Try not to be the main tank. Your kit is not ideal for peeling & protecting your carries. You are a diver, an anti-carry. Some people consider and play Noc as an assasin, but unlike some assasins, you don't have an escape mechanism. Early & mid game you are an initiator on out of position squishies to instagib them. Late game though, once team fights start, it's harder to catch squishies & just blow them up. Usually their team is around & you don't have an escape. As such, you HAVE to build Noc as a tanky dps, so you can soak up a good amount of dmg & still be able to do your job, while giving your team time to follow up. Noc is one of the best split pushers in the game, and that's how I play him. So I don't prioritize Aura items. The most important thing about playing Noc is awareness, awareness of where ur team is, where the enemy team is, when potential team fights are about to start, having your ult up to go in, or to be close to ur team if it's not. Also, don't dive headlong into the enemy team unless you see them way out of position. It might be better to wait a second or two AFTER the team fight starts, to ult in on their carries. Gl hf!
