Trivia

 * The ability will persist even when the Sword is removed from the user's inventory.
 * If a different weapon with is held with the ability active, its mana cost reduction will apply upon taking damage. If the Wither Cloak Sword has the  ability, it only applies its cost reduction while the Wither Cloak Sword is held.
 * During the Trial of Fire, the ability will trigger as long as the player's maximum  is above that of a single fire tick, preventing all damage. If the player has sufficiently high  (higher than ) and enough mana to survive the ticks (use a Mana Flux Power Orb or  as mentioned above), level 30 can be completed.
 * It was used in an exploit with a pickaxe to kill Ice Walkers while AFK. However, since the damaging effect of the veil has been removed, this exploit no longer works.
 * Sometimes, the charged creepers from the veil will persist if the user leaves the server while the veil is active. These charged creepers can be locked on to by the Flower of Truth, but otherwise have no effect.
 * Certain player interactions, such as shooting the veil with Runaan's Bow, can destroy the creepers.
 * Previously the Wither Cloak Sword's ability dealt damage (200 per second, depending on combat and Giant Killer level), but this was changed in the 0.11.3 update.
 * The Creeper Veil ability is able to nullify the damage from the Yang Glyphs in the Voidgloom Seraph boss fight, making it used to possible to semi-afk these bosses in combination with a Necromancy weapon, as well as prevent failing the quest when the Yang Glyphs were thrown into a wall(this has been patched) or somewhere unknown. The former one has been nerfed to almost impossible since Necromancy mobs now get despawned by Voidgloom Seraph.
 * Wither Cloak Sword can bypass the damage from Boomer Undead's TNT and Kalhuiki Tribe Members' fatal attack.
 * Wither Cloak Sword's ability will not take away any mana when used with Goblin Armor.
