Omega Biome Blade

The Omega Biome Blade is a craftable post-Moon Lord broadsword that auto-swings and is an upgraded version of the True Biome Blade. It fires different projectiles based on the biome in which the player is in, with the secondary change of such based on a moon event. The projectiles home in on enemies. All debuffs and buffs inflicted by its projectiles last 10 seconds.

If the player is in multiple biomes, then the higher one on the list above takes priority. The moon events are calculated independently, therefore they will stack with each other as well as one debuff depending on the player's biome.

Its best modifier is Legendary.

  • If the player travels into a different biome after a projectile is fired, the projectile will change into that biome's variant.
