Mosaic

Mosaic is a game-changing Assassin runeword introduced in Diablo 2 Resurrected Patch 2.4 that revolutionized Martial Arts builds. Created with Mal + Gul + Amn in 3-socket assassin claws, this runeword enables permanent charge-up skill uptime through its revolutionary charge preservation mechanic.

The Charge Revolution

Mosaic's defining feature is +50% Chance for Finishing Moves to Not Consume Charges. When dual-wielding two Mosaic claws, this stacks to 100% chance, meaning finishing moves like Dragon Talon never consume your built-up charges from skills like Phoenix Strike, Claws of Thunder, Fists of Fire, and Blades of Ice. Additionally, each finisher refreshes the 15-second charge expiration timer, allowing permanent uptime on all six charge-up skills simultaneously.

Build-Defining Mechanics

The Mosaic Assassin charges all desired skills once, then spams Dragon Talon to unleash waves of elemental destruction without recharging. This creates a "Christmas tree" effect where meteors, lightning novas, ice shards, and fire explosions trigger with every kick. The build deals four damage types simultaneously, trivializing immunities across Hell difficulty and Terror Zones.

Core Stats and Synergies

Beyond charge preservation, Mosaic provides +2 to Martial Arts, +20% Increased Attack Speed, +200-250% Enhanced Damage, 7% Life Steal, and +8-15% to Cold/Lightning/Fire Skill Damage. The Prevent Monster Heal aids boss killing. While the base stats appear modest, the charge preservation mechanic makes Mosaic irreplaceable for Martial Arts builds.

Optimal Claw Selection

Critical Staff Mods

Since Mosaic requires two claws, the staff mods become crucial. Ideal claws feature:

• +3 Phoenix Strike or +3 Claws of Thunder - Maximize elemental damage output
• Greater Talons - Slightly superior base but any claw works if the skills are correct
• Additional +skills to charge-up abilities compound damage significantly

Endgame Dominance

The Mosaic Assassin excels everywhere: general farming, Terror Zones, and even Ubers with minor adjustments. Supporting gear includes Chains of Honor or Treachery for defense, Dracul's Grasp for life tap sustain, and Griffon's Eye or rare circlets for additional skills. The build's only weakness is needing to refresh charges every 14 seconds, requiring consistent enemy contact.

Value

The Gul and Mal runes are moderately expensive but achievable through Hell Countess, Travincal, and Lower Kurast farming. Finding properly skilled claws is often harder than acquiring the runes. For Martial Arts Assassins, Mosaic isn't just best-in-slot—it's the difference between a functional build and an S-tier powerhouse that redefined the class.
