Rattletrap, the Clockwerk Goblin, is an exceptional Strength-based initiator and ganker in DotA 1, renowned for his ability to disrupt enemy formations from extreme distances. Boasting a massive natural Strength growth that fuels his frontline durability, Clockwerk specializes in separating high-value targets from their allies. By trapping enemies inside an electrical barrier, tracking them globally via scouting missiles, and latching onto targets from screens away with a high-velocity hook, he acts as an oppressive, map-wide menace who thrives on chaotic isolated skirmishes.

2. Power Cogs
The Clockwerk Goblin ejects pieces of inner core to form a circular barrier around himself, trapping nearby units in with him. These cogs require a fixed number of attacks from an enemy to be destroyed before their expiration time. If an enemy unit with mana goes near an element from the outside it gets shocked for magical damage, knocked back, and loses mana. An element powers down if it shocks a unit.
- Damage Type: Magical
- Attacks to Destroy: 2 attacks from an enemy unit
- Mechanic: Creates an impassable block for heroes without clipping abilities. Outside enemies touching a cog suffer instantaneous pushback and resource drainage.

Item Build Guide
| Phase |
Recommended Items |
Strategic Purpose |
| Early Game |
Bottle, Boots of Speed, Magic Wand |
Bottle sustains his constant mana needs for Rocket Flare spam and setups. Fast boots are vital for positioning close enough to trap heroes with cogs without needing to blow Hookshot. Magic Wand provides emergency resources during deep dives. |
| Core Items |
Blade Mail, Aghanim's Scepter, Force Staff |
Blade Mail punishes enemies trapped inside Power Cogs with you who try to fight back. Aghanim's Scepter dramatically upgrades his utility via Overclocking, while Force Staff lets him push himself out of his own cogs to trap an enemy inside alone. |
| Late Game |
Shiva's Guard, Pipe of Insight, Heart of Tarrasque |
Shiva's Guard adds needed armor, lowers enemy attack speeds inside cogs, and gives an AoE burst. Pipe of Insight protects his team from magical retaliations during initiations, and Heart of Tarrasque makes him an unkillable frontline tank. |
Quick Gameplay Tips
- The Isolated Assault Pindown: Battery Assault distributes shrapnel randomly among all nearby targets, including lane creeps. To maximize its damage, use Hookshot or flank to catch a lone target away from their creep wave, then deploy Power Cogs immediately. Isolating them guarantees that all 15 instances of damage and ministuns hit a single hero, completely preventing them from casting spells with standard animation windows.
- Global Rocket Scouting and Securing: Rocket Flare provides 10 seconds of flying vision over its target area. Use it constantly to check the Rosh pit, scout out enemy neutral camps, or spot incoming enemy rotations in the river. Additionally, because the missile travels rapidly across the map, it can be calculated to snipe low-health fleeing enemies deep behind their own tower lines.
- Cog Positioning and Outside Splitting: You don't always need to trap enemies inside Power Cogs. If an enemy hero is chasing an ally, positioning yourself just ahead of them and deploying cogs can knock the chaser backward due to the outer rim shock mechanics. This effectively burns their mana and creates a massive terrain blockage that completely kills their pursuit angle.
