Dooley
Robot Revolutionary
Dooley builds around a Core with Friends and Tech beside it. Patch 20.0 sped up Motherboard, Keylogger and Sat-Comm and raised GRN-W4SP Poison and RED-F1R3FLY Burn.

Season 20 builds
Critical Core
- Core pieces
- The Tech shell: Motherboard with Lens, Remote Control
- Why it wins
- Very fast Charge loops of Tech items set the pace of the fight.
- Weak points
- Damage is the weak point; it needs Crit and Damage skills.

Weaponized Core
- Core pieces
- Chronobarrier, Fiber Optics, Lens, Motherboard, Remote Control; upgrade in that order
- Why it wins
- Same speed as Critical Core, but it scales its own Damage. Chronobarrier slows only the enemy's cooldowns. Antimatter Chamber at Diamond adds item destruction.
- Weak points
- It fails when nothing disrupts the enemy while the Core scales. Atomic Clock needs at least 6 Ammo; Metronome replaces a missing Motherboard.

Launcher Core
- Core pieces
- Z-Shield, Thrusters, Micro Mach, Propeller Hat; a carry such as Terry-Dactyl, Ice 9000 or Launch Pad
- Why it wins
- It makes almost any carry loop quickly.
- Weak points
- Hotfix 20.1 raised its cooldown to 7 (from 6). It needs a full board to be useful, so keep it in the Stash until the board is unlocked.
Days 1 to 5. You pick a Core on Day 2. Before then, play Claw Arm with Cog, Pulse Rifle and a Small Friend, or Pulse Rifle or Rocket Launcher as a Medium Multicast item. Brick Buddy with Clawrence is the fallback. Buy Crypto whenever you do not need the Gold at once. Upgrade the Core through level-ups or Machine Learning, not with a flexible upgrade.
From Mobalytics' Season 20 meta list (9 November 2026); order is not a ranking. Sources and the other heroes: Season 20 builds. When to switch from an opener to a carry: day-by-day plan for 10 wins.
Mechanics
Core
Core Surge (19.0) enchants non-enchanted Cores at the start of each fight and Charges already-enchanted ones; Best Friend (19.0) turns a lone Friend into a Core.
Friend
Assembly Line (19.0) transforms the item to its left into a Friend from any hero at the end of each fight; Hotfix 19.2 lets it split a Medium or Large item into several smaller Friends.
Flying
Balloon Bot, Party Float and Propeller Hat start items Flying. Flying halves Slow and Freeze durations on that item. Rules in detail.
Hero-only encounters and notes
- The Cult Invitation event at the end of Season 16 stopped guaranteeing a Core for Dooley; the Oblivion Core can still spawn from it.
- A Core upgrade option was added to Dooley's level 11 reward in Patch 12.3.
Changed in Season 20
