For the ghosts it's pretty quick. I knocked out most of them in an afternoon on my Titan. There are a few that are only available in certain weeks (ie the three from tier 3 CoO) but most are pretty easy. Google destiny calcified fragment tracker and u will find a few sites to choose from that will show u which ones you need and link to video guides. The order of them even makes sense for picking them up. The first 25 or 30 are just scattered around the dreadnaught on patrol, then there are several through different missions and strikes (they are tied to the areas and not the strikes themselves but some of the areas are locked off except for during certain missions). You should note the tracker sites are all based on grimoire so if you've picked one up on a different character that u don't have on your main, u will need to track it down. There is no way to tell which ones you've gotten on which characters. The court of oryx tier 2 are a bit random but if you have some stolen runes to burn through you should be fine. You will have a better chance of finding people there if you walk through the hallway right of spawn after passing the patrol beacon rather than run as it will give the game more time to matchmake you. If you already have the raid ones, you should be fine. You only need 45 of the 50 so the few that are in a weekly rotation won't be enough to stop you. As for the sword, go classic free for all. You don't need to have a charge for the sword and can just beat people with the hilt and it will count. Just need to play smart using corners to your advantage. You may even run into someone else doing this or that recognizes what you're doing and give you the odd free kill. You can also take a friend into this playlist to kill if you really need to. The competition is generally easier in here compared to normal rumble and a lot less people are using all the best gear. Plus in rumble u can clean people up that are injured. I actually won a match with mostly hilt kills when I was doing this.
