How to unlock the Exorcist achievement in Enter The Gungeon - Definitive Guide

To encounter a Jammed Boss, you must have a high curse stat. Jammed Bosses do a full heart of damage on each hit and have increased health. The quickest way to encounter a Jammed Boss is:

1. Once you have beaten any character's past, start a new run.
2. Clear the first chamber until you find the boss room. Do not enter.
3. Teleport back to the starting room and pray at the statue, raising your curse stat to +9. You now have a very good chance of encountering a Jammed Boss. At this point, make sure you have a decent gun and whatever else you need.
4. If the first chamber boss is not Jammed, either (A) restart your run and repeat the process or (B) trudge on through the second chamber in hopes of meeting a Jammed Boss there.

Something I found on my attempt, although since he's random it's not TOO helpful, is that the Shadow Magician Miniboss counts towards this achievement. He's this fella https://enterthegungeon.gamepedia.com/Shadow_Magician

Even Jammed he probably has less HP than most other bosses. Plus his attacks are pretty easy to dodge, and he doesn't move around much. So at the very least he's another good reason to push through the second floor even if the first boss isn't jammed.

Another thing I've found is that, if the first chamber boss is the twins, only one of them needs to be jammed. Killing the jammed one earns you the achievement even if you die afterwards

The easiest way to do this is to kill a characters past. This will allow you to activate the statue at the beginning of the first level. By doing so? You max out your curse.

The way to do it is to finish the first floor and try to get a good boss killing weapon, like the sling. Once the floor is complete, head back to the statue and activate it. Now go to the boss room. The boss should be jammed. If not, rinse and repeat. The boss has the same move set and the first bosses are the easiest to dodge. The only difference being they will cause one heart of damage as opposed to the normal half heart.

In order to spawn any jammed enemies/bosses you need to raise your curse level. This can be done in a few ways: purchasing items from the sorceress if she appears in the shop, picking up cursed items from chests (they will emit a purple aura if they are cursed items), and stealing items from the shop (you will need an item like grappling hook or cardboard box to be able to do this). The more of these you do the more you will raise your curse level, and also increase your chances of running into cursed enemies and bosses. They all have the same attacks but will now deal a minimum of 1 full heart of damage per hit, and their attacks are more frequent so remember to play patiently against them!

A boss with black ammo like rare mobs is considered jammed. Bosses become like this if you take too many evil things. After completing the game with all 4 Persians, you can pray to the statue at the entrance and there will be a lot of black ones, in the end my 2nd boss was like this, I killed her, the reward is the opening of the 6th hall.

To interact with the altar, in order to receive 9 levels of curse (maximum 10), the character must go through his past. It is not necessary to go through with every character, the main thing is to kill the past with exactly the character you want to receive the curse from the altar.

You can also get a curse if you approach the cursed urn, it is blue. There are a lot of them, mostly on the second floor. I had 2 cursed items and I collected 7 urns, and as a result, a cursed boss fell on the 3rd floor. 1 urn is 1 level of curse; as for items, they can be from 1 to 2.5 and higher, depending on the combination. Under no circumstances should you gain a curse level of 10 or more, otherwise the Lord of the Jammed will rush after you everywhere, and you cannot kill him.

Jammed bosses appear with a certain chance from each curse. If you have 3 curses (need to be clarified), then the boss on the 5th floor will 100% be jammed. It's easiest to kill with platinum or silver bullets.
