1. Build Overview & Core Concept

The Mosaic Martial Arts Assassin is one of the most powerful and visually impressive builds in Diablo II: Resurrected. By dual-wielding Mosaic claws, you effectively gain a 100% chance not to consume Martial Arts charges when using finishing moves. This lets you maintain:

  • Phoenix Strike – multi-element novas and meteors
  • Claws of Thunder – lightning chain novas across the screen
  • Fists of Fire – fiery explosions and burning
  • Blades of Ice – cold freezes and defensive control

All of these are unleashed through Dragon Talon, the fastest multi-hit finishing move in the game. The result is a character that feels like a permanent elemental storm: every kick releases fire, lightning, and cold damage in all directions.

If you want to see how a fully optimized version of this build can look item-wise, a complete configuration is represented in the Mosaic Martial Arts Assassin Power Gear Package with Merc, which you can also use as a reference layout while following this guide.

Strengths

  • Top-tier clear speed in dense areas and Terror Zones
  • Excellent single-target damage for bosses and Ubers
  • Multi-element damage naturally handles many immunities
  • Extremely fast, fluid, and satisfying gameplay

Weaknesses

  • Relies heavily on obtaining dual Mosaic claws
  • Can be fragile if Fade, resists, or life are neglected
  • Requires some rhythm and positioning to play at maximum potential

2. Skill Allocation – Endgame Setup

This layout assumes a character around level 90+ with access to endgame gear. You can respec into it once you acquire at least one Mosaic claw, and the build fully awakens with two.

Martial Arts (Core Damage)

Skill Points Explanation
Phoenix Strike 20 Main charge skill; provides fire meteors, chain lightning, and chaos ice bolts.
Claws of Thunder 20 Massive lightning damage; chain novas around you and your targets.
Fists of Fire 20 Adds strong fire explosions and burning, great for mixed-element damage.
Blades of Ice 20 Freezes enemies and adds cold novas; an extra defensive layer and damage source.
Dragon Talon 1–5 Primary finisher. One point is enough with +skills; add more if you want extra AR and kicks.
Claw Mastery 1 Prerequisite; boosts AR and damage for claw attacks.
Tiger Strike 1 Prerequisite only for reaching key skills.

Shadow Disciplines (Survival & Utility)

  • 1 Burst of Speed – main buff for mapping; increases attack and run/walk speed.
  • 1 Fade – use in Ubers or dangerous areas; adds resistances and damage reduction.
  • 1 Weapon Block – gives a chance to block while dual-wielding claws; very efficient defense.
  • 1 Cloak of Shadows – blinds enemies and reduces their defense; an incredible safety tool.
  • 1 Mind Blast – stuns and occasionally converts enemies; helps control dangerous packs.
  • 0–10 Shadow Master – optional; a durable summon that tanks and distracts monsters.

Quality-of-Life Tips

  • Put Phoenix Strike and your favorite charge skills on comfortable hotkeys.
  • Bind Dragon Talon to a key you can spam easily while moving.
  • Keep Cloak of Shadows and Mind Blast nearby for panic moments.

3. Stat Allocation

For a million-dollar feeling Assassin that survives endgame content, follow this stat philosophy:

  • Strength: Just enough for gear. Let bonuses from Enigma, Torch, Annihilus, and charms reduce how many hard points you need.
  • Dexterity: Enough to equip your claws comfortably. You don’t need to chase block from a shield.
  • Vitality: Everything else. More life means more mistakes allowed in Ubers and Terror Zones.
  • Energy: None. Mana is covered through gear, leech, and potions.

If you notice you are drinking mana potions constantly while kicking, you can pick up a bit of mana leech or a few small mana/life charms rather than spending stat points in Energy.

4. Key Breakpoints & Gameplay Feel

You don’t need to memorize every frame table to make this build feel amazing. Focus on these practical goals:

Attack Speed (IAS)

  • Use fast bases like Runic Talons or Greater Talons for your Mosaic claws.
  • Use Burst of Speed in maps – it easily pushes your attacks into very smooth breakpoints.
  • Supplement with IAS on gloves and possibly a jewel in helm or armor if you want an ultra-snappy feel.

Faster Cast Rate (FCR)

If you teleport with Enigma, aim for a comfortable mid-range FCR value from items like Arachnid Mesh, rings, or amulet so Teleport doesn’t feel sluggish. You don’t have to min-max caster breakpoints, but you also don’t want painfully slow casting.

