THE CORE SYSTEM: At Level 3, choose 1 of 7 Cores. Cores activate from items to the left and buff items to the right. Careful left-to-right positioning is everything. Freeze hard-counters Dooley by breaking the chain.
Playstyle
Build left-to-right chains. Items on the left charge the Core; the Core amplifies items on the right. The chain can create overwhelming cascades. Dooley struggles before getting his Core at Level 3 and is vulnerable to Freeze.

Expert Tips
Hover items to see the blue glow — it shows which items interact with each other.
Fast left-neighbor items (low CD) charge the Core faster.
Freeze completely shuts down your chain — build Radiant enchantment on your Core if possible.
Chris Army Knife is a Friend + Tool + Tech in one small slot — extremely efficient.
Key Items
When an item to the LEFT activates, The Core fires — dealing damage AND charging all items to the right by 1 second.
Place fast-activating items to the left to constantly charge the chain. Radiant enchantment is essential to prevent Freeze counter.
Hastens adjacent items. Charges when Friend items activate. Powers the Dooltron build.
Core of the Dooltron/Bug Squad builds. Place Friend items throughout the board — each Friend activation charges the Companion Core.
Deals damage and permanently increases the damage of all weapon items to its right.
Permanent buffs compound over a long fight. Pair with high-quality weapons to the right for exponential late-game scaling.
Applies Burn and enhances Burn-based items to its right.
Good early game (Burn is strong vs low HP), but falls off late game as enemies stack Shield. Below-average tier in Season 14.
A small item that counts as a Friend, a Tool, AND a Tech item simultaneously.
Incredibly slot-efficient. Counts toward all three category-based synergies at once. Essential in most Dooley builds.
Gives ALL Friend items on your board +1 Multicast.
Transforms the Bug Squad build — every bug Friend fires twice. With Companion Core, each activation triggers the Core twice. Exponential scaling.
Fast clock Friend that generates Shield while dealing damage. Powers the Dooltron build with Companion Core.
The heart of the Dooltron build. Companion Core hastens it; it activates quickly and feeds back into the Core trigger loop.
Charges by 1 second when the item to its LEFT is used.
Place a fast-cycling item (like Uzi, 3s CD) to the left. Every 3 seconds, Duct Tape fires for free. Exceptional slot efficiency.
Tech item that charges Dooley's Core quickly.
Placed to the left of the Core, Arc Blaster rapidly advances the Core's cooldown. Essential for early-game chain setup.
Applies Haste to all items on the board simultaneously.
Board-wide Haste for Dooley — every item cycles faster including the Core. In Stelle builds it triggers all haste-based effects simultaneously.
Freezes enemy items. Disruption tool for controlling opponent combos.
Place in a Dooley board to counter other chain-reaction builds. Freezing the opponent's Core or engine item breaks their combo entirely.
