美德之书

Template:Infobox activated collectible

Template:Cit

## Effects

* On use, spawns a wisp that orbits Isaac and fires small spectral tears alongside him. The wisps can block shots and deals contact damage to enemies, but take damage when doing so and will be destroyed when enough damage is taken.
	+ When a wisp is destroyed, the sound of fire being extinguished plays.
		- A normal wisp is white and blue, has 2 health and spectral tears which deal 1.6-2.4 damage, and is summoned in the middle ring.
		- A wisp's health can be represented by its size, shrinking as its health decreases.
		- Most wisps deal contact damage equal to 2x Isaac's damage. Doing damage this way usually destroys the wisp unless Isaac is invulnerable.
	+ Multiple wisps can exist at once. Some combinations have an upper limit of 26 wisps: an inner counterclockwise ring of 6, a middle clockwise ring with 8, and an outer counterclockwise ring of 12.
* If another active item is picked up, Book of Virtues will become a passive item that causes active items to spawn wisps when used, often with special effects.
* While held, changes the first Template:R encountered to be an Template:R, and increases the chance of an Angel Room appearing by 25%.
	+ Allows for Angel Rooms to appear even if a Deal with the Devil was taken before.
* Template:Transf

## Notes

* Template:C starts with this item.
* It is the only passive item in the library pool.
	+ If Isaac walks into a library for the first time with {{NO!}}, The Book of Virtues is very likely to appear.
	+ Because of this, when acquired from a library the book cannot be rerolled by use of the Template:I, Template:I, a Template:R, or getting hit as Template:C.
* Whenever Isaac is invulnerable the wisps are as well, but can still deal damage.
* Summoning a wisp while at the maximum will replace the most damaged wisp.
* While having 100% chance of Template:R discovery, Isaac will not get teleported to a Template:R by using some items which allow it. Instead, he will be teleported to the Angel Room, keeping his 100% chance of discovering Angel Room. This can be used to get to Angel Room on the first floor, where naturally Devil/Angel Rooms do not spawn, and still keep the 100% chance for the next floor.
* This item's passive effects also apply to active items in the consumable slot. (e.g. Template:C's Template:I, Template:C's Template:I, etc.)
* While the item can function as both passive and active item, it is treated as a passive item by {{NO!}}, Template:I and Template:P.
* This item is displayed in the Extra HUD as a passive item.
	+ It will take up one of Template:C's limited item slots.

	+ Template:I + {{Safety Scissors}}: Should the player find a single Golden Bomb in their playthrough, this theoretically allows infinite uses of Mama Mega! every floor, as the extinguished Golden Troll Bombs will turn back into Golden Bombs, allowing to repeat the process ad infinitum. Make sure to keep at least 1 wisp upon switching floors, however.

## No effect

These combinations simply activate the other item, some of them also spawning a normal wisp.

## Synergies

* {{Baby-Bender}}: Wisps gain homing tears.
* Template:I: Increases the tear size and doubles the damage of Wisps.
* {{Butter!}} / {{'M}}: Can be used to remove the Book of Virtues as long as Isaac isn't holding a different active item.
* Template:I: Doubles the spawned wisps on activation.
* Template:I: The wisps' tears are also detonated; the resulting tears are based on Isaac's own, rather than the wisps'.

## Interactions

* Template:I: Wisps are unable to shoot diagonally, and will shoot orthogonally instead.
* Template:I: The wisps' tears are attracted to the magnetic enemy, making it much easier to connect all of the wisps' tears on an enemy.
* {{NO!}}: Will not prevent Book of Virtues from spawning, as it's considered a passive item.
* Template:I: The Book of Virtues is considered to be a purely passive item, so only stat boosts will be gained by using Void on it. Further uses of the Void will not have the Book's effects.
* Template:P: Book of Virtues will be removed if it's the oldest collected item, even if another active item is not being held.

## Trivia

* Book of Virtues originates from the *Antibirth* mod, where it had a two-room charge but lacked the effect where it combines with other active items.
	+ Before that, it originated in the Community Remix mod for Flash Isaac, where it functioned like Template:I with a 6 room charge.
* This item is likely a reference to the 9 virtues of a person living in accord with the Holy Spirit, mentioned in Galatians 5.
* This is the only book item that can still appear if Isaac is holding {{NO!}}, due to being considered a passive item.
