Last War Season 1 Hero Level Swap Guide

In Last War Season 1, the Level Swap feature allows you to exchange the level values of two heroes instantly. To perform a swap, open the Season 1 event interface, select the high-level hero whose experience you want to reallocate, and select the target hero who will receive that level. The exchange takes effect immediately without requiring Hero EXP books or a standard character reset.

How Level Swap Works

Level Swap trades the exact base level numbers between the two selected heroes. The higher-level unit drops to the level of the lower-level unit, and the recipient hero immediately jumps to the higher level.

This exchange directly affects level-dependent statistics:

Troop Capacity: Scales immediately to match the newly assigned level.
Base Attributes: Attack, Defense, and HP adjust to the new level value.
Squad Power: The drill ground power and march combat rating update to reflect the new base stats.

Level Swap does not transfer all progression elements. Only raw experience levels move between heroes.

Hero Progression Element	Transferred in Swap?	Result
Base Hero Level	Yes	Directly exchanged between both units.
Troop Capacity	Yes	Recalculated according to the new level.
Base Stats (HP, ATK, DEF)	Yes	Adjusted to match the new level tier.
Skill Levels	No	Remains on the original hero.
Star Rating	No	Stays tied to consumed hero shards.
Equipment & Exclusive Gear	No	Remains equipped to the original hero.

When to Use Hero Level Swap

Because leveling a hero from level 1 requires significant Hero EXP and gold, Level Swap serves as a shortcut for major squad transitions:

Pivoting Squad Types: If you invested early resources into a full tank squad using heroes like Murphy, Mason, or Violet, you can transfer those levels into aircraft units such as DVA, Carlie, or Schuyler once your aircraft tech is ready.
Deploying Newly Acquired UR Heroes: Late-acquired UR heroes often sit idle due to lack of EXP. A swap brings them directly to your main squad's level tier.
Building Counter Formations: If opposing alliances run heavy tank squads, you can rapidly promote missile or specialized counter units to field a competitive march without draining your account's broader economy.

Pitfalls to Avoid Before Swapping

Swapping base levels into an undeveloped unit does not guarantee a combat-ready march. Avoid these common mistakes:

Neglecting Star Ratings: A high-level hero with zero stars often underperforms compared to a lower-level hero with 5 stars. Do not swap your main carry's level to a replacement hero unless their star tier can support competitive combat.
Ignoring Skill Levels: Level Swap does not move skill points. If your recipient hero has level 1 skills, their damage output and utility will drop sharply. Prepare skill medals to level their abilities before sending them into Warzone Duel or Capital Clash.
Missing Equipment: Gear does not automatically transfer during a level swap. Ensure you have appropriate legendary gear (gun, armor, radar, and chip) ready for the recipient hero to prevent a sudden drop in squad effectiveness.

Best Timing for a Swap

Execute your level swaps during quiet periods rather than during active PvP defense or kill events. Changing levels mid-battle can leave your defensive wall lineup weakened while you rearrange gear and squad formations. Plan swaps ahead of Alliance VS hero development days or right after a Warzone Duel round concludes, giving you time to equip gear, upgrade skills, and set your defensive march presets.
