What is enter the gungeon altar?

The Altar is a special feature in Enter the Gungeon that allows players to sacrifice one of their weapons or items in exchange for a chance at getting a more powerful one. The Altar is located on the fifth floor of the game, and can only be accessed if the player has found the Old Crest item.

To interact with the Altar, the player must drop one of their weapons or items onto the Altar pedestal. Doing so will trigger a special event where the player must fight a group of enemies. If the player successfully defeats all the enemies, they will be rewarded with a new gun or item.

However, there are some risks involved with using the Altar. There is a chance that the player will receive a cursed item, which can have negative effects on their character. Additionally, any items sacrificed to the Altar cannot be retrieved, so players should carefully consider which items they are willing to part with.

Overall, the Altar is a high-risk, high-reward feature in Enter the Gungeon, and can be a useful tool for players looking to find more powerful weapons and items.
