How to roll Mothership 1E dice
Roll d100 (1-100) against your skill value. Roll equal to or under to succeed. Doubles (11, 22, 33...) under your skill are critical successes; doubles over are critical failures. Advantage lets you roll two tens dice and take the lower; disadvantage takes the higher.
Key mechanics
- d100 percentile roll-under
- Critical success/failure (doubles)
- Panic checks (2d10 + stress)
- Advantage & disadvantage
- Stress tracking
