How to Build a Necromus Army for Palworld 1.0's Final Boss

The Zenara & Astralym final boss has 420,000 HP and no elemental weakness. Fighting it "properly" is a 15-minute mechanical grind. Fighting it with five awakened Necromus is a 60-second wipe — the Twin Spears skill deals 6,000-8,000 damage per hit, and five Legendary-tier Dark attackers charging together shreds the health pool before the fight has time to happen.

This guide covers the full army build: where to catch Necromus, the same-species breeding lock, which passives actually matter, and how to Awaken the finished squad before the final boss fight.

The plan at a glance

  1. Catch two wild Necromus (needed for breeding — cross-species doesn't work)
  2. Breed same-species pairs, chasing four target passives
  3. Level the finished squad to 80
  4. Awaken with Radiant Gems from the World Tree
  5. Slot all five into your active party and enter Zenara & Astralym

Full workflow below.

Step 1 — Catch your first Necromus

Location: Deep Sand Dunes area, coordinates (446, 681), northeastern Dessicated Desert. The Solitary Necromus spawn is a fixed encounter — it appears there reliably, not as a random world roam.

Level: 60 in the wild. You can be a few levels below and still win the fight; you cannot be more than a few above without accidentally killing it.

The solo strategy — fight at night

Necromus is normally paired with Paladius in a legendary duo, but there's a trick: Necromus is nocturnal, Paladius is not. Approach the spawn at night. Paladius will be asleep, letting you fight Necromus one-on-one instead of the full duo.

This is a huge difficulty reduction. Do not try this during the day unless you have a full endgame team ready to handle both.

Sphere requirements

Bring Legendary Pal Spheres. Necromus has a base Alpha 0.7x capture multiplier, which means even Ultra Spheres at low HP have unreliable catch rates. Legendary Spheres are the only tier that reliably lands the capture — bring 5-8 of them.

Combat approach

Necromus is a Dark-type, so:

  • Weakness: Dragon-type attacks
  • Weapon: high-DPS ranged (Assault Rifle, Grenade Launcher for burst)
  • Team: Dragon-type combat Pals like Jetragon or Astegon
  • Focus the head for weakpoint multiplier

Whittle to critical HP, then throw Legendary Spheres until one sticks.

Step 2 — Catch (or breed) your second Necromus

You need at least two Necromus to start breeding, because the same-species lock (see next step) means cross-species combos won't produce Necromus offspring.

The fastest path: revisit the (446, 681) spawn after the world resets and catch again. Legendary boss spawns respawn on a rolling timer, typically after a few in-game days or after fast-traveling far away and returning.

If you prefer breeding immediately, you can start with your first Necromus and a wild-caught partner of the same species from a repeat spawn — no cross-species Necromus combination exists.

Step 3 — Passives to breed for

Since Necromus can only breed with another Necromus, your breeding pool is limited. The good news: several of the game's best passives are natively rollable on Necromus.

The four passives that matter for the boss fight

  • Legend — +20% Attack, +20% Defense, +15% Move Speed. The single most valuable passive in the game. Roll for this on every child.
  • Demon God — +30% Attack, +5% Defense. Only appears naturally on six Legendary Pals in the game, including Necromus. Highest pure-damage passive.
  • Ferocious — +20% Attack, zero drawback. Clean stackable damage.
  • Swift — +30% Move Speed. Combined with Legend's +15% you hit +45% total, which is enough to reposition mid-fight during Zenara's laser grid phase.

Target roll for each Necromus: Legend + Demon God + Ferocious + Swift. All four is a rare roll — expect to breed dozens of eggs before landing it on all five squad members.

What you CAN'T breed onto Necromus

Same-species Legendary breeding has restrictions:

  • Lucky cannot be inherited (Necromus is not eligible)
  • Earth Emperor cannot be inherited
  • Element-matched exclusive passives from other Pals won't cross over

Don't waste breeding cycles chasing these — they're mathematically not possible via Necromus-only breeding pairs.

Step 4 — The breeding grind

Standard Palworld breeding process:

  1. Assign both parent Necromus to a Breeding Farm with Cake in the storage
  2. Wait for the egg to appear (usually 30-60 minutes real-time depending on Cake availability)
  3. Place the egg in an Incubator — Necromus eggs are Huge Dark Eggs, requiring a large incubator with the right temperature (cool-side setting)
  4. Wait through the incubation timer (~90 minutes real-time)
  5. Check the passives on the hatched Necromus — keep the ones with any target passives, release the rest back into the breeding pool

Expected cycle count: 15-30 hatches to build a full 5-Necromus squad with 3-4 target passives each. Fewer if you use Genetic Recombination to combine partial rolls, which is the intended endgame breeding workflow in 1.0.

Tip: You don't need all four passives on every Necromus. A squad of five with Legend + Demon God + one other is enough to melt Zenara in under two minutes. Chase perfection only if you're chasing perfection for its own sake.

Step 5 — Awakening at Level 80

Once your five Necromus are hatched with acceptable passives, level them to the new Level 80 cap (they cannot exceed your own player level, so cap yourself first).

Then Awaken each one using Awakening Crystals — the new 1.0 progression system that boosts stats significantly. Each Awakening Crystal takes 50 Dark Radiant Gems + 10 World Tree Holy Water at the Ancient Workbench. Radiant Gems drop from element-matched Pals inside the World Tree biome. For the full farming route, per-element gem locations, and how to skip the node-shatter mechanic, see World Tree Resource Farming.

Prioritize Awakening in this order:

  1. The Necromus with the best passives (usually Legend + Demon God + something)
  2. The next two with the best rolls
  3. The last two — even without Awakening, they still contribute Twin Spears damage

If you're short on Radiant Gems, three Awakened + two base is still enough to clear the fight.

Step 6 — Team assembly and verification

Slot all five Necromus into your active party. That's your entire team for the Zenara & Astralym fight — no need for a support Pal since the strategy is pure burst damage.

Verify the build before the boss run:

  • Fight any Alpha boss in the Sunreach or Feybreak regions to test your Necromus DPS
  • If Twin Spears hits are landing in the 6,000-8,000 range consistently, you're ready
  • If hits are below 4,000, you probably need better passives, more Awakening, or higher player level

Executing the cheese

Once inside the Zenara & Astralym arena:

  1. Survive phase 1 (the wing charge is still a one-shot risk — don't ignore it)
  2. Deploy all five Necromus as soon as combat starts
  3. Trigger Twin Spears manually with the active skill button — don't rely on auto-cast alone
  4. Stay behind them — Necromus takes hits and you shouldn't. Use them as a wall while triggering skills
  5. Total fight time: ~60 seconds of active DPS assuming all skills hit

The 420,000 HP pool typically drops in under 90 seconds with a properly-built Necromus squad, well before phase 3 self-destruct becomes a concern.

Is this "cheating"?

Mechanically, no — this uses only in-game systems (base capture, standard breeding, official passives, Awakening with Radiant Gems). It's the intended endgame use for Legendary Pals: build a specialist team, apply it to the hardest content, feel powerful.

If you want the intended experience with mechanic-check gameplay, use the full walkthrough instead. If you've spent 30+ hours grinding a Legendary squad and want the payoff — this is that payoff.
