A couple of must have here, poe-trademacro for sure
Stunning Sunder Berserker Build - Harbinger League Starter
Max Block Scorching Ray Necromancer Build- Harbinger League Starter
Fire Nova mine ( Fire Nova Mines is the most enjoyable build I've played so far. The combination of fast clearspeed, very cheap equipment and the possibility to run every single Map Mod without a problem makes this build the perfect first Character for a new league. You can get rich early on to farm up for your 2nd, more expensive, character.)
