  • The projectile travels at a speed of 1800.
  • Applies a basic dispel in 0.2-second intervals, starting immediately as the debuff is applied, resulting in 25 dispel instances.
  • Nullifier first applies the dispel, then the debuff.
  • Can be cast on invulnerable units, applying the dispel and the debuff if the invulnerability can be dispelled.
    • However, if the invulnerability cannot be dispelled, the debuff cannot be applied, but can be refreshed, if already debuffed.
  • Despite the internal modifier's name, Nullifier does not mute the target.

Heroes with multiple units or high attack speed that can struggle against certain saves like Glimmer Cape icon Glimmer Cape and Ghost Scepter icon Ghost Scepter, but can not fit a Hex or a Eul's Scepter of Divinity icon Eul's Scepter of Divinity in their item build and maybe have to get the kill done in a small window of time.

  • Because this item has a short range and slow projectile speed, it is easier to land from a melee hero with a Blink Dagger icon Blink Dagger, Shadow Blade icon Shadow Blade or ability to close the distance.
  • A ranged hero may opt for a Scythe of Vyse icon Scythe of Vyse especially if they are an Intelligence hero. Note that Hex is dispellable with strong dispels.
  • Nullifier is strong against heroes with defensive items like Glimmer Cape icon Glimmer Cape, Eul's Scepter of Divinity icon Eul's Scepter of Divinity, Ghost Scepter icon Ghost Scepter and Aeon Disk icon Aeon Disk.
  • Since Force Staff icon Force Staff is dispellable, Nullifier will stop enemy heroes after they have been pushed a very short distance. This also works on Hurricane Pike icon Hurricane Pike's self-casting for the same reason, but not on enemy-casting (both pushes are undispellable).
  • Use it on heroes that use dispellable Buffs on themselves to escape or deal/prevent damage like Windrun icon Windrun and Flame Guard icon Flame Guard.
  • Nullifier icon Nullify is one of the very few debuffs that cannot be dispelled at all, making it useful against abilities with strong dispels, such as Dark Pact icon Dark Pact, Press the Attack icon Press the Attack, and Aphotic Shield icon Aphotic Shield.
  • Since Nullifier is undispellable, and has a visual effect, it may be useful against illusions in order to visually differentiate the original hero from them.
  • Unlike with other items, Nullifier cannot dispel Echo Shield from Lotus Orb icon Lotus Orb at all if Lotus Orb icon Lotus Orb is used first, and it can reflect it back to it's owner. So be patient before using Nullifier on an enemy hero protected by Lotus Orb icon Lotus Orb.
