Squad Builder

Tell us your season, the heroes you own and how built they are, and what you're doing — and get the best squad from your roster, plus the meta-ideal comp and what to invest in.

A curated meta recommender (data: Season 6: Lost Rainforest, updated 2026-06-26), weighted by your investment — not a combat simulator. There are no public damage formulas, so treat it as expert guidance, not an exact calculation. Tier ratings reflect the current (Season 6) meta and are broadly season-stable for the UR roster. Per-season availability is gated; per-season historical ratings are not modelled.

Squad setups researched from community guides (lastwarvault.com, lastwarhandbook, packsify, allclash, ldshop, lootbar, lastwargame.online, theriagames) + player ground-truth, and built on the confirmed Season 6 mechanics: pure mono-type gives the same-type bonus (S6 removed the 4+1 hybrid), the type triangle (Tank>Missile, Missile>Aircraft, Aircraft>Tank), and amplifiers (Marshall, Morrison, Sarah, Mason) that multiply the whole squad. Confidence reflects how well each recommendation follows these mechanics and sources — not merely whether a named comp is published.

1. Your season

You own what you own, so your whole roster stays available — the season only controls Awakening. Awakening (Season 6) is hidden for this season. Ratings reflect the current Season 6: Lost Rainforest meta.

2. What are you doing?

Open-field / world-map PvP, single-squad Arena and base fights. Your strongest mono-type squad wins most exchanges.

Drone skill chips — ★ per chip, per troop type (they buff matching-type squads)

Tank

Lethal Firestorm (the Attack chip) is your drone's damage driver, so the builder favours the type whose Lethal Firestorm ★ is highest and flags the weakest to level. For PvP it also counts Gravitational Resonance Armor + Memory Ultra Fission.

Troop Centers — building level per troop type (each boosts its arm's hero HP / Attack / Defense)

Tank Center—
Aircraft Center—
Missile Center—

Level cap follows the season (Seasons 1–2 cap at 30, Seasons 3+ at 35). Whichever Center you've pushed highest makes that troop type relatively stronger, so the builder tilts toward it — enter all three so it's balanced correctly. At level 20 each Center also unlocks its type's Wall of Honor.

3. Your recommended squad

Mark the heroes you own below to get a recommendation.

To improve

  • Meta ideal for PvP / Arena (Open-field) is PvP (Open-field) — Aircraft mono — you're missing Carlie, Lucius, DVA, Morrison, Schuyler.
  • You've marked fewer than 5 heroes owned — add the rest of your roster for a complete squad.

Researched meta setup: PvP (Open-field) — Aircraft monoHigh confidence

Open-field PvP best is Aircraft mono — it counters the common Tank squads and keeps the +20% same-type bonus. DVA carries, Morrison shreds defence, Schuyler stuns. Tank mono is the easier F2P alternative. Source: packsify, lastwarvault, lootbar.

UR gear — what to build

Data ChipCrit Rate + Crit Damage
Reactive ArmorPhysical Defense
RadarEnergy/skill Defense (+crit-dmg reduction at Mythic)
AttackRailgun → Chip → Radar → Armor
DefenseArmor → Radar → Railgun → Chip
SupportRadar → Armor → Railgun → Chip

Railgun = raw attack (DPS first); Data Chip = crit; Reactive Armor = physical defence (tanks first); Radar = energy/skill defence + crit-damage reduction at Mythic (valuable on everyone). Level a piece to 40 before starring; the 5th star = Mythic. Mythic the Railgun + Radar first. Gear is per-hero (20 pieces for a 5-hero squad). Source: lastwarvault, packsify, lastwargame.online.

4. Your roster 0 owned

Tick who you own and set their stars and exclusive weapon level — that's enough for a good ranking. Hit Details on any hero to set each of the 4 UR gear pieces (level, ★ and Mythic) and the 4 skill levels for a sharper result.

5. Tech Center research — enter your levels so the builder reflects your account

Enter the level of each combat research node. This nudges the recommended troop type toward what you've actually invested in, and personalises the “research next” picks on each squad. Your levels are saved to your account and sync across devices (same as your roster), and are shared with the Research Calculator. Economy/growth research doesn't change a squad, so enter that in the Research Calculator.

Aircraft0%

Type-specific research (Mastery + per-arm Hero nodes) by troop type — this is what tilts the recommended type. Universal research (Units, Special Forces, Squad) buffs every type equally.
