This game uses rolling dice as the method of determining what happens in a world full of uncertainty with too many factors to consider.
By default a roll is made by rolling a d20 and adding a modifier.

Roll types

Rolls are generally one of these 5 types:

Crafting, Combat, Exploration, Social, and Luck.

Roll Parts

A roll consists of two parts that are added together, the Dice Value and the Flat Value.

The Dice Value is the sum of all numbers rolled on the dice. (Also handling any taking highest / lowest, explosions, etc.)

The Flat Value is the static number added to the Dice Value.

Nat

The Natural Value of a d20 roll is the Dice Value of just the d20 (ignoring any other dice that may be rolled alongside).

On a Nat 20 on a Hit roll, a Strike is a Critical Strike.
