Behavior[ | ]
Attacks[ | ]
Phase 1[ | ]
- Sludgefield: spawns an area that slows you by digging closely below the ground after emitting an audible trigger to alarm the player.
- Towering: sticks his head out of the ground like a tower to spew indestructible projectiles in a fountain and create a bullet hell of destructible projectiles from the sky.
- Arcshower: he will jump over the player in an arc and shower them in projectiles
Phase 2[ | ]
In phase 2 The Boss will use the following attacks and all previous attacks:
- The seeing: his eyes will dislodge and be tethered to his head. These eyes can be killed and inflect the darkness debuff on contact.

Ophiocoon[ | ]
| Type | Boss Minion |
|---|
After Ophiopede has been defeated, the Ophiocoon will spawn carried by four Coocoon Carriers.
Behavior[ | ]
The four Coocoon Carriers will fly carrying the Ophiocoon to the opposite side of the world. The player must kill the Coocoon Carriers before they leave the map. Each Coocoon Carrier killed will cause the remaining Coocoon Carriers to struggle to carry the Ophiocoon. Once most of all of the Coocoon Carriers have been killed, they will drop the Ophiocoon which will spawn the Ophiofly. Failing to have the Ophiocoon dropped before the Coocoon Carriers to reach the end of the world will cause them to despawn, requiring the player to fight the Ophiopede again.
Tips[ | ]
- Fight and kill the Ophiopede on one end of the world. This will make it so the Coocoon Carriers will have to fly to the opposite side of the world, giving the player more time to defeat them.
- The Coocoon Carriers fly fast, high mobility is required to keep up with them.
- The Rod of Discord can allow the player to catch up.
- An Asphalt runway or skybridge will easily let the player keep up.
- The Ophiocoon will not attack the player, but the Coocoon Carriers will fire stingers at the Player. Players can opt for a max damage build for this segment to quickly defeat the Coocoon Carriers.

Tips[ | ]
- The Ophiofly has quite a lot of defense; armor penetration or armor reduction effects can greatly help in battle.
- Ichor (debuff) combined with Betsy's Curse will reduce enemy defense by 60. (Only 55 in 1.4.1)
- Shark Tooth Necklace will ignore 5 defense and the Sharpening Station will ignore 4 defense (12 in 1.4).
