0 Rule Zero The Guide of
Modos is the player who ultimately decides what happens in
the story, with input from dice rolls and player
suggestions.
1 Campaign
Theme
The GM
creates a campaign theme for the game that describes what
the PCs can expect from the game.
2 Contest When a PC
wants to do something that has a questionable outcome, the
GM calls for a contest. The player rolls a d20 against the
GM’s d20. The higher result gets the better outcome.
3 Contest
Result
A contest
result is the sum of the d20 roll and applicable bonuses
or penalties. The higher result in a contest is called a
Pro, and gets a favorable outcome. The lower result is a
Con, and gets an unfavorable outcome. A Tie can be
rerolled or considered a neutral outcome. 002
4 Attack An attack is
a contest with an outcome that can be nullified by another
contest. 002
5 Defense A defense is
a contest made in response to an attack which negates the
attack with a Pro. 002, 003, 004
6 Awareness A character
has awareness when he is prepared to defend against an
attack. A character without awareness cannot defend
against attacks of which he is unaware. 002, 003, 004, 005
7 Bonus Die rolls
can be modified by static or random amounts called
bonuses. Negative bonuses are also called penalties. A
random amount is determined by another die roll.
8 Difficulty When story
conditions make a contest result more likely to be
favorable, it gains a bonus called Difficulty. Unfavorable
conditions impose a difficulty penalty. 002
9 Difficulty
Table
Some
difficulty bonuses are named to act as benchmarks. These
are: Easy (0), Challenging (4), Difficult (8), Arduous
(12), Impossible (16), Divine (20). 002, 008
10 Difficulty
Contest
A Difficulty
Contest is the GM’s opposing roll of a d20 + the
difficulty that represents the odds of an unfavorable
outcome. 002, 008
11 Minimum
Result
A contest
result below 1 is automatically a Con. 002, 003

may be replaced, before it is rolled, with a result of
half of the die’s highest number.
