Prophets' Bane

The Prophets' Bane is Arbiter Thel 'Vadam 's personal energy sword. The blade's name is a testament to 'Vadam's staunch opposition to the Prophets' leadership ever since the latter days of the Human-Covenant War and the beginning of the Great Schism.

Gameplay
The Prophets' Bane is a playable melee weapon in Halo 5: Guardians and will be featured in the game's multiplayer beta at least on the map Truth. The weapon can be wielded exactly as a regular energy sword. However, the lunge attack has a greater range, effectively increasing the player's movement abilities.

Trivia
An achievement of the same name appears in Halo: The Master Chief Collection. It requires the player to complete every level of the Halo 3 campaign on Normal difficulty.
