excellent.

Reminder you have my permission to mute the #OnegeonJam tag. It’s gonna be several months of me posting regularly about this thing, but I’m gonna make an effort to tag every one so folks can filter it out.
The feed can get annoying fast with too many posts about the same thing.
