D12#386

D12 is an unlockable activated item added in The Binding of Isaac: Afterbirth.

• The D12 is the only way in the game to remove metal blocks.
• Metal blocks can also be destroyed with Mega Mush.
• The original Antibirth mod had its own D12 that functioned similarly to this item. For obvious reasons, that item wasn't added in Repentance, although the D12's effect was updated in V1.7.8 to be more similar to the Antibirth version.

Bug! Using D12 while Tainted Forgotten is sitting over a pit (not being thrown) will make his head and weapon disappear, rendering him unable to attack and preventing Tainted Soul from picking him up, unless the room is left or the run is exited and resumed. This can easily cause a soft-lock. Bug! If D12 creates a Reward Plate in the boss room on the floor where an alt door is allowed to appear (After A Secret Exit is unlocked), activating the button to create enemies and kill will create another one, up to 4 doors (depending on the size of the room). Exiting the boss room will leave only the original alt door. By entering a copy of the door, you can go to the alt floor and if you exit, the original door will also be open, even if you did not open it. Bug! When rerolling obstacles while Isaac has 2Spooky; any Movable TNT or Fire Places spawned in the fear radius has a chance of being spawned momentarily feared with only the purple tint to indicate the status effect. This effect lasts even on the remains of either object after it's destroyed before the fear effect ends. Corn poops created in the radius are unaffected however the Eternal Fly may also become temporarily feared. Venus has the same bug with the only difference being that it is charming obstacles and Eternal Flys and turning them pink Dice Items
