The Black Templars Castellan gains attack power and attack skill with each follower, according to the official squad-system announcement. The developer's specific partner example is Trooper Kozlowski and the extra troopers generated as Lasgun improves.
Why this combination has a basis
Kozlowski's Lasgun upgrades bring more Cadian support into the run. The squad announcement explicitly says those additional troopers contribute to the Castellan's damage output. This is a documented synergy, rather than a build guessed from Warhammer tabletop lore.
It does not establish a numerical bonus per follower, maximum squad count or proof that this is the strongest build for every stage. Those claims would need further data.
Put the system to work
- Confirm which champion you control and inspect the trait shown in your build.
- Choose an available Lasgun attack when appropriate.
- Improve the weapon to develop its support pattern.
- Keep collecting resources yourself: followers cannot collect items for you.
Selecting a weapon may bring a follower when the champion's keywords do not permit direct use. That is expected behavior, not an equipment error.
Evolution is another decision
Lasgun plus Gauntlet produces Meltagun in the inspected release table. A weapon evolution and a per-follower trait are related build considerations, but do not assume a particular follower count survives every transformation without checking the current tooltip. The squad guide explains the general rules and a second, close-range Lorai/Bastian example.
