To address your actual questions.... 1. Raids need a pre-made fireteam of 6. It's possible to do it with fewer on Vault of Glass or Crota's End, but 6 is highly recommended. You will need to either manually invite friends or acquaintences from a Looking For Group (LFG) site or from your personal friends list. There is no match-making (the conversation about whether this is good or bad is for another day). 2. Nightfalls are strikes that rotate once a week. "Reset" day is every Tuesday, and every reset, you'll get a new Nightfall strike. There is no matchmaking for this unlike other strikes, so like Raids, you'll have to bring your own fireteam, or solo it if you dare. The difference is that these Nightfalls offer harder enemies, there are modifiers to make certain types of damage go higher (ex. Solar Burn), as well as other modifiers. When you bring up the Director (where all the planets are), you'll notice 4-5 modules on the lower left side of the screen. That includes all of the daily and weekly activities. You'll find the Nightfall strike as the right-most module. 3. Absolutely finish the story first. You'll get a better idea of how the mechanics of the game work this way, plus you'll get a ton of experience along the way to level up your subclass. Some end-game content, like raids and nightfalls, won't even unlock until you do this anyways. This is probably a rehash of what other guardians have said, but it bears repeating. I'd offer to play with you, but I'm rarely on my PS4 character. There's so much to do now that I can only really focus on one character, and that one is on the xbox. As far as general advice goes, I'd just keep playing and running around. -Play with friends if possible. -Grab bounties every time they're available and complete them. -Join a faction. I'm personally a Future War Cult guy, but it doesn't matter, really. You can pledge an allegiance to one faction at a time. -While on your way to lvl 40, only use the best equipment in your inventory, regardless of weapon type or perks. Once you hit 40, you can be a little more discerning. -I wouldn't worry about infusing weapons or armor if they're under 285. Don't worry! They'll drop for you, but only once you hit lvl 40, and even then, it's a bit of a trickle. Not sure how proven this is yet, but here's what I do when I turn in engrams. I decrypt them one at a time, and then I check it to see if it's higher than what I currently have equipped. If it is, I equip it and then decrypt the next item. You don't even have to leave the menu, really. The idea being that engrams decrypt (blues/purples) at close to your current level. Often they're below. -Xur shows up once a week on Friday morning and leaves on Saturday night. He sells exotic items at random. DO NOT BUY legacy engrams from him unless you want an exotic item at attack/defense values too low to use currently. The good news is that it will unlock a Year 2 blueprint if/when the Year 2 version is available. Your strange coins are used for this. Don't ever let anyone make you feel bad about buying something from him. -Go ghost hunting! Seriously, find dead ghosts. It's a fun way to pass the time if you haven't done it already, plus it'll unlock Grimoire cards. -Use shaders! They're available in the tower from Eva Levante, who is in a corner in the same area as the Speaker, or they can come from random drops. -If you like lore, read the grimoire. The full thing is available [url=http://destiny-grimoire.info/]here[/url], or if you want to only read the ones you've unlocked, you can enter your GT or PSN ID and it'll only show the ones you've unlocked. I'd personally recommend anything that says "Ghost Fragment." -Bungie releases a weekly update article every Thursday. Make sure you read it, because it's got a lot of good information in it. That's kinda the gist. Obviously, play the game how you want to and make sure you have fun!

Welcome to Destiny guardian! Raids are the highest level end game content. You can't do kings fall, until you finish the story all the way through, learn the mechanics of the game and how the community operates, and are at least 290 light. The year 1 raids are easier but will require you to be at least level 34 and 170 light or so. In order to do raids, you need to get your own fireteam together with your friends, or use LFG, which stands for "Looking For Group". That should be self explanatory. There is no matchmaking for the raid, or nightfall. The Nightfall is a weekly event. It is a randomly selected Strike mission, however it is the highest level of difficulty, and has a bunch of modifiers to it that make it even harder. It changes each week, and once you complete it the first time that week, you will no longer get good loot drops or leg marks. But the final boss can still drop loot. Unless you're light level 260 I believe, it won't allow you to do it, or something like that. Basically you need to get your character light level up to be able to complete it. Make sure you tranfuse gear and weapons and don't dismantle anything unless you're sure it's useless. Just to be safe. What system are you on? If Xb1, let me know as I'm always down to help people with stuff.
