Stifling Dagger
Stifling Dagger icon.png
Throws a flurry of daggers at the area around the target point, each one hitting the first unit in its path. The daggers slow enemy movement speed, and deal 65 + 25%/40%/55%/70% of Phantom Assassin's attack damage as physical damage and applying attack effects from items and abilities.

Buff Stiflingdagger Caster: Dispellable with death only.
Debuff Stiflingdagger: Dispellable with any dispel.
The first skill learned by the Sisters of the Veil often signals an incoming hit.


  • Replaces the default Stifling Dagger.
  • Launches a dagger in 0.14 second intervals, starting immediately on cast.
  • The daggers are launched inaccurately, with a maximum spread distance of 100 upon reaching maximum length.
  • The daggers travels at a speed of 1200. Once an enemy comes within 50 range of a dagger, it disappears.
  • Upon hitting an enemy, the dagger causes Phantom Assassin to perform an instant attack on the target.
    • Since it is a regular attack, it can proc any attack modifier and on-hit effect normally.
    • Cleave effects are based on the target's position, damaging a circular area the opposite direction where the dagger came from.
    • Although the daggers may make it look like a ranged attack, the attack still counts as melee.
    • This means all abilities which differentiate between ranged and melee, use their melee effects/values, not ranged.
    • The performed instant-attacks have True Strike, so they cannot miss.
  • The daggers first reduce Phantom Assassin's total attack damage by the percentage, and then add their own 65 extra damage on top of that.
    • This results in the following formula: 65 + 25%/40%/55%/70% * (main attack damage + attack damage bonuses/reductions)
    • "Attack damage bonuses/reductions" includes all already existing attack damage changes, including temporary ones (Bash) and conditional ones (Quell).
    • The 65 damage is also an attack damage bonus, but is added after the main damage is calculated.
    • Attack modifiers which are based on attack damage (critical strike, lifesteal, cleave) include the 65 extra damage as well.
    • The damage is added to Phantom Assassin's attack damage through a status buff which lasts for 0.03 seconds.
    • Since the damage comes from a regular attack, it does not count as spell damage, but counts as attack damage.
    • This means it is affected by damage block, unaffected by spell damage amplification and cannot spell lifesteal.
  • The projectiles have 450 range flying vision. This vision lingers for 3.34 seconds at the target's location upon successfully hitting it.
  • When choosing the double strike Stifling Dagger talent, the spell launches a second projectile towards a random valid target within the cast range.
    • Cannot target the primary target with the second dagger, so when no other targets are nearby, nothing happens.
    • The secondary target is chosen randomly within the area. There are no priorities.

Phantom Strike icon.png
Teleports to a unit, friendly or enemy, and grants bonus evasion. If an attack is evaded while the bonus evasion is activated, Phantom Assassin has a chance to counter melee attackers with her own attack, and ranged attackers with a dagger of her current level of Stifling Dagger.
Cast Animation: 0.3+0.77
Cast Range: 1000
Evasion Bonus: 15%
Counter Attack Chance: 30%/40%/50%/60%
Duration: 4
Cooldown: 14/12/10/8
Mana: 50
Buff Phantom Strike: Dispellable with death only.
Mortred's silken veil is the last thing her unfortunate target sees.


  • Replaces the default Blink Strike.
  • Phantom Strike can be cast on allied units, still gaining the buff.
  • Moves Phantom Assassin next to the target, towards the position she was upon spell cast.
  • The evasion stacks multiplicatively with other sources of evasion.
  • When evading an attack with the evasion granted by Phantom Strike, Phantom Assassin has a chance to perform an instant attack on the attacking unit.
    • Other sources of evasion do not count. It must be evaded by Phantom Strike's evasion.
    • If the source of the evaded attack is more than 200 range away as the attack gets evaded, then a Stifling Dagger is thrown at the target.
    • The Stiflnig Dagger is based on the ability's current level, and therefore does not launch when not learnt.
    • Unlike a regular cast Stifling Dagger, which launches them in straight line, the ones from Phantom Strike home in on their targets. Has no range limit.

Can be used by illusions. Disabled by Break. Partially pierces spell immunity.
Blur icon.png
Phantom Assassin focuses inward, increasing her ability to evade enemy attacks, and allowing her to blur her body to disappear from the enemy team's minimap when far from enemy heroes.
Detection Radius: 1600
Evasion: 20%/30%/40%/50%
Partially pierces spell immunity. Detects spell immune heroes only when they gained spell immunity while already within the detection range. Already spell immune heroes entering the radius are not detected.
Buff Blur Active: Dispellable with death only.
Meditation allows a Veiled Sister to carefully anticipate her opponents in combat.


  • Modified values: None.
  • The evasion and the blur effect are independent from each other. The evasion is always active.
  • On average, Blur increases Phantom Assassin's survivability against physical attacks by 25%/43%/67%/100%.
  • Periodically checks for the presence of enemy heroes (including illusions) or creep-heroes and adapts its status.
    • When the blur effect is active, Phantom Assassin becomes blurry and a status buff is placed.
    • Detects invisible, spell immune and invulnerable heroes only when they gained the status while already within the detection range.
    • Already invisible heroes entering the radius are not detected, unless they get revealed by True Sight while within range.
    • Already spell immune or invulnerable heroes entering the radius are not detected either.
    • Detected invisible heroes remain detected until they get outside of the detection range.
    • Does not detect hidden heroes at all.

Coup de Grace
Coup de Grace icon.png
Phantom Assassin refines her combat abilities, gaining a chance of delivering a devastating critical strike to enemy units. Stifling Dagger shares the same critical strike chance.
Proc Chance: 15%
Critical Damage: 230%/340%/450%
Can be used by illusions. Red critical numbers are before illusion and armor reduction.
A divine strike, Mortred honors her opponent by choosing them for death.


  • Modified values: None.
  • Increases attack damage by an average of 19.5%/36%/52.5%.
  • The proc chances of multiple crit sources stack.
    • If two sources of critical strike proc at the same time, the higher multiplier has priority.
  • A part of the visual effects (a white glow on her weapon) plays during the start of an attack, revealing that the attack is going to crit.
