Talent Tree Structure

Mobile Legends Bang Bang Assassin Emblem talent tree with Master Assassin and Killing Spree

  • Tier 1: Rupture (+5 Adaptive Penetration)
  • Tier 2: Master Assassin (+7% damage vs isolated heroes)
  • Tier 3: Killing Spree (15% lost HP recovery when below 30% HP + 20% movement speed for 3s after kills, 30s cooldown, resets on kills)

March 19, 2025 buff increased Killing Spree's HP recovery from 8% to 15% and movement speed from +10% (5s) to +20% (3s).

Why This Matters

Solo junglers (Fanny, Hayabusa, Joy, Ling, Suyou) need emblem optimization for farm efficiency and kill securing. Master Assassin excels in 1v1s; Killing Spree rewards elimination chains. Choice directly impacts Mythic/Mythical Glory win rates.

Master Assassin: Mechanics

Activates when only one nearby enemy hero is present. +7% damage applies to all damage types (physical, magical, true). No cooldown—permanent passive.

Damage Calculations

+7% multiplier applies after base damage, before armor/magic resistance reduction. Example: 2,000 base damage gains 140 points with Master Assassin active.

Synergy heroes:

  • Hayabusa: Ultimate guarantees isolation
  • Lancelot: Mobility creates separation
  • Gusion: Burst combo benefits from amplification

Activation Conditions

Requires exactly one enemy hero nearby. Minions, jungle monsters, summons don't affect activation. No cooldown restrictions—functions continuously.

Best Heroes

  • Hayabusa: Ultimate guarantees isolation, playstyle revolves around solo eliminations
  • Fanny: Cable engagements create 1v1 scenarios
  • Lancelot: Hit-and-run tactics separate targets
  • Gusion: Burst window aligns with instant activation
  • Benedetta: Dueling during split-push

Killing Spree: Analysis

Recovers 15% lost HP when securing eliminations below 30% health + 20% movement speed for 3s. 30s cooldown resets immediately on kill/assist.

March 19, 2025 buff made it meta-defining: HP recovery doubled (8%→15%), movement speed doubled (+10%→+20%).

Activation System

Binary trigger—no stacking. Activates instantly on elimination below 30% HP. 15% lost HP recovery scales with max HP pool.

Jungle Clear Synergy

+20% movement speed accelerates rotations between camps. 3s duration reaches next camp or repositions for ganks. HP recovery enables aggressive counter-jungling and escape.

Optimal Heroes

  • Ling: Extended teamfights, chains eliminations, wall-hopping synergy
  • Hayabusa: Ultimate secures kills, recovers HP post-shadow form
  • Aamon: Invisibility controls engagement timing
  • Karina: Ultimate resets synergize with talent resets

Early Game (Levels 1-7)

Master Assassin: Dominates isolated jungle/river fights. +7% active at level 4. Increases damage per engagement by 5-8%.

Killing Spree: Minimal impact—junglers rarely drop below 30% HP. Activates in ~15-20% of early fights. Value emerges at first Turtle.

Winner: Master Assassin for burst assassins prioritizing early kills.

Mid Game (Levels 8-12)

Killing Spree: Ideal for 3v3/4v4 teamfights around objectives. 15% recovery restores 200-300 HP at level 10. Reset mechanic shines.

Master Assassin: Maintains value but grouped scenarios reduce uptime. Flanking/split-pushing preserves effectiveness.

Context-dependent: Hayabusa (assassination) = Master Assassin; Ling (teamfights) = Killing Spree.

Late Game (Level 13+)

Killing Spree: Favored in 5v5 teamfights. Survivability enables focus fire survival, elimination securing, escape. Mythical Glory data shows 12-15% higher survival rates.

Master Assassin: +7% faces diminishing returns vs defensive items. Requires built-in survivability (Benedetta) to remain effective.

Winner: Killing Spree for most assassins in late-game teamfights.

Match Data (1,000+ Mythic+ Games)

Mythic rank stats chart for Master Assassin and Killing Spree Mobile Legends Bang Bang

  • Master Assassin: 8.2 kills, 4.1 deaths, 52.3% win rate
  • Killing Spree: 7.9 kills, 3.3 deaths, 53.1% win rate

Hero-specific:

  • Lancelot: 54.7% (Master Assassin) vs 51.2% (Killing Spree)
  • Ling: 55.8% (Killing Spree) vs 50.9% (Master Assassin)

Hero-Specific Recommendations

Burst Assassins: Master Assassin

Lancelot: Immunity frames + burst combo create isolation. +7% ensures combo eliminates squishies. High mobility compensates for no movement speed bonus.

Gusion: 2s skill combo window benefits from instant amplification. Either eliminates or dies—HP recovery irrelevant.

Benedetta: Shield provides survivability. Master Assassin enhances dueling during split-push.

Sustained Dealers: Killing Spree

Ling: Extended teamfights, chains eliminations. HP recovery + wall-hopping mobility = uncatchable. Reset mechanic perfect for his kit.

