a question about "every turn"

we can say

every turn:
so and so happens.

is there a way to make it every 2 turns or 3 or 5? and if so how is that worded?

Here’s one way:

[Every 3d turn beginning with the 1st]
Every turn: if the remainder after dividing turn count by 3 is 1, say "first".
[Every 3d turn beginning with the 2d]
Every turn: if the remainder after dividing turn count by 3 is 2, say "second".
[Every 3d turn beginning with the last]
Every turn: if the remainder after dividing turn count by 3 is 0, say "third".

(‘Turn count’ is a global variable defined by the Standard Rules and is incremented each turn.)

For every two turns, you can also use this.

[code]Every turn when the turn count is even: say “The turn count is even.”.

Every turn when the turn count is odd: say “The turn count is odd.”.[/code]

If you use this method quite a lot, you can also define adjectives similar to even and odd for divisibilties greater than two, like so.

[code]Definition: a number is triplicate if the remainder after dividing it by 3 is 0.

Definition: a number is triplicate one if the remainder after dividing it by 3 is 1.

Definition: a number is triplicate two if the remainder after dividing it by 3 is 2.

Every turn when the turn count is triplicate: say “The turn count is triplicate.”.

Every turn when the turn count is triplicate one: say “The turn count is triplicate one.”.

Every turn when the turn count is triplicate two: say “The turn count is triplicate two.”.[/code]

Hope this helps.
