The Best Last War Season 1 Week 6 Guide: Tesla Exclusive Weapon Levels, Inductive Current, and Full Missile Squad Strategy

Tesla's Exclusive Weapon is not just a stat stick. Its real value comes from the way each breakpoint adds a new layer to his damage pattern. Early levels improve his single-target pressure, Level 10 unlocks the massive back-row wipe that makes him scary in PvP, Level 20 rewards proper Missile-team building, and Level 30 ties everything together with extra damage scaling.

That means Week 6 is not simply about unlocking the weapon and forgetting it. It is about identifying the milestone that gives you the biggest immediate power jump, then building the right squad around Tesla so the later upgrades actually reach their full ceiling.

At Level 1, Tesla's Exclusive Weapon unlocks its first real combat effect alongside the base stat boosts. This is where the weapon starts defining Tesla's identity as an Energy Damage hero built around stacking pressure rather than simple burst alone.

The unlocked skill is Lightning Chain II. It hits 1 enemy unit and deals Energy Damage equal to 408.11% of Attack on a 1.35-second cooldown, while also applying 1 stack of Inductive Current. Even though this is only the starting breakpoint, it lays the groundwork for everything the weapon does later.

In practice, Lightning Chain II is a strong starter skill because it begins the stacking loop early and keeps pressure on enemy lines. It may not be the most dramatic unlock in the tree, but it is the foundation that makes the higher-level weapon effects much more threatening.

Level 10 is the breakpoint that turns Tesla into a real battlefield problem. It also raises Tesla's core skill max level cap to 33, but the bigger story is the unlocked weapon skill itself: Electric Grid Lockdown II.

Electric Grid Lockdown II hits 3 back-row enemy units and deals a massive 1182.52% Energy Damage based on Attack on a 10-second cooldown. It also applies 2 stacks of Inductive Current. That combination of target pattern, damage, and stack application is exactly why so many players treat Level 10 as the non-negotiable Tesla milestone.

The tactical value here is enormous. Back-row enemy units are usually the squishier, high-damage dealers in PvP lineups, so a nearly 1200% attack multiplier aimed directly at that row can completely swing a fight. If you are deciding where to stop early investment, Level 10 is the strongest answer by far.

At Level 20, Tesla's core skill level cap rises again to 36 and the weapon begins buffing your entire squad, provided you are building around the correct troop type. This is the first point where the weapon stops being only a Tesla upgrade and starts acting like a team-wide amplifier.

The unlocked skill is [Troop Type Boost] Missile Specialist. It boosts all Missile Vehicle heroes' Attack, Defense, and HP by 7.50% in battles. That last phrase matters more than many players expect.

Because the buff applies dynamically only when battle starts, you will not see an immediate jump in total Squad Power on your Garage screen after reaching Level 20. That often confuses players into thinking something is broken or underwhelming. It is not. The stats are real, but they appear only in actual combat against zombies or other players.

Level 30 pushes Tesla's core skills to a max level of 40 and unlocks the final tactical piece that makes his entire weapon tree feel complete. This is the point where Tesla's stacking mechanic becomes a direct damage multiplier instead of just a background debuff engine.

The unlocked skill is [Tactics Boost] EM Induction. Tesla's auto-attacks add an extra stack of Inductive Current to a random enemy back-row unit, and Tesla deals 1% more damage for each stack of Inductive Current on the target, up to a cap of 15% bonus damage.

This skill has perfect synergy with Level 10's Electric Grid Lockdown II. By automatically adding stacks to the enemy back row, Tesla softens up exactly the units he most wants to delete. When the AoE nuke lands, it is hitting targets that are already primed for bonus damage, which is why Level 30 feels so oppressive in properly built Missile teams.

Throughout Tesla's weapon progression, the most important recurring mechanic is Inductive Current. In some versions of the Exclusive Weapon screen, clicking the orange underlined term may fail to show its details because of UI issues, so it helps to know exactly what it does from Tesla's hero page.

Inductive Current deals continuous Energy Damage equal to 3% of Tesla's Attack per second and lasts for 30 seconds. The stacking rule is the real key: the maximum number of stacks an enemy can hold is equal to the number of Missile Vehicle heroes in Tesla's squad multiplied by 3.

That rule completely changes how you should build around Tesla. If you want to maximize Level 30's EM Induction bonus, you should run him in a full Missile hero squad. The math is simple: 5 Missile heroes multiplied by 3 stacks each gives you a 15-stack ceiling, which matches the full 15% bonus damage cap. If you mix in Aircraft or Tank heroes, you lower the maximum possible stack count and directly reduce Tesla's final damage output.

If you want the practical version of this entire guide, it comes down to three decisions. First, rush Level 10 because Electric Grid Lockdown II is too strong to delay if Tesla is part of your real combat plans. Second, do not get tricked by the Garage screen at Level 20 because Missile Specialist is a battle-only stat buff. Third, commit to a full Missile squad if you want Level 30 Tesla to hit his real ceiling.

Tesla's Exclusive Weapon is one of the clearest examples in Season 1 of a hero system that rewards both investment and understanding. If you build around it correctly, Tesla becomes a terrifying back-row killer with real scaling into later weapon levels.

More Season 1 guides can continue from here with DVA and Carlie weapon upgrades, but if Tesla is your current priority, this is the progression path that gives the biggest payoff.
