A hero in Last War: Survival is a named character recruited via gacha, story missions, or the season pass who leads troop marches, sits in your base for passive buffs, and unlocks specific content like dispatch missions and rally-leader bonuses. Heroes are the single biggest combat power multiplier in the game past base level 15.
Heroes split into three main classes that match the three troop types: Missile (long-range), Tank (frontline), and Air Force (anti-tank / high damage). Each hero has stats that buff their matching troop class — assigning a missile hero to a march of missile troops gives a stacking attack/defense/HP boost; assigning a tank hero to missile troops gives nothing.
A handful of heroes are "support" — they buff economy (gathering speed, dispatch reward, build speed) rather than combat. Support heroes go in the base/dispatch slots, not on march duty. Recognising the difference is the most common new-player mistake: putting a gathering hero on a rally and wondering why the rally loses.
Heroes have skills (active and passive) that unlock as they level. The most-impactful skills are usually the level-3 passive (a permanent stat aura) and the level-5 active (a once-per-march combat ability). Maxing skills is gated by hero shards (duplicate copies of the hero from gacha).
Hero level scales with hero EXP, which is earned passively and from dispatch / story missions. Star promotion (1-star to 10-star) requires duplicate hero shards — pulling the same hero from gacha gives 1 shard per duplicate; reaching 10-star is the late-game meta target and often requires 200+ shards.
Hero gear is a separate progression on top of star promotion — each hero has 6 gear slots that take faction-specific gear pieces (weapon, helmet, armor, etc.), each with its own enchant level. Maxed gear on a 10-star hero is roughly a 4x power multiplier vs the same hero at 5-star with no gear.
The compounding effect is why hero progression is the single biggest gap between F2P and whale accounts. A whale with maxed gear on the top 5 meta heroes can rally with 3-5x the damage of an F2P account with the same troop count.
A march or rally fields three heroes — one of each class, ideally with synergy skills. The current meta favors a missile-lead, tank-secondary, air-force-tertiary build for offensive rallies, with the heroes' active skills chained for the burst damage window in the opening 30 seconds of combat.
Rally captains (the player who starts the rally) get to set the hero formation; alliance members joining the rally contribute troops only, not heroes. This is why R4/R5 officers run the highest-tier rallies — they have the maxed hero formations to anchor the damage.

Hero recruitment runs through three channels. The standard gacha (recruit tokens from daily missions / events) gives common to rare heroes. The advanced gacha (a separate currency, usually purple tokens) gives elite to legendary heroes with a much higher SSR rate. The shop tab sells specific hero shards directly for diamonds or event currency — slower but deterministic.
Free players should funnel free pulls into the advanced gacha during double-rate events, save standard pulls for the daily mission quota, and spend currency in the shop only on the specific 1-2 heroes they're trying to 10-star.
When you scout an enemy base with LW Spy player search, the dashboard returns the player's power level — and a high power-to-base-level ratio is a strong signal that the player has maxed heroes (the only way to push power up without higher base level is hero gear). Use this to flag whales worth shielding against before a rally lands.
Now that you know what hero is, scan the warzone and see it live. LW Spy gives you real-time data on every base.
