The Biome Blade is a craftable Hardmode broadsword that auto-swings. The blade fires different projectiles that travel in a straight line, with effects depending on the biome the player is in.
The debuff the projectile inflicts depends on the biome the player is in and lasts 3 seconds:
If the player is in multiple biomes, then the higher one on the list above takes priority.
Its best modifier is Legendary.
- If a fired projectile travels into a different biome, the projectile will change into that biome's variant.
- Because almost all of its materials can be gathered Pre-Hardmode, it can be obtained as soon as the player obtains a Hardmode Anvil and Pearlstone Blocks. This, combined with its ability to shoot projectiles and apply powerful debuffs, makes it very valuable for melee players in early Hardmode.
