Gilded Key

Effects

Replaces all new chests with (Locked Chest) Golden Chests.
Modifies the contents of Golden Chests to be able to give cards and trinkets from a single chest alongside normal pickups.
- Also allows Golden Chests to drop pills.
Gives Isaac one (Key) Key when picked up for the first time.

(Old Chest) Old Chests and (Mega Chest) Mega Chests cannot be overwritten by Golden Chests.
The contents of Golden Chests can be changed retroactively by picking up/dropping Gilded Key. This can even be observed if Isaac has (Guppy's Eye) Guppy's Eye, allowing him to see what the chest would have if he did(n't) have the key and choose which payout he wants.
- This also applies to chests that use Golden Chests' loot systems, such as (Bomb Chest) Bomb Chests and (Eternal Chest) Eternal Chests.
- Mega Chests will also have their contents modified if they didn't contain items.
- The difference in contents between the two chest payouts are independent from each other; regardless of if the original chest had an item, card, trinket, or pickups, the modified chest can have any combination of them.
  - Modified chests are still unable to spawn pickups alongside items.
Gilded Key does not retroactively change chests that have already spawned into Golden Chests, or change their contents.
Golden Chests in will still spawn items.
The unique (Red Chest) Red Chests in the beginning room of the (Dark Room) Dark Room will be replaced.
