Drone Combat Boost & Skill Chips โ€” Day 82 Plan

What unlocks on day 82, the squad-specific chip craft order, and how RAV3 turns it into compounding alliance power.

Last updated 4/28/2026

Drone Combat Boost and the Chip Lab both unlock on server day 82, gated only by HQ level 15. Combat Boost is a universal multiplier โ€” it raises the power of your drone AND every chip you slot. The Chip Lab is where you craft those chips. Everything earned in this system is permanent and compounds for the rest of the server.

This is what you log into on day 82: the Combat Boost Starter Mission. 6+ days of tasks that hand you Combat Boost EXP cards and chip materials โ€” the cheapest XP in the system. Do not skip a single task.

What unlocks on day 82

  • Combat Boost โ€” universal multiplier on your drone and every equipped chip. Levels feed permanently.
  • Chip Lab building โ€” craft, fuse, and disintegrate chips. Goes to level 20 to unlock all SSR + UR chips.
  • Four chip slots: Initial Move, Attack, Defense, Interference.
  • Eight chips total โ€” 4 SSR (mid-tier) and 4 UR (endgame).

The 8 chips by slot (in-game slot order)

  • Slot 1 Initial Move โ€” SSR: EM Shield. UR: Absolute Quantum Field. Battle-start shield + post-shield damage reduction (UR).
  • Slot 2 Attack โ€” SSR: Ultra Frequency Resonance. UR: Lethal Firestorm. Damage per drone strike; UR hits more targets.
  • Slot 3 Interference โ€” SSR: Armor-piercing Pulse. UR: Memory Ultra Fission. Damage increase + back-row bonus + enemy tactic reduction (UR).
  • Slot 4 Defense โ€” SSR: Photon Armor. UR: Gravitational Resonance. Team defense buff, with extra for front row (UR).

Day 78โ€“82 โ€” Prepare now (4 days out)

  1. Hoard drone speedups and accelerators. Do NOT spend them on the current drone tree; save for Combat Boost levels.
  2. Stockpile Drone Combat Data โ€” buy from every Arms Race and Daily Sale rotation. Combat Data also drives Arms Race Drone Boost scoring.
  3. Stop opening any Skill Chip chests you already have. Bank them and open in a coordinated window once the Lab is live.
  4. Donate to alliance tech every login โ€” alliance coins fund chip chests in the Alliance Shop later.
  5. Decide YOUR main squad type (Tank / Air / Missile). Chips bind to hero type, so picking before day 82 means you craft cleanly from minute one.

Tank squad โ€” craft order

  1. SSR craft order: EM Shield โ†’ Photon Armor โ†’ Ultra Frequency Resonance โ†’ Armor-piercing Pulse.
  2. SSR 2-star order: same as craft order. Get every SSR to 2 stars before pushing any chip past it.
  3. Only Ultra Frequency Resonance goes to 10 stars among SSRs. Every other SSR sits at 2 stars until you replace it with UR.
  4. UR craft order: Absolute Quantum Field โ†’ Gravitational Resonance โ†’ Lethal Firestorm โ†’ Memory Ultra Fission.
  5. First UR to 5 stars: Lethal Firestorm (the multi-target unlock).

Aircraft / Missile squad โ€” craft order

  1. SSR craft order: EM Shield โ†’ Ultra Frequency Resonance โ†’ Armor-piercing Pulse โ†’ Photon Armor.
  2. SSR 2-star order is different from craft order: Ultra Frequency Resonance โ†’ Armor-piercing Pulse โ†’ EM Shield โ†’ Photon Armor.
  3. Only Ultra Frequency Resonance goes to 10 stars among SSRs. Every other SSR sits at 2 stars.
  4. UR craft order: Lethal Firestorm โ†’ Memory Ultra Fission โ†’ Absolute Quantum Field โ†’ Gravitational Resonance.
  5. First UR to 5 stars: Lethal Firestorm.

Upgrade rules

  • 2-star EVERY chip before pushing any single chip past 2. The 2-star jump is significantly larger than any other level upgrade.
  • Universal star-push order once everything is at 2โ˜…: Lethal Firestorm โ†’ Absolute Quantum Field โ†’ Memory Ultra Fission โ†’ Gravitational Resonance Armor (top โ†’ middle โ†’ left โ†’ right). Same order across all squad types.
  • Disintegrate replaced SSR chips into Combat Boost โ€” that's their permanent value once you upgrade slots to UR. Only SSR-rarity disintegrates into Combat Boost.
  • Star equivalency: an 8-star SSR โ‰ˆ a 3-star UR. A 10-star SSR โ‰ˆ a 4-star UR. Don't over-invest in SSR levels you can't recover.
  • Park the Chip Lab building at level 20 โ€” that unlocks every SSR and UR craft. Levels past 20 are stat polish with brutal scaling; push other buildings instead.

Arms Race โ€” Drone Boost phase (4-hour window)

  1. Save stamina the day before. Stamina spent in combat (zombies, radar, rallies) scores during the phase, so a full bar at phase start is free points.
  2. Save Drone Combat Data too. Inside the phase: Drone Center โ†’ Data Training โ†’ spend 10 Combat Data at a time. Every spend scores AND levels Combat Boost.
  3. Pair the phase with radar missions and alliance rallies โ€” they score under the stamina rule, so you double-dip.
  4. Bring drone parts. Some triggered upgrades consume parts; running out mid-phase leaves points on the table.

Where to farm Combat Data + chip chests

  • Alliance Shop โ€” up to 5 Rare chip chests/week + Combat Data bundles. Daily tech donation funds your coins.
  • Campaign Shop โ€” 1 Epic chip chest/week. Always buy.
  • Honor Shop โ€” 1 Legendary chip chest/month. Always buy, even if you skip other Honor items.
  • Daily zombie kills โ€” drop drone parts and combat data. Never skip the daily quota.
  • VIP Store โ€” extra weekly chests on rotation if you run VIP.

Alliance coordination โ€” what actually compounds

  1. Donate to alliance tech every login. Members short on coins leave chip chests on the shelf.
  2. Bank Skill Chip chests and open them on Monday morning of an Alliance Duel week โ€” Day 1 (Radar Training) is the only VS day they score.
