Heroic Edge is a type of Artifact in the Rogue Legends DLC for Bloons TD 6, introduced in version 48.0. It grants Heroes a 10% chance to release three homing swords that seek out and damage Bloons. Despite the wording referencing projectiles expiring, this artifact still functions with heroes lacking traditional projectiles such as Sauda or Psi and the sword damage increases with the Artifact's rarity. It also grants a pierce bonus to non-Hero Monkeys of +25% despite what the Artifact description says. The swords can re-hit Bloons after 0.5s and cannot hit Camo Bloons unless its parent tower has Camo detection. Joan of Arc Adora starts with the Common version.

The swords from Heroic Edge are cleared at the end of the round and use Adora's seeking mechanics for one second after spawning before moving on a straight line afterwards.
During the early game this Artifact can be used to catch stray Bloons that escape the Hero's range, but shouldn't be relied on for general defense so this Artifact is mainly used for the general pierce bonus until the late game where the player has enough attack speed buffs so the Heroes can summon a large amount of swords that can actually represent a significant amount of damage. General buffs to Heroes are harder to obtain so using artifacts like Heroic Specialty and Essence Of Dreadbloon are recommended so they can receive buffs intended for other Monkey categories.
