Boneshatter Juggernaut Build — The best melee League Starter build in Path of Exile Trial of the Ancestors 3.22 

Build Guide: Boneshatter Juggernaut by Zizaran

Melee has been in a really strange place for a while in Path of Exile. However, recent improvements to Boneshatter have made it extremely viable, especially at the league start. Its damage scales very well even without optimized gear. So long as you can get a decent weapon, you don't have to worry about damage with Boneshatter. By going Juggernaut, survivability is also improved making this one of the best all-around melee builds PoE has to offer POE currency trade. If you are playing in non-hardcore, or have more experience with PoE, you could also try Slayer. Boneshatter Slayer won't have quite the survivability as Juggernaut, but it will do more damage.

Explosive Arrow Ballista Elementalist in particular became a strong build a few leagues ago. Every league it's assumed it's going to get nerfed, but that's yet to happen. This build does not require any Uniques so you can literally start decimating bosses and clearing maps without any investment into your gear. In fact, with the most basic of gear, you can start clearing maps as soon as you reach the end game. As if this wasn't enough adding optimized gear only pushes this build even further. This means that while most League Starter builds eventually reach a cap where you have to switch to a better build, Explosive Arrow Ballista does not have that problem. Once you start clearing maps and farming currency, you can actually reinvest in your same build and eventually clear all content with it Path of exile currency.
