So, just post in this format:
# of strips they will survive: (Your guess.)
In Character bet: (Something you'd be willing to give/do in character for the winner, the less worthwile the bet, the less your actual win will be. And you might just have to do what the bet is too. Depends on who wins, what their bet was, how close they were, and if they even want it.)
Of course, I don't know if I'll hold you to the In character bet thing, I just figured I'd have that instead of fake money. People tend to place millions or billions, even trillions of fake $ in bets they lose every day, and I'm against that. (Though thousands of fake $ is fine.)
But seriously...
# of strips:
At least do that, the other part of the bet is off the top of my head, and mainly for humor.
Also, Non-Related strips do not count tword the strip count.
My guess: 9 Strips
My bet: Will teach the winner's character (Only one), how to do spellcrafting IC. If the character cannot use magic for some reason, will instead invent something to help them, depending on character specifics.
And i'm willing to keep my bet.

(To clarify, I'm talking about the EGS Mayhem in my Character teaching, though it extends to wherever your characters are.)
