Habit is a passive item.


  • When Isaac is hit, his active item gains 1 room's worth of charge.


  • Added in Afterbirth †Dull Razor Dull Razor + Added in Afterbirth †Schoolbag Schoolbag: Using the Dull Razor activates the Habit, but this does not restore its charge, only that of the item in the Schoolbag.
  • Yum Heart Yum Heart + 9 Volt 9 Volt: Isaac could potentially become invincible on early floors or with The Wafer, losing only half a heart per three hits taken.
  • Added in Repentance Sharp Plug Sharp Plug + The Battery The Battery: Isaac gains one charge from Habit for every half-heart of damage that Sharp Plug deals, effectively granting double the charges when using Sharp Plug.

In-game Footage[]


  • The Habit was significantly nerfed from the previous game. In the original game, it would restore half of Isaac's item's required charge rather than just one room's worth of charge. This could essentially make Isaac unkillable if it was used in conjunction with Yum Heart Yum Heart, The Nail The Nail, or Book of Revelations Book of Revelations and The Wafer The Wafer for The Womb Womb and beyond.
  • This item is used in When Life Gives You Lemons (challenge #12).
