Craig's Battery is an active item in Fiend Folio: RELOADED, a mod for The Binding of Isaac.

Only has an effect when playing as Craig. Attempting to use it as any other character will only allow its passive effects to work.

Craig's Battery has a total of 300 charges, and it can be used when at least 1/3rd full.

These charges are filled up by dealing damage to enemies, interacting with Bulb Rocks, or picking up Bulb Lanterns.

The amount of charges filled is as follows:
• +10 damage per enemy hit.
• +2 per frame (+10 per second) while standing next to a Bulb Rock.
• +120 for touching a Bulb Rock.
• +30 for picking up a Bulb Lantern in its first growth stage.
• +75 for picking up a Bulb Lantern in its second growth stage.
• +150 for picking up a Bulb Lantern in its third growth stage.

The item can be overcharged. Fully overcharging the item will cause an explosion that deals 100x Craig's damage. This explosion also damages Craig and fully discharges the item.

While in a cleared room, Craig's Battery is constantly drained.

On use Craig insta-charges a yellow Brimstone-like laser that can be fired in the chosen direction by using the shooting keys.

The laser will either be thin or thick based on whether Craig's Battery is fully charged or not.

The laser lasts for 0.33 seconds, and deals damage equal to DamageStat ^ TotalCharges, 15 times per second. This damage is increased by x1.5 if the laser is thick.

While held Causes Bulb Lanterns to grow randomly inside uncleared rooms. Up to 5 Bulb Lanterns can grow in a room at the same time.

Bulb Lanterns have 3 stages of growth (tiny, medium, full), each taking 3.33 seconds to grow.

The Bulb Lanterns are immediately destroyed upon clearing the room.
