Purity is an unlockable passive item.
- Grants an aura around Isaac that grants a boost depending on the aura's color.
- Red: +4 damage
- Blue: -4 tear delay
- Yellow: +0.5 speed
- Orange: +7.5 range, +1.0 tear height
- Taking damage causes the aura to disappear. When the next room is entered, the aura will reappear with a random color.
- The tear delay boost can allow the player's tears to go over the normal maximum rate of fire; see the tear delay explanation page.
- When picking up this item as The Lost, it is very difficult to change the boost since The Lost cannot take damage without dying. The only way to change this is if The Lost has multiple lives and dies or uses Dull RazorHurts Isaac without depleting health, activating any items that trigger upon taking damage..
