Editing Mano a Mano:Success Rolls (section)

===Rolls and Modifiers=== 

[[Image:MamDice.png|right]]Some actions are always successful and some are never successful, but many actions have a random chance of success. When rolling for the success of an action, roll a twenty-sided die (d20) and add success modifiers to the result. If the total is greater than the difficulty of the action plus difficulty modifiers, then the action is successful. The action is also ''automatically'' successful if the die roll is 20 before adding success modifiers.

If you do not have a d20, you can roll a ten-sided die (d10) and double the result (d10 &times; 2). If you roll a 1 the doubled result is 2, if you roll a 2 the doubled result is 4, if you roll a 3 the doubled result is 6, and so on. Most d10 are numbered 0 to 9, but the 0 represents 1, so if you roll a 0, the doubled result is 20. The chance of getting 20 this way is twice as likely, so you can ignore the automatic success rule, or make a second d10 roll, but don't double the result. If the second roll is more than 5 then the action is automatically successful.

If you do not have a d10 or a d20 you can use a six-sided, eight-sided or twelve-sided die (d6, d8 or d12). Subtract 1 from the result and then double the value if you use a d12, triple the value if you use a d8, and multiply the result by 4 if you use a d6. (Instead of subtracting 1 it may be simpler to count the highest number on the die as 0.) If the result is 20 or more, you can either ignore the automatic success rule, or make a second roll with the same die. If the second roll is more than 8 on a d12, more than 5 on a d8, or more than 4 on a d6 the action is automatically successful.
