"A failure of twisted scientific ambition..."

The Dragonfolly is a post-Moon Lord boss fought in the Jungle.

It drops Effulgent Feathers, which are needed to craft the Dragon Egg, the item that summons Jungle Dragon, Yharon, as well as the Silva armor set.

Spawn

The Dragonfolly can be spawned by the player using Exotic Pheromones in the Jungle.

Behavior

The Dragonfolly is a very fast boss, often aligning itself vertically with the player to horizontally sweep across them. It will occasionally slow down and perform other attacks, including summoning projectiles around the player and spawning servants.

If the player moves at least 75 tiles away from the boss or exits the Jungle biome for at least 3 seconds, The Dragonfolly will each gain a level of enrage, gaining increased aggression and feather speed. If both conditions are met, the boss gains 65% more DR and causes two lightning pillars to summon when a Lightning Flare Orb is fired.

Attacks

Phase 1

Lines up vertically with the player and performs a long horizontal charge into them. The duration between charges are relatively random.
Occasionally pauses to summon 6 Red Lightning Feathers around the player, which converge on their position before slowly homing in on them. When they get close to the player, they will slow down before launching themselves ahead of where they were moving. Then, up to two Draconic Swarmers are spawned, which are slightly more aggressive than natural.
- The attack will not perform if two Draconic Swarmers are alive, and only one will be summoned if there is one alive.

Phase 2

Transitions at 50% / 75% life.
Gains a bright red glow in its eyes and wings.
Performs shorter charges at the player and summons 3 lightning feathers around them every time it charges.
Summons 5 lightning feathers instead of 6 in the paused attack.
Will occasionally stop to fire a lightning flare orb that erupts into a pillar-like Red Lightning Aura on contact with the player or a surface. The pillar deals contact damage and summons lightning from the sky as long as the player is in contact with it.
- The Dragonfolly will gain 75% DR when performing the attack.

In Expert Mode

Significantly increased charge acceleration.
The Dragonfolly gains a new phase at 10% / 25% / 40% life.
- Its whole body glows bright yellow.
- Loses the ability to spawn Draconic Swarmers.
- Performs even shorter charges.
- Summons 4 feathers instead of 3.
- Flare orbs cause two pillars to appear on either side of the player regardless of enrage.

In Revengeance Mode

Enters Phase 2 at 75% life and Phase 3 at 25% life.
Up to three Draconic Swarmers can be alive at once.

In Death Mode

Enters Phase 3 at 40% life.
Increased speed and aggression.

Aftermath

The Witch Doctor begins selling the Exotic Pheromones.

Notes

The Dragonfolly's damage reduction works differently from other bosses. Cursed Inferno reduces its DR by 10%.
- This reduction is multiplicative. As such, when under the effects of Cursed Inferno, its DR is 9% instead of 8%.

Tips

For more elaborate strategies on defeating The Dragonfolly, including weapon and arena recommendations, see Guide:The Dragonfolly strategies.

The Dragonfolly is incredibly quick, making high acceleration and max speed a must.
Focus on The Dragonfolly as much as possible. Defeating the Draconic Swarmers is futile, as more will easily spawn in their place.
Circling the Swarmers is an effective way to avoid being hit, as they reduce in speed when changing direction. Make sure to dodge the feathers, however, as they can easily swarm the player.

Trivia

The Dragonfolly's theme is Murderswarm, which was composed by the artist DM DOKURO.
- This theme contains a motif from the Jungle Dragon, Yharon's first phase theme.
- If the Calamity Music add-on mod is disabled, Boss 4 will play instead.
The Dragonfolly's health is exactly 10% of that of Yharon. This references its status as a failed clone of Yharon.
This boss was previously named "Bumblebirb".
- This previous name is a combination of "bumblebee" and "bird", which, given the lore's mentioning of their incredibly high reproductive rates, may be a reference to the phrase 'The Birds and the Bees'.
- The term 'birb' comes from an internet meme.
- The rename occurred due to a resprite and coinciding fight rework, making the boss less resemble a bumblebee and generally becoming more serious in nature.
  - This is also more in-line with the lore, as it makes sense that the failed cloning experiments would result in a dragon rather than the Bumblebirb.
In the mod's source files, it is referred to as "Bumblefuck".
