Item: Dull Razor
When used, copies the effect of the pill Isaac is currently holding without consuming it. Does not copy the effects of cards or runes.
Upon use, rerolls all passive items on Isaac like the D4, every pedestal item in the room like The D6, and every pickup like the D20.
Monstro jumps onto a random enemy, doing area damage. Can damage/kill the player if summoned in an room without enemies.
Isaac holds the axe above his head for as long as the spacebar button is held (or until he leaves the room). While holding the axe, Isaac can break any rock he touches, but cannot attack or pick up other items.
Breath of Life
Grants a brief moment of invincibility when the charge bar hits zero. If spacebar is held for an additional second after hitting zero, Isaac will take damage.
The Book of Sin
Spawns a random pickup, pill, card, or trinket.
Kills all enemies in the room, then kills Isaac three seconds later.
Freezes all enemies until a fire button is pressed.
Upon activation, Isaac loses a half-heart (one whole heart in The Womb onwards) for a random amount of coins, similar to the blood donation machine.
Rerolls the enemies in a room. Only rerolls enemies that are still alive (does not spawn new enemies).
When used, will detonate any tears currently on the screen and cause each one to split into 6 more tears which will fire in a circle, similar to Tammy's Head.
Head of Krampus
Fires a cross-patterned brimstone shot, just like The Fallen and Krampus shoot.
When at full health, up to 4 extra hearts can be stored in the jar.
Damages all enemies in the room, but deals a heart of damage to Isaac with each use.
Upon use, for the next two seconds, any enemy shots that come near Isaac are held in place. After the charge is depleted, they are fired back as tears.
Damages all enemies in the room and slows them and their projectiles down.
Upon use, Isaac fires a laser similar to the one used by Mega Satan. This laser deals massive damage, lasts for approximately 15 seconds, and persists between rooms. Isaac is pushed backwards by the force of the laser while it is active.
