Reroll the dice if it matches the condition, but do not roll again if the reroll also matches. Only keep rolls matching the condition Drop rolls matching the condition Keep the highest n rolls, if number is omitted it defaults to 1 Keep the lowest n rolls, if number is omitted it defaults to 1 Drop highest rolls, if number is omitted it defaults to 1 Drop lowest rolls, if number is omitted it defaults to 1 Exploding dice, reroll any dice that match the condition and subsequent rolls that match, if condition is omitted defaults to highest value of the dice.
