  • Removed in Repentance The D12 is the only way in the game to remove metal blocks.
    • Added in Repentance Metal blocks can also be destroyed with Mega Mush Mega Mush.
  • Antibirth, the mod that originally inspired the new content in the Repentance DLC had its own D12 that was identical in all ways except for a slightly different sprite. For obvious reasons, this item wasn't added in Repentance.

Bug Bug! Added in Repentance Using D12 while Tainted Forgotten 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 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.
