Evolutionary is a roleplaying game that uses dice to resolve conflicts between creatures. The following dice are used within the game; d4, d6, d8, d10, d12 and d20’.
As with many role playing games you have a game master who creates the world and adventure for the players. The game master will describe the world and scenes to the players and they will act according to their characters.
Dice are described as expressions and look like 2d6 and mean roll two six sided dice and add 4 to the result. Another example would be 2d10 and would require you to roll two ten sided dice. Also you might see 3d10L or 3d10H and these mean roll three ten sided dice and add the two lowest dice or roll three ten sided dice and add the two highest dice.
RULE OF ADDING
The most important rule when rolling dice in Evolutionary is that you never add more than two dice together thus any expression followed by an L or H refers to adding the two lowest or highest dice in the dice pool.
Rolling Attributes: Roll 6 times using 2d6+4 and then roll 2 times using 4d6H+4. This will give a result between 6 and 16 where two of the rolls will generally be higher and are placed depending on your creatures race.
Checks / Saves: Roll 2d10 and check the result against one of your attributes. This roll could also add a varied number of die 10's such as 4d10H where the results are always between 2 and 20. If the result is equal to or less than the attribute then the check or save is successful.
Attacks: Roll 2d10 and check the result against your opponents dodge score. This roll could also add a varied number of die 10's such as 4d10H where the results are always between 2 and 20. If the result is equal to or greater than the dodge score the attack hits the opponent.
Damage: Roll 1d20 and check the result against your opponents armor score. This roll could also add more 1d20's for damage but each one is checked individually and they are not added together. If the result is equal to or greater than the armor score a point of damage is recorded for the opponent. If multiple 1d20's hit then the opponent takes multiple points of damage.
Each player creates a creature for the game and plays out the actions for that creature. The actions may be stated or acted out as deemed appropriate. These creatures are fleshed out with attributes, races, backgrounds, professions, and classes. The personality, goals, and reactions are defined by the player as they would like to see their creature play out in the story of the game.
The game master creates, runs, and rules on how the world around the other players plays out within the story. They have a heavy burden of making sure the world plays out fair but difficult to the other players creatures. Too easy and the game is boring too hard and all the creatures will probably die. This balance if done well will create a fun and exciting experience for all of the players at the table.
