57 Leaf Clover

The 57 Leaf Clover is a new 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 the number of clovers the player has.

For example, a player has one Sentient Meat Hook, the chance to proc it on hit is 20%, and has one 57 Leaf Clover. If the player attacks, and the meat hook 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 tlriggered 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 effect them.

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: Item Stacking)

x = the number of clovers in the player’s inventory

y = new item proc chance (0-1) with x amount of clovers
