Luck

Luck

Luck improves the following things:

• It increases the amount of consumables dropped by enemies.
• It increases the chance that a consumables dropped is a Loot Crate (including those from Trees).
• It Improves the Tier of Items found in Loot Crates and in the Shop.
• It Improves the Tier of Upgrades being offered when leveling up.

Positive Luck multiplies your chances, so 100% luck doubles your chances. While negative luck divides your chances of finding higher tier upgrades, items, and weapons. So -100% luck halves your chances. For Consumables, negative luck multiplies your chances, so -50 Luck halves the amount of consumables dropped and -100 Luck means no consumables will drop at all, except from Loot Hoarders, Elites, and Bosses, which are guaranteed to drop Consumables.

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 Rarity of Shop Items to see details on Luck's effect on shop rarities.

Whenever an enemy drops a consumable, that consumable has a chance to be a Loot Crate. This chance is multiplied by Luck. Since 100 Luck both doubles the chances for a consumable to drop, and doubles the chance for that consumable to be a loot chest, 100 luck increases the chance for the first chest to drop by 300%.

But note that each Item Box dropped reduces the chance of the next dropping, giving you some diminishing returns.

Formula for loot crate drop 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.
