The 57 Leaf Clover is an item in Risk of Rain 2. It is the counter-item to Purity.pngPurityBgLunar.pngPurity.pngReduce your skill cooldowns by 2 seconds. You are unlucky.
All skill cooldowns are reduced by 2 (+1 per stack) seconds. All random effects are rolled +1 (+1 per stack) times for an unfavorable outcome.
.

It affects all random effects other than Tougher Times.pngTougher TimesBgCommon.pngTougher Times.pngChance to block incoming damage.
15% (+15% per stack) chance to block incoming damage. Unaffected by luck.
. 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.

Math[edit | edit source]

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)
  • 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

Interaction with Purity[edit | edit source]

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 positive Luck. This means that Luck and number of Clovers are interchangeable. Negative Luck is also supported, and can be obtained via the Lunar item Purity.pngPurityBgLunar.pngPurity.pngReduce your skill cooldowns by 2 seconds. You are unlucky.
All skill cooldowns are reduced by 2 (+1 per stack) seconds. All random effects are rolled +1 (+1 per stack) times for an unfavorable outcome.
. Positive and Negative Luck will cancel each other out, and thus an equal number of Clovers and Purity will equate to 0 Luck.

The game runs a proc chance Abs(Luck) times, where Luck is the total amount after Clovers (positive) & Purities (negative) are applied.

If the player has 7 Clovers and 5 Purity, the 5 Purity will cancel out 5 of the Clovers, resulting in 2 luck, the proc chance will be rolled two additional times for a positive outcome. If the amount of each item is switched, resulting in -2 luck, the proc chance will be rolled two additional times for a negative outcome; this can also be seen as the proc chance needing to roll successful three times for it to proc, (once for the initial roll and two more for each negative luck).

Exhaustive List of Clover Effects[edit | edit source]
