Dim Bulb is a trinket added in The Binding of Isaac: Afterbirth † expansion.
Effects
- Increases all stats while Isaac's active item is completely uncharged:
- +0.50 speed
- +1.50 range
- +0.40 tears
- +0.30 shot speed
- +1.5 damage
- +2 luck
Notes
- Dim Bulb is more than twice as powerful as
Vibrant Bulb; however, its effects are active less frequently. - One time use items without a charge bar like Mama Mega! count as uncharged and provide the bonus.
- Dim Bulb has no effect when no active item is held.
- If the player has 2 items (via Schoolbag), only 1 of them needs to be empty to receive the benefits.
