Iron banner will be here next Tuesday and will last a week long. You get a 310 artifact for reachng rank 3, and a 310 ghost plus a 310 - 320 piece of gear for hitting rank 5 per character. After you reach rank 5 you also have a chance of a ghost dropping 310 - 320 as a post game reward. You can do this for each character. Nightfall is another way to get gear that can be 300+ as a post game reward, but it's not always guaranteed. This week I only received 290 ish gear. This can be done once a week per character. Raiding is another option. The best gear you can get from normal mode will be 310, and hard mode can net you 320 gear. Doing the challenge mode (which changes weekly from war priest to golgoroth to oryx) will give you a guaranteed 310 artifact and piece of gear for normal mode and a guaranteed 320 artifact and piece of gear for hard mode. This can be be done once a week per character per difficulty. Getting your exotic sword would help if you don't have one of those yet, as they always drop at 310. Other than that, your other option is to wait for another timed event that offers gear rewards. Sparrow racing was giving up 320 helmets and 320 class items as post game drops after you reached rank 3. Crimson doubles offered 320 ghosts as post game drops. No word on when or if these game modes will be back or what they will offer, but hopefully Bungie will keep implementing timed events with worthwhile rewards. Edited: Mentioned challenge mode drops in raid.
