The Binding of Isaac PS4 Patch 1.18 Notes – December 8, 2022

Changes

• The Cantripped! challenge now only spawns active item cards, item cards can be swapped out when picking up new cards when all card slots are already full
• Tainted Cain now has the same starting stats as Cain (increased damage and reduced range)
• Salvaging Tainted Cain’s active item no longer spawns special drops in special rooms (such as secret rooms)

• Great Gideon’s crawlspace no longer appears in the Ascent (as it crashed the game when entered)
• Expansion Pack can no longer trigger the Glowing Hourglass

• Updated a few item qualities
• Updated localization files

• Added Isaac.RunCallback(callbackId, entityId, …), runs all functions tied to the given callback and entityId (entityId can be nil for callbacks that do not depend on specific entity types)
• Isaac.AddCallback, Isaac.RemoveCallback and Isaac.RunCallback now accept any value as a callback ID, even non-numeric values such as strings, this may be used by mods to define custom callbacks for other mods to use