Faster Hit Recovery (FHR)

FHR is especially important in high-density content and Ubers. A few small charms with FHR or gear pieces that naturally include it help you recover quickly from hits, keeping your rotation smooth instead of being stuck in recovery animations.

5. Best-in-Slot Gear (Endgame)

The gear list below is how you turn the Mosaic Martial Arts Assassin into a true endgame monster. A configuration like the Mosaic Assassin Power Gear Setup shows how these pieces can be combined in practice.

Weapons – Dual Mosaic (Non-Negotiable)

Dual-wielding Mosaic claws is what makes this build special. You want fast claw bases and, ideally, good staffmods like +3 Phoenix Strike.

For the absolute top-end version, unmade bases with +3 Phoenix Strike are ideal if you want to roll or configure them yourself:

Armor

  • Enigma (Mage Plate) – Best-in-slot. Teleport alone transforms how you farm and reposition. The strength bonus, faster run/walk, and extra life are all perfect for this build.

Helmet

  • Griffon’s Eye (15% Lightning Skill Damage) – Boosts lightning damage and provides -enemy lightning resistance, which heavily amplifies your Claws of Thunder and the lightning portion of Phoenix Strike.

Gloves

  • Dracul’s Grasp (10% Life Leech / +15 Strength) – Life Tap procs, strength, and life leech make these the best all-round gloves for survivability in melee range.
  • Rare or crafted +2 Martial Arts, 20% IAS gloves – excellent offensive alternative if you want to push attack speed and damage even further, especially for non-Uber content.
  • Early on, Magefist or Trang-Oul’s Claws are good stepping stones if you don’t yet have perfect crafted gloves.

Boots

  • Gore Rider (200% Enhanced Damage) – Crushing Blow, Deadly Strike, Open Wounds, and faster run/walk all synergize perfectly with Dragon Talon. Every kick becomes more lethal.

Belt

  • Arachnid Mesh (+120% Enhanced Defense) – +1 all skills and 20% FCR help both your damage and Teleport speed.
  • Defensive alternatives include Verdungo’s Hearty Cord or String of Ears for more damage reduction, if you can handle slightly less FCR.

Amulet & Rings

  • Mara’s Kaleidoscope (+30 All Resist) – +2 all skills with all resists; perfect for a caster-melee hybrid like this Assassin.
  • Raven Frost (+20 Dexterity) – Cannot Be Frozen, AR, and dexterity; almost mandatory for comfort.
  • Bul-Kathos’ Wedding Band or Stone of Jordan – extra skills and sustain to round out your build.

Charms

  • 8x Assassin Martial Arts Skill Grand Charms – core damage scaling for your charges.
  • Assassin Hellfire Torch (17–19 All Res / 17–19 Stats) and Annihilus – core late-game staples for attributes, skills, and resists.
  • Perfect -70% Lightning Sunder Charm – removes or reduces problematic lightning immunities when combined with Conviction.
  • Additional small charms with life, resistances, FHR, and maybe a bit of AR or mana as needed to smooth out survivability and resources.

Weapon Switch

  • Call to Arms (Flail or Crystal Sword) – +6 Battle Orders – pre-buff life, mana, and survivability.
  • Spirit Monarch (25–29% FCR) – extra skills and FCR to make buffing and teleporting smoother.

Mercenary (Act II)

A strong mercenary massively amplifies your damage and helps keep enemies under control.

  • Aura: Holy Freeze (safety) or Might (more damage).
  • Weapon: Infinity – Ethereal elite base (GT, Thresher, Great Poleaxe, Cryptic Axe, Colossus Voulge). Conviction aura greatly increases your elemental damage and helps break immunities.
  • Armor: Fortitude – Ethereal Archon Plate or Sacred Armor; adds survivability and damage for your merc.
  • Helm: Andariel’s Visage – preferably Ethereal; life leech and IAS. Socket with a Ral rune or resist jewel to fix its fire penalty.

6. Gameplay, Rotation & Farming Routes

Buffs & Preparation

  • For mapping and general farming, cast Burst of Speed.
  • For Ubers or very dangerous content, switch to Fade for resists and damage reduction.
  • Use Cloak of Shadows before engaging big packs to blind enemies and lower their chance to hit you.

