Grey Knights: Grand Master In Nemesis Dreadknight

The Grey Knights Grand Master in Nemesis Dreadknight is a towering centerpiece for Grey Knights armies, combining the elite tactical leadership of a Grand Master with the devastating firepower of a heavy war suit. 

The Model & Customization
This multipart plastic kit consists of 125 components and can alternatively be built as a standard Nemesis Dreadknight. It features a significant upgrade sprue that adds distinctive elements to distinguish the Grand Master from a regular pilot: 

Visual Distinctions: The Grand Master variant includes a different pilot harness, unique knee pads, and ornate cosmetic additions such as a tilting shield and an open book that sits atop the frame.
Assembly: The model is poseable, and ranged weapons can be mounted on either arm. It is supplied with a 120mm by 92mm oval base.
Heads: The kit provides choices between a bare head or a specialized helmet for the pilot.

Wargear Options
The Grand Master has access to a wide array of high-caliber weaponry, often comparable to battle-tank ordnance. 

Melee Weapons:
Nemesis Daemon Greathammer: Highly effective against heavy targets.
Nemesis Greatsword: Offers a "sweep" attack for clearing hordes or a "strike" for single targets.

New Upgrades: The 2025 release introduced the Nemesis Mace and Nemesis Flail.
Ranged Weapons:
Heavy Psycannon & Gatling Psilencer: Standard heavy firepower options.
Heavy Incinerator: A powerful flame weapon.
Specialized Upgrades: Includes the Sublimator (a powerful melta-style weapon) and the Fragstorm Grenade Launcher. 

Battlefield Role
In current gameplay, the Grand Master variant acts as a specialized damage dealer: 

Anti-Armor Specialist: Its Surge of Wrath ability allows it to reroll Hit, Wound, and Damage rolls when targeting Monsters or Vehicles, making it exceptionally efficient at "deleting" heavy targets.
Utility: The Warrior Strategist ability allows you to reduce the CP cost of a Stratagem targeting this unit once per battle round.
Survivability: It typically possesses a 4+ invulnerable save and remains a formidable threat even as it takes damage.
