Bag of Crafting is an unlockable activated item added in The Binding of Isaac: Repentance.
Contents
Effects[]
- Upon use, pressing an attack direction will cause a swipe attack with high knockback and 3 damage.
- The swipe scales in size with Isaac's size.
- The swipe will appear further from Isaac the higher his range is.
- The swipe can be used to open
Spiked Chests and
Mimic Chests without taking damage.
- The swipe can be used to block bullets.
- Swiping a pickup on the floor will add it to the bag. The bag's contents cannot be dropped. Up to 8 pickups can be stored.
- Double pickups like Double Hearts will add two copies to the bag. Blended hearts will add one red heart and one soul heart.
- Sticky nickels can't be picked up unless unstuck.
- Chests and sacks can't be picked up, but can be opened with a swipe even behind obstacles.
- If Isaac has enough money to buy a pickup from a
Shop, using Bag of Crafting on that pickup will purchase it and automatically add it to the bag.
- Once 8 pickups are held in the bag, the bag can be used once more to spawn an item pedestal.
- If a recipe would result in an item that hasn't yet been unlocked, a random item will be crafted instead.
- There are a total of 29 different types of consumables that can be placed in the bag. The ordering does not matter for the outcome.
As Tainted Cain:
- If pickups are collected after the max of 8 is reached, the contents shift left and up, deleting the top left slot and adding at the bottom right. Tapping the switch key cycles the bag's contents left and up in a loop, making it possible to choose which pickup to overwrite.
- Once 8 pickups are held in the bag, the bag will show a preview what would be crafted. Holding down the Use Pill/Card button will craft the item and place it directly in Tainted Cain's inventory.
- Crafting an activated item while already holding one will turn the old one into pickups like collecting it would.
Curse of the Blind hides the crafting preview.
Component Types and Qualities[]
The cumulative quality of the components impacts the quality of the item received. The pickups belonging to each component type and their qualities are listed as below. The item received can be from the Treasure Room item pool (1× chance), Shop item pool (2× chance), Boss Room item pool (2× chance), or one of the pools listed in the table below. The pools in the table below require at least 1 of the corresponding component. For example, Devil Room items require at least 1 Black Heart.
If the recipe chooses an item from Devil, Angel, or Secret Room pools, the total component quality is lowered by 5 before the resulting item quality, and consequently the resulting item, is determined.
