Trooper Kozlowski: Holding the Line with the Astra Militarum
While Space Marines like Malum Caedo rely on ceramite plating to absorb enemy hits, the Astra Militarum's Trooper Kozlowski relies on discipline, superior firing speed, and agile footwork. Armed with standard-issue flak armor and an Imperial Lasgun, Kozlowski turns the humble guardsman into an agile marksman capable of wiping late-game hordes.
For an evaluation of how Kozlowski stacks up against the wider roster, see our Champions Tier List and master Evolution Recipes List.
The Marksman Sniper Build
Kozlowski's innate trait Take Aim! adds +20% projectile speed and +1 pierce to every ballistic weapon. This makes straight-firing weapons hit twice as many targets per shot.
1. Weapon Progression
- Lasgun $\rightarrow$ Meltagun (Primary): Maximize the Lasgun first. Kozlowski's projectile speed bonus makes the thermal beam register instant hits across the screen. Detailed in our Lasgun Evolution Guide.
- Boltgun $\rightarrow$ Heavy Bolter (Knockback): Adds heavy concussive rounds to keep enemies at bay. Read the Boltgun Evolution Guide.
- Chainsword $\rightarrow$ Eviscerator Chainsword (Melee Safety): Essential close-quarters safety ring when kiting around obstacles. Read the Chainsword Evolution Guide.
- Frag Grenades $\rightarrow$ Vortex Grenades (Cluster Trap): Throw explosives behind you as you lead swarms through narrow corridors.
- Whirlwind Battery $\rightarrow$ Orbital Bombardment: Softens up incoming hordes before they enter visual range.
- Boltstorm Pistol $\rightarrow$ Typhoon Crossbow: High-speed bouncing bolts benefit heavily from Kozlowski's native pierce.
2. Core Passive Relics
- Gauntlet (Mandatory): Evolution key for the Lasgun; adds flat armor that prevents Kozlowski from getting one-shot.
- Dice Cube (Mandatory): Evolution key for the Boltgun; expands global critical strike chance. Read our Dice Cube & Passives Guide.
- Sabaton: Increases movement speed, ensuring Kozlowski maintains distance from sprinting Genestealers.
- Tape Measure: Widens grenade detonation zones and melee security swings.
- Nuln Oil: Grants cooldown reduction and additional movement velocity.
- White Dwarf: Magnet radius expansion to collect XP gems without backtracking into dangerous crowds.
Step-by-Step Kiting Strategy
| Minute Interval | Tactical Priority |
|---|---|
| 00:00 – 04:00 | Walk in broad, continuous clockwise circles. Fire your Lasgun into the densest clusters. |
| 05:00 | Slay the first elite mini-boss and collect the Golden Chest to claim the Meltagun. |
| 05:00 – 10:00 | Draft secondary AoE tools (Boltgun, Chainsword) to prevent getting swarmed from behind. |
| 10:00 | Face the 10-minute Extremis boss. Use the Meltagun's piercing beam to snipe the boss through minion swarms. |
| 15:00 – 25:00 | Maintain maximum distance. Let your evolved artillery and thermal beams clear the path ahead. |
Conquering Boss Encounters
Kozlowski's high mobility makes him exceptional at dodging boss attacks. When fighting the Norn Emissary Boss, you can comfortably sprint outside the radius of its psychic explosions while keeping the Meltagun trained on its center of mass.
