Last War Drone Guide: Components, Parts and Chip Priority (October 2026)

For Last War: Survival players who want to know how the drone system actually works, which upgrades matter at each stage, and why your first-month component choice is so hard to undo.

The Tactical Drone fights alongside your squad in every battle, on the world map, in PvE and in PvP. Enemies cannot target it. Every level, Component and Skill Chip you add gives a flat stat buff to your whole hero lineup in every fight the account takes part in.

That makes the drone different from almost every other investment. A hero upgrade improves one hero. A gear piece improves one slot. A drone upgrade improves every squad you field, in every battle. Accounts that treat the drone as a background system usually notice the gap around HQ 25, when opponents with the same hero and gear levels start winning fights they should not.

Short answer: open Component Choice Chests on the right side (Missile, Fuel Cell, Thermal Imager), get the Component Factory to Level 19 before Age of Oil and collect it daily, push Combat Boost to Level 10 for the four Skill Chip slots, and craft chips in the order Interference, Defense, Initial Move, Attack.

This guide covers which component side to pick, the Component Factory, the Drone Parts Workshop, how Drone Parts gate late-game levels, Combat Boost, and the 2026 Skill Chip priority.

Drone components: which side to pick

Drone components unlock at HQ Level 15. Six equipment slots open, split into left-side and right-side components. Both sides give stat buffs to the drone and your squad, but the right-side components (Missile, Fuel Cell, Thermal Imager) have higher base stats and better long-term scaling than left-side ones at the same rarity.

The reason it matters: left-side components drop roughly twice as often as right-side ones from random Drone Component Chest rewards. The game already floods you with left-side pieces, so right-side pieces are the scarce ones. Every Component Choice Chest you open should go right-side.

This is not a call based on what you need right now. It is a fixed rule. Players who pick left-side from choice chests because their left slots look lower end up with a lopsided drone that is expensive to fix, because passive drops never give back right-side pieces at a competitive rate.

Component upgrades work in two stages. Up to Level 7, you merge three components of the same level into one at the next level. From Level 8, merging stops and upgrades need Research Value. Every full 1% of research progress raises the component's attributes once, with bonus attribute spikes at 20%, 40%, 60%, 80% and 100%. Progress below 1% does not trigger an increase, so do not split research across several components at once if you want to see gains.

Rule: Component Choice Chests always go right-side. The left side fills itself from passive drops.

Component Factory: what level to target

The Component Factory produces Level 1 Drone Component Chests passively. It unlocks at HQ Level 15 and runs on a continuous cycle. Each upgrade cuts the production time per chest and raises daily output.

It goes up to Level 35, and Levels 31 to 35 need the Age of Oil event and Base Expansion research in the Oil tech tree. For most competitive accounts, the practical target before the Age of Oil gate is Level 19, which produces 7 Level 1 Drone Component Chests a day. That is enough for steady component progress without the building fighting higher-priority structures for your construction queues.

One thing most players miss: the factory stores up to 24 hours of production. Anything past that is lost. Collect it daily.

The factory only makes Level 1 chests. Higher-tier chests come from VS Day performance (Level 3 chests for higher ranks), Radar missions, Secret Tasks and specific event rewards. Those sources are not guaranteed every cycle, so VS Day performance is the most reliable path to higher-tier chests. Maxing the factory does not replace them. It gives you a daily floor of component income so your progress never stalls.

Get the Component Factory to Level 19 before Age of Oil, then push to 35 once the Oil requirements are met.

Drone Parts and the Parts Workshop

Drone Parts are a separate resource from Components, and they gate drone levels past 150. Below Level 150, the drone levels with Battle Data. From Level 150, every level needs Parts, starting at 500 Parts per level and going up by 100 every ten levels. By Level 200, each level costs over 1,000 Parts. By Level 250, costs are high enough that you need to stockpile seriously between events.

A mechanic players miss all the time: while your upgrade bar is below 80% of the next level, Battle Data has a 50% chance to crit and give double experience. Past 80%, crits stop. Stop at 79% and save the rest of your Battle Data for the next session to keep the crit window open.

The Drone Parts Workshop is a separate building from the Component Factory. It unlocks through Age of Oil research at HQ 30 and becomes the main passive source of Drone Parts in the late game, producing Parts daily at a rate that grows with its level. Before HQ 30, Parts mainly come from Alliance Duel VS Drone Development Day rewards, specific event packs and the Alliance Store.

