Bladetongue

The Bladetongue is a Hardmode sword that has a 0.5% (1:200) chance of being caught while fishing in the Crimson. When it strikes an enemy, ichor streams are fired on an upwards arch, penetrating and damaging multiple enemies, bouncing against solid blocks, and applying the Ichor Debuff.

The best modifier available to the Bladetongue is Legendary.

Trivia
