Item: Dead Onion
+5 bombs. Isaac's bombs will now explode in a large cross-shaped pattern (roughly 5 bombs explosions wide). This also affects troll bombs.
Increases damage by 1, range by 5.25, and tear height by 0.5.
Increases speed and reduces character size. Also gives a random pill.
An orbital angel which does 7 contact damage per tick and blocks enemy shots. Upon blocking 10 shots in a room it drops an eternal heart.
Increases Damage and Speed, plus adds one Soul Heart.
Spawns a familiar that floats slowly around the room on a zig-zag pattern similar to Boom Fliesdamaging enemies it passes through.
+0.3 tears up. Allows Isaac to fire tears diagonally.
Gives Isaac 5 bombs, and makes all dropped bombs larger, which have an increased blast radius and increased damage.
Creates a ring of light around Isaac that petrifies enemies in contact.
Fires lasers at any enemy in its line of sight and moves based on the direction Isaac is firing tears.
Replaces Isaac's tears with eyeballs that can bounce off of each other. The eyeballs are not limited by range, and will instead dissipate when they stop moving or when hitting an enemy or obstacle.
Randomly while firing tears, Isaac will stop firing and turn red, where he will charge and release a lot of 'tears' in one go. In the burst of tears is a kidney stone which deals a lot of damage.
Upon picking up a certain amount of health, spawn a permanent angelic familiar.
Curse of the Tower
Causes Isaac to spawn 6 troll bombs on the floor every time he gets hit, similar to the Anarchist Cookbook mechanic.
Grants a prism orbital with a large orbital radius. Tears that pass through the prism split into four multi-colored tears.
While firing tears, Isaac has a chance to fire an eye across the screen with a very slow shot speed, which will fire tears of its own in the same direction as Isaac. The eye will be destroyed if it comes into contact with an enemy or obstacle.
Tears are replaced by bombs that benefit from bomb-enhancing effects and slide a fixed range after being fired.
Grants piercing and spectral tears. Increases tear size (without increasing damage) while greatly reducing range and shot speed.