On the Alliance Store: you can buy Drone Parts there, but weigh it against hero shards first. If your hero roster is not finished, hero shards usually give more account-wide power per coin. Once your core squad setup, the main five heroes, is at a competitive level, Drone Parts become the priority buy.

Stockpile Drone Parts between events and spend them on Alliance Duel Drone Development Day for double scoring.

Combat Boost

Combat Boost is the drone's first active combat layer and the requirement for Skill Chips. It activates on server day 85 once Combat Boost Level 10 is reached through the drone tech tree on the Age of Oil research track.

Combat Boost Stages upgrade with Epic Skill Chips as material once those chips leave active slots. That is the main use for Epic chips after Legendary replacements are crafted and equipped. Do not throw them away. Feed them into Combat Boost Stage upgrades.

Order of work: push Combat Boost to Level 10 as fast as you can once the day 85 gate opens. That unlocks all four Skill Chip slots at once. Every day below Level 10 is a day without Skill Chips, which in the Season 6 meta is a real damage disadvantage in VS Kill Day and Desert Storm Battlefield.

Skill Chip priority for 2026

Skill Chips are the biggest single power jump in the drone system and its final layer. Four slots open when Combat Boost reaches Level 10: Initial, Attack, Defense and Interference. Each chip is crafted in the Chip Lab for a specific hero type (Tank, Aircraft or Missile) and must match the hero type of your main formation to give its full effect.

The 2026 order is different from older guides that ranked Attack second:

1. Interference (Memory Ultra Fission): reduces enemy tactic damage. The most impactful chip in the Season 6 meta because it directly counters burst-heavy builds around Kimberly and DVA Awakening. Most servers run Tank-heavy lineups in Season 6, so Interference adds a lot of defensive value in almost every competitive fight.
2. Defense (Gravitational Resonance Armor): a defense buff for the whole battle for the hero type it was crafted for, plus a smaller global buff to the whole squad. Duration is the point: unlike chips that only act in the opening seconds, this one works for the full fight.
3. Initial Move (Absolute Quantum Field): a shield for the opening seconds of battle, strongest on Tank heroes, then reduced incoming damage globally after the shield ends. Strong in VS Kill Day and Capitol Duels, where the first seconds decide whether your formation survives contact.
4. Attack (Drone Strike): raises attack power and drone target count. At star level 5 the target count goes up to 3, which makes it strong against multiple targets, but it does not have the defensive value of the top three in a burst-heavy meta.

Chip Lab target: the Chip Lab goes to Level 35, but every chip can be crafted by Level 20. Levels 21 to 35 are stat polish with steep costs and long build times. Park the Chip Lab at 20 and put your queues into Drill Ground, Tech Center, Barracks or the Drone Parts Workshop.

Star level discipline: keep star levels even across all four chips. When all four are at the same star level, the Resonance set bonus gives a global stat multiplier to the whole squad on top of the chip effects. If one Legendary chip is at star level 2, bring the other three to star level 2 before taking the first to 3. Uneven star levels switch the bonus off until the others catch up.

Epic chips: keep them equipped until Legendary replacements are crafted and ready to swap in. Do not pull Epic chips and leave slots empty while you farm Legendary materials. An equipped Epic gives real buffs every fight. An empty slot gives nothing.

The drone fights in Zombie Siege too, buffing your whole formation every wave. A high-level drone with maxed Components and Legendary chips is especially valuable in the late waves (15 to 20), where Interference and Defense cut incoming pressure.

Alliance leader playbook

Drone progress rewards coordinated alliance discipline more than individual spend. The best R5 call is telling members to save Parts through the week and spend them inside the Alliance Duel Drone Development window. 20 to 30 members each spending 500+ Parts gives a duel score ceiling other alliances cannot match passively. Announce it 48 hours before duel day.

Pin the Component Choice Chest rule in alliance chat: right-side pieces only (Missile, Fuel Cell, Thermal Imager), unless a member runs a tank-heavy rally defense squad. Members who open Choice Chests randomly or default to left-side hold their squads back for the whole season.

Before every major event window (Alliance Duel, SvS, capital siege), check your starters' chip sets. A member with three Legendary chips and one empty slot gets less from the drone than a member with four Epics and an intact Resonance bonus. Most R5s never check.

Two more alliance-level wins. Get members to put Drone Parts Workshop upgrades into their construction queues (180 free Parts a day across 30 members). And once Combat Boost unlocks chip presets, enforce preset discipline: separate setups for rally offense, PvP defense and Zombie Siege. One generic preset for every mode is a large hidden performance loss.
