Kamikaze!

Kamikaze! is an activated item.

Effect[]

Upon use, creates an explosion on Isaac's position.
- The explosion deals 40 damage.
- The size and damage of the Kamikaze! explosion is identical to that of a Mr. Mega bomb, dealing 185 damage in a wide radius.

Despite the explosion usually damaging Isaac, Kamikaze! is not stricto sensu considered a self-damaging item because it is not the item's use which causes the damage, but rather the resulting explosion. This has a few consequences:
- Kamikaze! does not bypass invincibility, which means items such as Holy Mantle or Tooth and Nail work normally.
- Using Kamikaze! will cause the sword summoned by Damocles to start having a chance to fall at any point.
Kamikaze!'s cooldown length is as long as the invincibility frames Isaac normally gets from being hit. This means that Isaac cannot activate Kamikaze!, and then activate Kamikaze! again before the invincibility frames end.
Synergizes with many bomb-enhancing items such as Bob's Curse, with exceptions listed in Interactions.

Blind Rage: With longer invincibility, Isaac can use Kamikaze! a second time without taking damage.
Book of Virtues: Spawns wisps in the middle ring that looks like small sticks of dynamite. The wisps fire explosive projectiles and explode when destroyed, dealing 30 damage to enemies that are close to it. This explosion is small enough to not always hit Isaac, although it will hurt him should he get caught in it. All explosions the wisps make are unaffected by BFFS! and bomb synergies.
Dark Arts: Kamikaze can be used for free while Dark Arts is active.
Gnawed Leaf: Activating Kamikaze will cancel out of the statue state, but Isaac will not be damaged by the resulting explosion.
Host Hat / Pyromaniac: Allows unlimited uses without consequences.
- Pyromaniac: Each use will heal Isaac for one full / half a red heart.

Mars: Isaac is invincible during the dash, allowing for unlimited uses with careful timing.
Panic Button: Isaac will use Kamikaze before taking damage, similarly to Swallowed M80, with the exception that, if Kamikaze triggers on red health, it will not affect devil/angel deal chances, effectively preserving it.
Schoolbag: The cooldown before the player can use Kamikaze! again is eliminated when switching items. Depending on how fast the player can push the buttons, Kamikaze! can be used multiple times during Isaac's invincibility frames.
Tainted Forgotten: Explodes on Tainted Forgotten’s body, meaning that it is safe to use infinitely so long as Tainted Soul is not within the blast radius.

The following items have no effect:
Jacob and Esau: Only the brother using it will take damage, regardless how close the other is to the blast.
Strawman: Keeper will take damage if he's caught within the blast radius.

The term kamikaze comes from the Japanese language (神風, divine wind), and refers to Japanese pilots that would blow up their aircraft and themselves to damage enemy targets during World War II.
This item is used in Blue Bomber (challenge #23).
