AMMONOMICON

Ammo Shrine

+3.5 Curse

A shrine to Shell'tan, ammo elemental.

Instantly refills the ammo of every weapon you are carrying.

Angel Shrine

+1.5 Curse

A shrine to a prideful bullet angel, now fallen.

Sacrifice a heart container (or two armor as The Robot) to permanently increase your damage by 25%.

Beholster Shrine

A shrine to the Beholster, the sphere of many guns.

Offer the six guns the Beholster wields — Com4nd0, M1911, Void Marshal, Machine Pistol, Eye of the Beholster, and Trank Gun — across multiple runs. Once all are given, they return with the Behold! synergy, orbiting you and firing at nearby enemies.

Blank Shrine

"...offering..." — the rest of the text is blank.

Using a Blank next to the shrine has a 90% chance to spawn a chest. Each chest received lowers the odds by 45% (minimum 25%). Chests may be locked, unlocked, or a mimic.

Blood Shrine

An ominous fountain, filled with blood. It isn't quite full...

Sacrifice a heart container (or two armor as The Robot). Nearby highlighted enemies are worn down by a damaging aura that heals you once you've drained enough. Using it twice unlocks the Life Orb.

Challenge Shrine

Dark energy permeates this shrine, filling you with foreboding.

Fight through three waves of enemies. Survive them all to earn a reward chest — which may be a mimic. Moving on before challenging it may make the shrine vanish.

Cleanse Shrine

Curse → 0

The spectres draw closer the more your curse grows.

Resets your Curse to 0 for a price of 5 money per point of curse removed. Generates in its own room with a unique icon on the map.

Companion Shrine

A statue commemorating the few friendly faces met in the Gungeon.

Sacrifice a heart container (or two armor as The Robot) for a random familiar-summoning item. Companions stack, so you can gather several.

Dice Shrine

A shrine to Icosahedrax, the great arbiter.

Rolls one positive and one negative effect at once — healing, money, blanks, armor, or chests paired with a harmful opposite. A rare 0.1% roll makes it explode: heart containers drop to 1, but your damage quadruples.

Glass Shrine

A shrine of glass.

Grants three Glass Guon Stones that orbit you and block enemy bullets, but shatter the instant you take damage. The first use unlocks the Glass Guon Stone item.

Hero Shrine

Sets Curse to 9

"Kill your past; you've already damned your future."

Found in the Keep of the Lead Lord's starting room, usable only after killing your past. Sets your Curse to 9 for a high-risk, high-reward run. Cannot be used if your curse is already 9 or higher.

Junk Shrine

A shrine to Ser Junkan, who rose from nothing to knighthood.

Trade Junk to the shrine in exchange for a piece of armor.

Peace Shrine

A shrine to a forgotten bullet who laid down his arms... will you?

Heals one heart in exchange for your currently held weapon. On a Blessed run, guns can be traded for hearts again and again.

Y.V. Shrine

A shrine to the Gun Godz.

Costs 10 money the first time, rising by 10 each use. Grants a chance for every shot to fire 2–4 extra bullets at no ammo cost. Each use raises the proc chance by 3.7%.
