Sometimes, the rules or the Sage might call for a luck roll to see what happens. A luck roll uses no attribute, so it’s just a roll of a d20. Since you never make a luck roll against a creature or object, the target is always 10.

(LUCK ENDS): If you are subject to an effect that has the (luck ends) notation, you make a luck roll at the end of the round. If you have multiple (luck ends) effects affecting you, you make a separate luck roll for each effect, in any order you choose. If you have a (luck ends both) or (luck ends all) effect, you make a single roll. On a success, the effect ends. On a failure, the effect persists until the end of the next round, at which point you repeat the luck roll to end the effect.

You can end a (luck ends) effect with a successful use of the Overcome action (see page 47). Any (luck ends) effect ends automatically when combat ends.
