Clockwerk is a melee character. His primary attribute is strength. The hero is mainly taken in the hard lane on the 4th and 5th support positions. Most effective in the early and mid game.
A dangerous character for non-escape heroes. For such characters, the combo of Battery Assault and Power Cogs becomes a formidable weapon. Rocket Flare provides Clockwerk vision anywhere on the map, which is very beneficial when ganking or pushing. Hookshot is an ultimate that can be used to dramatically shorten the distance to an enemy hero who wants to keep the distance in a fight. Aghanim's Shard allows Clockwerk to learn the Jetpack ability, which allows him to get even more vision during fights and fly over obstacles. Aghanim's Scepter helps the hero learn Overclocking, which allows him to move and attack enemies more efficiently during fights.