Core Rotation

  1. Approach a pack under Cloak of Shadows.
  2. Charge up using Phoenix Strike and its synergies (Claws of Thunder, Fists of Fire, Blades of Ice).
  3. Once you see your charge orbs light up, switch to Dragon Talon.
  4. Spam Dragon Talon at close range: this releases a constant wave of elemental novas, shredding the entire screen.
  5. Stay active: as long as you keep attacking periodically, your charges remain thanks to dual Mosaic.
  6. Refresh Cloak of Shadows and Mind Blast as needed to keep control in dangerous rooms.

Once you are comfortable, the build feels almost like a single flowing skill: charge–kick–charge–kick in a smooth loop while the whole screen detonates in fire, lightning, and ice.

Recommended Farming Areas

  • Chaos Sanctuary – dense, lucrative, perfect for AoE.
  • Cow Level – huge packs that melt to your elemental novas.
  • Terror Zones – most of them are excellent with this build due to multi-element damage.
  • Baal Waves & Throne of Destruction – good for XP and drops.
  • Travincal – strong for runes and gold, especially with solid resists and positioning.

If you prefer following a fully planned endgame item layout while farming, the Mosaic Assassin Gear Package represents a complete reference configuration you can mirror or adapt.

7. Uber Tristram & Boss Strategy

Preparation for Ubers

  • Switch to Fade for extra resistances and physical damage reduction.
  • Stack your resists high, especially lightning and fire, accounting for Uber Mephisto’s Conviction aura.
  • Consider a Life Tap wand on swap for a safety layer in emergencies.
  • Ensure your mercenary is well geared; Infinity and Fortitude help a lot here.

Uber Fight Flow

  1. Pre-buff Fade, Battle Orders (if using Call to Arms), and any other buff you rely on.
  2. Pull bosses one by one when possible, especially Uber Mephisto first.
  3. Cast Cloak of Shadows to reduce enemy defense and limit incoming ranged attacks.
  4. Charge up Phoenix Strike and synergies, then unleash Dragon Talon at close range.
  5. Maintain Life Tap as needed and reposition if you get surrounded or lose your merc.

With dual Mosaic, strong gear, and proper buffs, Uber fights become controlled and relatively quick instead of chaotic and risky.

8. Budget & Progression Path

You don’t need to start with a perfect setup. Here’s a clear path from early game to the full Mosaic Martial Arts Assassin.

Stage 1 – Early Ladder / Fresh Character

  • Level using traps, basic Martial Arts, or a melee hybrid.
  • Use cheap runewords like Stealth and Lore for early power.
  • Any rare or magic claws with +skills and IAS are useful until you get Mosaic.

Stage 2 – First Mosaic & Hybrid Play

  • Once you get your first Mosaic claw, you can start playing a partial Martial Arts build and feel a big power spike.
  • Focus on resistances, life, and attack speed to keep combat smooth.
  • Keep farming high-density areas for runes and gear upgrades.

Stage 3 – Dual Mosaic & Full Power

  • Transition into dual Mosaic as soon as possible – this is where the build truly becomes “permanent elemental storm”.
  • Upgrade into Enigma for teleport mobility and a more fluid farming experience.
  • Optimize your mercenary with Infinity, Fortitude, and Andariel’s Visage.

If you like seeing how fully synergized endgame setups are structured for Assassins, you can look at configurations collected in the Assassin Gear Packages section as reference points while you build toward your ideal Mosaic Martial Arts Assassin.

9. FAQ – Mosaic Martial Arts Assassin

Is dual Mosaic mandatory?

You can technically play with one Mosaic, but the build is designed around dual Mosaic. Two claws give you effectively 100% charge retention, which is what makes the permanent elemental storm playstyle possible.

Which base is better: Runic Talons or Greater Talons?

Both are excellent fast claw bases. Runic Talons are slightly faster; Greater Talons offer strong damage. In practice, either works very well as long as the base is fast and your overall attack speed setup feels smooth.

Is the build good for Ubers?

Yes. With Fade active, solid resists, high life, and strong physical + elemental damage, the Mosaic Martial Arts Assassin is a very capable Uber killer. Just respect mechanics, keep Life Tap handy, and control the fights with Cloak of Shadows and careful pulls.

Can I play this on a budget?

You can start on a budget using generic claws and simple runewords, then gradually work your way into one Mosaic, then two. The build improves dramatically with each gear milestone, and feels “complete” once dual Mosaic, Enigma, and a good merc setup are in place.

What if I want a fully planned reference setup?

Some players prefer following a complete layout instead of piecing together items one by one. In that case, a configuration like the Full dual Mosaic gear package with mercenary can serve as a practical reference for synergy between weapons, armor, charms, and mercenary gear.
