Luck

Luck

Luck increases the chances of finding Item Boxes, consumables dropped by enemies. It increases the rartiy of items found in loot crates, the items found in the shop, and the Upgrades offered when leveling up. Positive Luck multiplies your chances, so 100% luck doubles your chances. While negative luck divides your chances. So -100% luck halves your chances. While luck in itself has no limit, several of its benefit have maximums or diminishing returns.

For example, the rarity of items and upgrades offered, already naturally increases with the wave number, and has a maximum chance, that you already hit in the later waves naturally even with 0 luck. So additional luck only helps earlier in the game with getting Tier 2 and 3 items and upgrades. However it takes about 290 Luck before you reach the maximum on Legendary items and Upgrades.

Check Shop to see Luck's effect on shop rarities.

Item box spawn chance is multiplied by Luck. But note that each Item Box dropped reduces the chance of the next dropping, giving you some diminishing returns.

Formula for item box spawn chance:

Enemy_Box_Drop_Chance * (100% + Luck) / (1 + Box_Spawned_This_Wave)

Luck can be seen as an investment into your economy, and even become a powerful method of healing when combined with Lemonade and Weird Food, if you have high enough luck. There isn't diminishing returns on the chance for Consumables to drop.
