Dungeon Objects Guide (Mirrors, Black Market & Munchers)

A handful of interactive objects are scattered through the rooms of Enter the Gungeon. None of them go into your inventory, but each has its own rules, and using one in the wrong order or the wrong way can waste the opportunity entirely.

The sections below cover Mirror, Demon Face, Muncher, Evil Muncher and Heart Machine in that order, explaining how each is used, what it costs, and what to watch out for. Shrines are out of scope here — see the shrine list for what each one costs and gives.

Mirror

Mirrors show an unlocked chest in their reflection. Move your character's reflection next to the reflected chest and press interact to open it — this shatters the mirror and adds 3.5 Curse. Shooting the mirror also adds 3.5 Curse but makes the chest impossible to obtain.

• Reflected chests can be 흉내쟁이
• Reflected chests can be Glitch Chest, but without the usual glitch animation
• Freezing the mirror obscures the reflection, but the chest can still be opened normally
• Bullets do not appear in the reflection and cannot damage the reflected chest

Demon Face

Demon Faces are large green wall carvings that grant access to the Black Market. They can spawn on any floor except the Resourceful Rat's Lair, R&G Dept., and Bullet Hell.

Entry requires at least 1 Curse, or 100 탄피 on hand (or having held 100 that chamber). Without these, the Demon Face deals half a heart of damage and ejects the player. After the first visit, a teleporter spawns inside for permanent re-entry.

Inside, 공포탄 상인 – 올드 레드, 마녀 상인 – 커슐라, 액체 상인 – 구프톤 교수, and 열쇠 상인 – 플린트 each stock three wares at half price — the exception is 열쇠 상인 – 플린트, whose 열쇠-priced goods are not discounted. A corridor on the east side leads to a bonus 사격 게임 진행자 – 윈체스터 shooting range whose entry fee is also halved (see Winchester Minigame Guide).

Shooting water-based weapons (메가 도저, 사이렌, 배럴, 빙하, 거품총, 메가핸드, 스타퓨, 티어 저커) into the Demon Face's mouth yields a free random A 품질 or S 품질 gun or item, with no Curse or coin requirement; interactive water barrels and the 압축 공기 탱크 do not trigger it.

• While the 궁지에 몰린 자들의 지배자 is present, all merchants stop selling
• Merchants already met on the main floor may appear as duplicates in the Black Market
• Stealing in the Black Market only affects Black Market merchants, not the same merchants elsewhere in the run; one guaranteed steal is available per merchant (see How to Steal from Shops)
• During a Rainbow Mode run these four merchants have empty shelves, but the Demon Face can still be sprayed for its A 품질 or S 품질 reward

Muncher

Munchers appear near shops or in secret rooms throughout Enter the Gungeon. Feed them two guns and they produce one new gun in exchange.

등급 mechanics

The 등급 of the gun a Muncher produces falls between the 등급 of the two guns fed to it, inclusive. It will not normally produce a gun above or below that range — but if neither gun fed was S 품질, there is a 5% chance to receive a gun one tier higher.

Fixed combinations

The following combinations always produce a specific gun, regardless of 등급. Feed one gun from the first column and one from the second column to trigger the recipe.

Notes

• Munchers do not accept infinite-ammo guns, including the starter pistol, 군터, 케이시, and 결투 레이저
• A popped 풍선건 and a shattered 유리병 캐논 cannot be fed to a Muncher
• Feeding a 접착테이프d gun consumes both guns but counts as only one
• The order in which guns are fed does not affect the result

Evil Muncher

Evil Munchers are always found in the secret room of Bullet Hell. They can also rarely appear in secret rooms on other floors, and have a small chance to replace normal Munchers. Sometimes the secret room is shaped like a skull.

To unlock 건슬링거의 재, feed the Evil Muncher a total of 10 guns across any number of runs. Progress carries over between runs.

After 건슬링거의 재 is unlocked, the Evil Muncher consumes a random number of guns before spitting one back out; when it does, that gun is A 품질 75% of the time and S 품질 25% of the time. How many you need to feed before each payout is therefore unpredictable.

Notes

• Evil Munchers have a small chance to replace normal Muncher spots at shops
• Gun count progress carries over between runs — dying or leaving does not reset it
• Evil Munchers still produce guns on Rainbow Mode runs
• There is no known cap on how many guns an Evil Muncher can consume after 건슬링거의 재 is unlocked

Heart Machine

The Heart Machine stores 하트 pickups for later use when you are already at full health. When a heart drops and you are full, picking it up shows a "save for later" prompt and stores it in the machine instead of healing you.

The machine appears in shops and in elevator rooms leading to the next floor. The map interface shows how many hearts are currently stored. Stored hearts are only usable on the current floor — they cannot be carried to the next.

• When withdrawing, each 온전한 하트 is automatically split into two 반쪽짜리 하트s
• The 흡혈귀 NPC exchanges 반쪽짜리 하트 for 20 탄피 (multiplied by the current floor's price modifier)
• If full on health, clear the room first before collecting dropped hearts to avoid wasting them
