Luck

Luck

You have an x% more chance of finding items or consumables when you kill enemies. Also increases the rarity of the items in the shop and level upgrades. There is no limit to luck but there may be a soft cap. If it is negative you lose x materials and XP at the end of a wave. Does not further scale downwards.

Luck for rolling shop items

	Min Wave	Base Chance	+Chance per Wave	Max Chance
Tier 1	1	100%	0%	100%
Tier 2	1	0%	6%	60%
Tier 3	3	0%	2%	25%
Tier 4	7	0%	0.23%	8%

Calculation for chances are done by:

= ((Chance per Wave * (Current Wave - Min Wave)) + Base Chance) * (100%+Luck) 

Chance per wave starts adding chance after the Min Wave.

This value cannot exceed Max Chance.

Luck increases these chances by x%, but that still cannot exceed Max Chance.

For example:

• In wave 10, chance for Tier 3 is 2*7 = 14%
• If the player has 100 Luck it increases by 100%, 14*2 = 28%
• However, Max Chance for Tier 3 is 25%
• Therefore, Chance for Tier 3 ends up as 25%
