So I'm not saying we should do the level 26 raid, but I hear it's fun. Oh, and also it's called Vault of Glass. Get it? Otherwise known as ... VoG? DOESN'T THAT MAKE YOU DOUBLY EXCITED TO LEVEL!? No? Okay, I tried. Seriously though, if you're interested in doing this raid, to get to level 26 is definitely obtainable if a little janky. I'm level 25 at the moment, and I think gear gets better and better depending on how much light you have on it. I mean, i keep getting better pieces to replace my old ones. I recommend doing the strike playlist to get your vanguard marks/reputation and then missions/bounties for more reputation to ultimately get to rank 2 vanguard so you can buy some legendaries. Meanwhile, doing the infamous loot cave on your off times seems to help with materials and the occasional lucky drop. I got 3 legendary engrams tonight and all 3 gave me strange coins (still pretty valuable though .. hold on to those for the weekend vendor in the Tower). I should note that I did get a legendary from a blue engram. Anyhow, hope those tips help you for leveling past 20. Perhaps at one point we will all be able to get to try this raid. :)
