3. Hero Skills Breakdown

1. Fortune's End

Nerif channels his arcane power into a bolt of scouring energy. Upon release, the bolt strikes the target, dealing damage to enemies and triggering a purge effect in a radius around the impacted unit, rooting them for a duration scaled by the time spent channeling.

  • Damage Type: Magical
  • Mechanic: Channeling projectile with an area-of-effect purge
  • Root: Freeze/Root status (Purge)
Level Magical Damage Cooldown Manacost
1 100 15 seconds 100
2 160 12 seconds 100
3 220 9 seconds 100
4 280 6 seconds 100

2. Fate's Edict

Nerif enraptures a target, rendering them completely unable to launch physical attacks while simultaneously granting them near-total immunity to magical effects. This can be cast on either allies or enemies.

  • Mechanic: Disarm and Magic Immunity buff
  • Aghanim's Scepter Upgrade: Applies only the disarm when cast on enemies and only the magic resistance when cast on allies
Level Duration Cast Range Cooldown Manacost
1 3.0 seconds 500 units 16 seconds 50
2 3.5 seconds 600 units 13 seconds 50
3 4.0 seconds 700 units 10 seconds 50
4 4.5 seconds 800 units 7 seconds 50

3. Purifying Flames

Nerif burns away impurities from a target unit. This process deals significant damage initially, but compensates by providing a rapid, continuous healing effect over time.

  • Damage Type: Magical
  • Mechanic: Damage-followed-by-healing buff
Level Magical Damage HP Regeneration per Second Cooldown Manacost
1 90 11 2.25 seconds 80
2 180 22 2.25 seconds 85
3 270 33 2.25 seconds 90
4 360 44 2.25 seconds 95

4. False Promise

Nerif alters the destiny of a target ally, forcing all incoming damage, healing, and regeneration effects to be delayed until the promise expires. This effect also removes negative status effects upon cast.

  • Mechanic: Damage/Healing delay
  • Exclusion: Cannot prevent damage from specific "killing blow" abilities
  • Unique Interaction: Healing provided during the delay is doubled at the end of the duration
Level Cast Range Duration Cooldown Manacost
1 700 8 seconds 120 seconds 100
2 850 9 seconds 90 seconds 150
3 1000 10 seconds 60 seconds 200

4. Item Build Guide

Phase Recommended Items Strategic Purpose
Early Game Tranquil Boots, Magic Wand, Soul Ring Tranquil Boots provide essential HP sustain. Magic Wand helps in narrow escapes, and Soul Ring fuels your frequent spell rotations.
Core Items Aether Lens, Aghanim's Scepter, Force Staff Aether Lens is vital for casting your spells from safety. Aghanim's Scepter greatly improves the utility of Fate's Edict, and Force Staff adds necessary defensive mobility.
Late Game Scythe of Vyse, Ghost Scepter, Guardian Greaves Scythe of Vyse offers game-changing lockdown. Ghost Scepter keeps you alive against physical damage, and Guardian Greaves provide a mass purge and heal for your team.

5. Quick Gameplay Tips

  • The Purification Combo: You can deal heavy damage to enemies by using Purifying Flames multiple times in quick succession. If you cast Fate's Edict first to provide magic resistance to an ally, you can follow up with Purifying Flames to heal them without dealing damage to them. Alternatively, use Purifying Flames twice on an enemy for a massive burst of magical damage.
  • False Promise Timing: Do not wait for an ally to reach 10% health to cast False Promise. The spell removes negative status effects upon activation, so it is often better to use it pre-emptively when a key ally is being focused by CC or burst damage. The delayed healing doubled at the end makes this one of the strongest "save" abilities in the game.
  • Purge Positioning: Fortune's End can be a reliable setup for your team. By channeling the bolt, you can hold an enemy in place for a significant root duration. Coordinate with your team so that you channel the purge as an enemy is attempting to flee, ensuring they are rooted in a location where your allies can easily follow up with their own disables.
