Botch
A Botch is when you have failed very very badly at a Trait or Skill roll.
If you roll 1 on a die and that die is not Exploding, re-roll to check for a Botch.
If a 1 is rolled again, you Botch.
If any other number is rolled, your d6 roll is counted as a normal 1.
The Narrator has a great deal of latitude to be creative when determining the effects of Botching under various circumstances, but they should always be fair.
Whenever a Character Botches, they get +1 XP because we learn the most from our greatest failures.
