The Zealot is a versatile class that spends most of there time upfront in the enemies faces, usually alongside the Ogryn, if you have one. This build plays into that aspect of the Zealot class quite well, using the Heavy Sword to quickly dispatch hordes with heavy swings, and is effectively strong against elites. When it comes to Elites/Specials at mid-range, the Heavy Laspistol is unmatched in effectiveness. These weapons together make for an extremely potent combination and build. With this build, you can stay in the front-lines cutting through everything with ease. Let the Veteran/Psyker take out the elites from long distances, and focus on everything that moves nearby.
The Heavy Sword is one of the best weapons the Zealot can use. It’s very strong heavy attacks can cut through hordes with heavy, and it’s attack pattern make its very easy to deal with Elites.
Perfect Strike is helpful to deal with Elites/Specials as it ignore the mass on critical strikes. Headtaker is one perk required for this weapon, you can easily stack power with one swing, increasing your offensive capabilities immensely.
Critical Hit Chance comes recommended as it works well with Perfect Strike, and increases the chances of activating. Maniacs of Flak will give good coverage over enemy types.
The Heavy Laspistol is a very strong, if not the strongest weapon to pair here. Its mid-range damage is nearly unmatched, and easily deals with Elites/Specials that are out of melee range.
Infernus adds a stacking burn effect that deals damage overtime. This is most noticeable when dealing with Monstrosities or Ogryn type enemies. On some of the hardest difficulties, you’ll see this effect coming in handy against all Elites. Dumdum is a stacking damage boost when getting repeated hits on close range enemies. Both these perks together shred through both Elites and Monstrosities alike.
Flak and Maniac modifiers are the highly recommended modifiers for this weapon, as it covers Elites/Specialists of nearly all types.
Curios are really flexible, with only a couple perks that really benefit builds. In this case, Toughness can be substituted for Health if required, but Toughness is still recommended. You will want at least 1 Curio to have 1 Wounds on it, wounds increase the amount of health bars you have. This is beneficial, especially on higher difficulties, as it allows some leeway if mistakes happen, or you get overwhelmed.
Stamina Regen is really important and should be the only modifier you go for one each Curio you use. Block Efficiency is great to have to further extend the capabilities of your melee weapon.
