Dioskouroi, the Twin Forces
Dioskouroi, the Twin Forces are a Pre-Hardmode boss fought after defeating Skeletron. The Dioskouroi are two separate entities, Castor and Pollux, each with its own attack pattern and health pool. Both must be defeated in order to defeat the boss.
Spawning
The Dioskouroi do not spawn naturally and are summoned using a Twincrux Pendant, which is acquired by interacting with the Spatial Disk after defeating Skeletron and The Vagrant of Space and Time.
Behavior
When spawned, Castor appears to the left of the player, while Pollux appears to the right. An arena appears around the player's position, preventing their movement beyond it. A special bar above the player appears, filling to the left or to the right depending on the player's position relative to the boss. If the left part of the bar is completely filled, the player will be affected with On Fire!. If the right part of the bar is completely filled, the player will be affected with Frostburn instead.
The Dioskouroi remain stationary throughout the fight, unless performing the Baleborn's Clash. They use a predetermined set of projectile attacks:
Castor | Pollux |

Exoflare | Freezing Azimuth |
Exoflare [cont.] | Chilling Hail |
Baleborn Clash | Baleborn Clash |
Rite of Ignition | Diamond Dust |

All of Castor's attacks inflict On Fire!
Pollux uses the following attacks:
- Baleborn's Clash: The Dioskouroi clash against each other, equalizing their health to whichever of the two had lower. This attack is always casted by both Castor and Pollux at the same time.
- Armory of Ice: Pollux summons frozen projectiles from above the arena that aim towards the player's position when casted, gaining speed as they traverse downwards.
- Freezing Azimuth: Pollux summons freezing projectiles from the top-right corner of the arena.
- Diamond Dust: Pollux creates two circle areas at the position of the player, dealing damage to the players caught in it when the attack is cast.
- Frozen Arsenal: Pollux creates several freezing projectiles from the top-left side of the arena, moving downwards.
- Chilling Hail: Pollux summons five freezing projectiles moving vertically downwards, with their position based on the position of the player.

Tips
- It is recommended to start the fight while slightly above ground, in order to gain maximised space for the arena.
- Since Clashing sets the Twins' health to that of the weaker one, it is best to focus hitting only one of the bosses.
- Pollux can harm Castor with his attacks and vice versa. Position yourself correctly while either of the two are casting their attacks to further increase your damage output.
Trivia
- The bosses' names are a reference to characters from the Percy Jackson book series.
