This is a bomb/spirit build centered around doing as much damage as possible with your combo. The combo is Hook -> Uppercut -> Bomb -> Echo -> Bomb.
Early game you want to build as many bomb stacks as possible so make sure you're using it on cooldown and trying to secure the kill after a hook combo. Late game you want to initiate fights by hooking someone into your team or getting solo picks if you're very fed. Also make sure you're using your ult as much as possible to secure kills/win team fights
