Here's the guide for both builds:
During Early game, Always start with Weapon Blade and Sharp Shooter and a pot. Unless the enemy team both got same damage output like Double WP or vice- versa. Follow the Nuke build if you have squishy enemies and follow the Brawler build of the enemies are tanky, have lots of sustain or if you can't outrun them. For boots, always take Journey Boots. It compliments his kit. Activate it, gain distance, and take advantage of the long range slow from Achilles' Shot(A) while lowering the cooldown timer. Or, unleash yout Ultimate onto a target the activate the boots after the channel so that when the Ult lands, the boots' cooldown lowers too.
For the Brawler build don't be afraid to fight enemies with high defenses. Just stack up everything from your build and unleash mayhem to the enemy team. You could even focus on the Captain or Tank and then watch the enemy carries crumble.

Last but certainly not least, build defenses. Just please, build at least one depending on the situation.

So that's it for this build, hope I helped lots!

I decided to join the contest and this is my first guide XD
