Until disturbed, Draguns prefer to sit atop mountains of ammo, jealously guarding their hoard.
All Draguns descend from Gunrax, the first Shelldrake. Though once thought to be invincible, it has been confirmed that the terrible creatures can be slain.
Drunkard Dialogue: "What? You've slain a great beast, deep in the Forge...? ... Could it be true? ... no. You must be lying."
Breathes a stream of fiery bullets towards the player, either sweeping the room or aiming at the player.
Pulls out two pistols and fires spreads of bullets in front, or rings to the front and sides.
Pulls out two Uzis and fires two streams of bullets which start by the edges of the room and move towards the middle.
Fires a rocket, which sends out a large ring of bullets upon colliding with the wall.
Fires several spreads of bouncing bullets.
Fires five homing skulls.
Summons fire bullets which travel down from either side of the arena and cross through the middle.
Throws large knives into either wall. The knives can be killed, and will continuously shoot a spread of bullets until they are killed.
Phase 2
Once he is at low health, he becomes invulnerable and completely fills the room with moving bullets. The player must dodge between circular safe zones.
Between each wave of bullets, his heart becomes exposed for a short time, during which he can be damaged.
Advanced Dragun

For an in-depth explanation of the Advanced Dragun phase, see; Advanced Dragun
If the player is in possession of the Serpent, after the first attack cycle of the Dragun's second phase, the Dragun will grab the Serpent and crush it- absorbing its power. Turning gold, the High Dragun will turn into the Advanced Dragun, restoring its health to full and beginning a secret third phase of the boss.
Tips
For the first phase, it is recommended to stay near the back of the arena, where most of the Dragun's attacks can be more easily dodged, aside from the Uzi attack.
The thrown knives should be taken out as quickly as possible as their attacks tend to overlap with the Dragun's attacks, leading to difficult situations.
Explosive weapons can be used in the second phase to get rid of some of the bullets for easier dodging.
The thrown knives can be blanked and completely removed before they land.
Item-Specific
Blasphemy can be used to thin the bullet breath so it is easier to roll through.
Blasphemy can also be used to enlarge the safe zones in the second phase.
With the right timing, the rocket can be destroyed with Blasphemy and the bullets will only fire in a semicircle.
The rocket can also be reflected with the last shot from the Finished Gun, presumably also being able to be reflected by Casey with the right timing.
If the player has Black Hole Gun, it can effectively negate all of the Dragun's attacks, as well as preventing knives from spawning. This is most effective combined with beam weapons, as they are not affected by the black hole.
Having Clone and dying on the last frame when you kill him soft-locks the game and you cannot continue the run.
Having Daruma here is useful, as dodging in the second phase allows the player to blank most of the rest of the attack away.
Positioning yourself behind Space Friend and Sprun in the second phase can allow it to block bullets and safely stay stationary for the entire phase.
Running out of ammo with the Directional Pad and standing behind the chest spawned allows you to safely stand still and block all of the bullets.
The Dragun's heart can still be damaged by the Baby Good Shelleton's laser even before it's exposed.

On 22/11/2018, Dodge Roll lead artist Joe Harty posted an unused Dragun animation to Twitter.[2] This animation was fairly rudimentary, with the Dragun wiggling its arms and neck in an unnatural way.
This unused item takes its name from the High Dragun, and appears to be a recolour of the Heart of Ice.
Notably does not resemble the Dragun's actual heart seen in battle.
Notes
After defeating the Dragun, its body will disintegrate into a skeleton. Its skull will drop onto the platform where the character stands, and the spine will form a bridge to the Aimless Void which houses the Gun That Can Kill The Past.
Once the player enters the Aimless Void, it's impossible to go back, so the player has to be careful to get Bullet That Can Kill The Past before they enter, if they need it.
If the player has Wax Wings, Jetpack, Ring of Ethereal Form, or another item that allows the player to fly and attempts to fly behind the Dragun, he will send down a wall of bullets that forces the player back towards the bottom half of the arena. This will happen regardless of whether the Dragun is actively doing an attack or not.
If the player has Challenge Mode active, the Dragun will always have Dragun Rage and High Stress active, which makes the Dragun much more difficult.
If the player has accumulated Curse, the knives thrown by the Dragun can be Jammed.
The hallway to the Dragun makes the vision zoom away from the player. If the player stops only a few steps from the animation, they can teleport into another room, keeping the vision zoomed out for an advantage.
The rocket he fires can be hit back with Casey, though it won't actually do any damage.
With Bloodied Scarf, the player can retreat off screen by dodge rolling downward at the corridor leading to the arena, which grants immunity to some attacks.
Any Items that are left in the Dragun's boss room will not be stolen.
Trivia
The High Dragun's Ammonomicon image is a reference to Smaug from The Hobbit.
The High Dragun hides in a mountain of shell casing (or the game's currency), similar to Smaug hiding in a mountain of treasure.
The High Dragun can be seen resting atop the Gungeon on the title screen.
However, in-game, he is in the Forge, the lowest level of the Gungeon.
When summoning the Dragun via a console or mods, killing it will softlock the game.
Bugs
Approaching the High Dragun's room to the point where the camera zooms out and warping away will result in the camera continuing to stay zoomed out.
