Editing Cycle 16/Ruleset (section)

== Randomness ==
When randomisation is concerned in this ruleset, it must be resolved by a generally trusted and fair method accessible to all players in the game, and as soon as possible.

When a rule would have a player determine something by random chance, that player should resolve the random chance as their next act, and must resolve it before other actions involving the result of the triggering event may take place - or by phase end. If the randomisation is not resolved, then the event either does not take place, or takes place with only the non-random, non-optional elements resolved.

For instance, if a player receives an item with an optional random chance of having a special trait, they must randomly determine that trait before they may perform actions involving that item, or else the gaining of that trait fails by default. If a player would receive an item with a random attribute that must be determined, they do not receive that item until the attribute is determined.

=== Random Choices ===
A person shall not deliberately select random values for a rules-defined action without intending to use those values to the best of their ability to resolve that action.

If a person has selected some or all of the random values necessary to perform an action, they shall not discard the valid specifications in order to attempt a substantially similar action with the goal of obtaining different random values. If there is consensus that a preponderance of the evidence exists, or if a Judge ruling, not overturned, finds that a player has done such a thing, all attempts other than the first are deemed to be invalid and to not have affected the gamestate.

=== Dice Rolls ===
A rule that requires a selection of an NdK value, for non-negative integer N and positive integer K, is requiring the random selection of N rolls of a K-sided die.

* If not otherwise specified, this produces the sum of N rolls of a K-sided die; that is, the sum of N independent selections of integers from 1 to K, using a uniform random distribution. If N is zero, the sum is zero.

* If a rule requires an NdK dice roll with a target number x, this instead produces the number of N independent 1dK rolls that meet or exceed the target number and can be abbreviated as "x+". For example, if a rule requires a dice roll with a target number of 3, this can be abbreviated to "3+".

=== Luck ===
If a player has good luck, once per phase, when selecting a random choice, they may reroll, by declaring the original outcome of the chance to have not happened, and any effects thereof to be null. They must then select a new random value for that choice, with any effects

Rules to the contrary notwithstanding, a player with good luck may only reroll their luck once in a game of exoptosis.
