Scales best when found early on chest-heavy routes—open more chests, get more Luck, see higher-tier rewards later.
Each Green Credit Card now increases chest prices by +10%. Stacking multiple cards can make chests very expensive. Balance Luck gains against gold cost.
“Green” refers to the card’s color, not item rarity. The item’s rarity is Rare (blue).
Credit Card (Green) is a Rare passive Item. Every chest you open adds +2% Luck for the rest of that run. This applies to regular, free, and golden chests.
The +2% Luck stacks additively with other Luck sources (e.g., Clover, tomes), enhancing your overall chance to see Rare/Epic/Legendary rewards.
It’s a classic scale-now, snowball-later item. Early pickups can dramatically improve your item quality by mid-/late-game.
Available by default.
Increasing overall Luck (e.g., Clover, Luck-focused tomes) improves the chance that higher-tier rewards are offered later in the run.
Two levers make Green Card shine: more Luck and more chests.
Flat Luck boost that multiplies the value of each +2% stack from opened chests.
Persistent Luck increases during the run raise the average rarity of your offers, compounding Green Card’s payoff.
Grants a chance to open chests for free—more chests opened overall means more +2% stacks for the same gold budget.
Near the final stage, there’s no time for it to stack—combat stats usually outperform.
If you skip optional chests, Green Card won’t scale.
