The by-product of Goblin technological weapon research during the old War, Rattletrap the Clockwerk Goblin was shut away into storage for countless decades until the Sentinel found and reactivated him. Combat-wise, this goblin's capabilities know few bounds; his body is stocked with a huge array of armaments that destroy targets both near and far with ease. However, his mettle has yet to be proven to his Sentinel comrades.

This short guide assumes you're already familiar with this hero. If you're not, you should probably check out the Clockwork Goblin DOTA guide first. It'll explain how to play him during a game.

Here's a selection of popular items for Clockwerk and our thoughts on them:

• Dagon: This one doesn't make any sense, but I see it often in DOTA pub games. Perhaps people miss their hookshots, or try for rocket flare kills?
• Mask of Madness: A great item for any occasion. The extra attack speed is a godsend while someone is trapped due to power cog. You can also use it to chase after heroes who you might've missed. A much better solution for Rattletrap than that energy burst Dagon stick.
• Cranium Basher: It works well when mixed with attack speed increasing items. This'll help you survive your prison ambushes and has a good stun synergy with battery assault.
• Satanic: Much like the mask of madness, toggling this while you've got someone trapped will do wonders. The lifesteal bonus should (if both DOTA heroes are on even standings) always give Rattletrap the win.
• Shiva's Guard: Works amazingly well mixed with hookshot. This is a great way to begin fights with your teammates if you work together. You can also use it combined with hookshot & an escape mechanism to harrass effectively if no one can disable.
• Aghanim's Scepter: Greatly improves your ultimate. Whether or not it's worth it all depends on how much you like clockwerk hooks. The upgrade has another bonus! It lets you hook on to allies, dragging you out of combat. Be careful however if you're used to aiming them through your friends...
• Heart of Tarrasque: This is often a poor choice due to Rattletrap's lack of damage normally. Save it until later in the game if you'll need it. The goblin works best taking people by surprise, or at lower than normal health from previously hitting them with flares.
• Lothar's Edge: Allows you to sneak up for that surprise battery and cog. It's fun! Being invisible also lets you save your hookshot to get out if you have to.
• Phase Boots: A very bad choice! Not because they're bad, but because they don't let you escape from your own cogs. This is something to easily forget during a hot & heavy team battle.
