The 57 Leaf Clover is an item in Risk of Rain 2.

It affects all random effects other than Tougher Times. For each 57 leaf clover, if a successful proc is not achieved on a roll, it will be rolled one additional time, repeated again equal to the number of clovers the player has.

For example, a player has one item, the chance to proc it is 20%, and has one 57 Leaf Clover. If the player attacks, and the item does not proc, the roll will be done once more, as the player has one clover.

Successes are measured per effect, not in a whole, so if one item roll is successful, other items that were triggered by the same proc, will continue to roll If unsuccessful.

While the mechanic may be daunting, note that since items from chests are created on world seed, clover does not affect them.

In the game code, the number of clovers is referred to as "Luck" with each clover giving +1 luck. There are no other means of acquiring Luck. This means that Luck and number of Clovers are interchangeable. Due to the fact that negative Luck is also supported, other luck modifying mechanics may exist in the future.

In order to calculate proc probability with clovers, the following equation can be used:

y = 1 - (1 - p)^(x + 1)

Where:

  • p = total item proc chance (0-1), (See Also: Item Stacking)
  • x = the number of clovers in the player's inventory.
  • y = new item proc chance (0-1) with x amount of clovers

The inverse of the equation, that is to say the number of clovers required to achieve a certain proc probability, is:

x = log(1 - y) / log(1 - p) - 1

Plot of 57 Leaf Clover Proc Scaling

Proc chance of Runald's Band with base probability of 8%, and its new proc chance after 'x' stacks of Clover. Y-axis represents proc chance 'p' (0-1) as p * 100 (%). X- axis represents the number of Clover items, 'x'.