Aamon: Invisibility enables precise health management. Engage below 30% HP, secure kill, recover while invisible.

Karina: Ultimate resets + Killing Spree resets = continuous activations. Snowballs through teamfights.

Hybrid: Context-Dependent

Hayabusa: Tanky comps = Killing Spree; squishy lineups = Master Assassin. Versatile enough for both.

Natalia: Invisibility ganks favor Master Assassin for guaranteed isolation during basic attack burst.

Fanny: Special Case

Cable mobility creates isolation (favors Master Assassin), but vulnerability during cooldowns benefits from Killing Spree. Advanced players prefer Master Assassin for aggressive early invades; defensive players choose Killing Spree for teamfight survival.

Equipment Synergy

Recommended equipment for Assassin Emblem talents in Mobile Legends Bang Bang

Master Assassin Items

  • Hunter Strike: +15 penetration, +80 attack. Movement speed compensates for no Killing Spree mobility.
  • Blade of Despair: +160 attack amplified by +7%. Passive synergizes with assassination.
  • War Axe: Stacking attack/penetration scales Master Assassin throughout fights.

Killing Spree Items

  • Oracle: Increases max HP, amplifies healing effects. Synergizes with 15% HP recovery.
  • Immortality: Second life + reset mechanic = escape or continued fighting post-resurrection.
  • Brute Force Breastplate: Movement speed stacks with +20% bonus. Defensive stats increase HP pool.

Penetration Priority

Master Assassin: Prioritize penetration (Hunter Strike, Malefic Roar) to bypass armor. Attack speed minimal value.

Killing Spree: Can incorporate attack speed (Corrosion Scythe) for sustained damage. Penetration still important vs tanks.

Universal Cores

  • Endless Battle: True damage amplified by Master Assassin. Lifesteal + movement speed for both configs.
  • Thunder Belt: HP + slow creates isolation (Master Assassin) or improves recovery amounts (Killing Spree).

Situational Selection

Enemy Composition

Squishy/spread-out (multiple marksmen/mages/support): Master Assassin. +7% reliably eliminates priority targets.

Tanky (multiple fighters/tanks): Killing Spree. Extended fights require HP recovery to outlast enemies.

Team Synergy

No frontline: Killing Spree. You'll frequently drop below 30% HP—HP recovery compensates for lack of protection.

Strong initiation/CC: Master Assassin. Teammates isolate targets; your +7% secures kills during CC windows.

Map Objectives

Lord/Turtle fights: Killing Spree. Confined spaces create chaotic engagements favoring HP recovery + movement speed.

Split-pushing/side-lane pressure: Master Assassin. 1v1 engagements in isolated lanes favor consistent damage.

Counter-Picking

vs Mobile assassins (Lancelot, Fanny): Killing Spree. Movement speed matches mobility; HP recovery survives burst.

vs Immobile mages/marksmen: Master Assassin. Targets rarely have nearby teammates—guaranteed isolation.

Common Mistakes

Myth: Killing Spree Always Outscales

March 19 buff created this perception. Reality: Master Assassin remains superior for heroes creating consistent isolation. Both achieve similar win rates when properly matched.

One-Size-Fits-All Builds Fail

Copying pro builds without understanding context leads to mismatches. Sun uses Tenacity/Seasoned Hunter/Concussive Blast (not Assassin talents). Badang uses Assassin Emblem despite being a fighter. Analyze your hero's specific needs.

Overlooked Baseline Stats

+16 Adaptive Penetration at max level provides substantial damage. +3% Movement Speed improves rotations regardless of talent. Don't ignore foundation stats.

Point Distribution Errors

Don't spread fragments across multiple emblems. Max level 60 requires 22,773 fragments—focus one emblem first. Ensure Tier 3 unlocks at level 12 for Killing Spree access.

Expert Tips

Pro Player Preferences

Tournament Hayabusa: Master Assassin for consistent damage in coordinated play.

Solo Queue Ling: Killing Spree for chaotic teamfights and snowball potential.

Tournament Meta (Patch 1.9.32)

~60% use Master Assassin (early-game strategies), ~40% use Killing Spree (late-game comps). Both competitively viable.

Advanced Techniques

Maintain multiple emblem configs for different heroes/contexts. Pre-match enemy analysis determines optimal selection. Adapt during draft phase.

Rank Climbing

Solo queue: Killing Spree compensates for team coordination deficiencies. Survivability enables carrying through individual outplays.

Duo queue: Master Assassin maximizes coordinated plays. Allies create isolation; you secure eliminations.

Verdict

No universal winner—choose based on hero, playstyle, context.

Final Recommendation

Master Assassin: Burst assassins (Lancelot, Gusion, Benedetta) relying on isolation and quick eliminations.

Killing Spree: Sustained dealers (Ling, Aamon, Karina) participating in extended teamfights.
