Armor is a pretty big deal. Even if you're running around with THP and darkness, you getting armor helps a lot.I've pretty much posted this in my original post, without going into specifics of how to play, because I think people should already be able to read spells and figure out what works for a bladelock. What I don't recommend is multi-classing. The reason is, warlocks, like all casters still rely on their magic, and the short term gain you get from starting abilities of another class, usually turns into long term misery, since every level you take in another class, pushes everything in warlock back that many levels, and closes you off to your end game abilities. For example taking 2 levels of fighter first means, you don't get your first ability score improvement until lvl 6, and you can't take Thirsting Blade or get 3rd lvl slots until 7. You can't get life drinker until 14 and you lose master warlock and your last feat. If you take 4 lvls of fighter, you lose your ability to ever get a 9th lvl spell slot, and everything is pushed way back.
But you can get that with a feat, or as a dwarf.
Also, warlock 18-20 are kinda meh. Though you don't want to delay foresight, but after that I would take 3 levels of battlemaster.
archfey 7/rogue X with greater invisibility, booming blade, and warcaster.Someone mentioned multi-classing into rogue, that's actually kind of interesting, especially if your focus will be more on being a rogue with a pact blade. I'll have to look into it and see how that can work.
Hit someone with advantage, hide, and move to some random spot next to some other enemy. When they move, OA for more damage.
Works great. Not to mention all the fun utility of being Dex/Cha with mask of many faces and expertise in deception.
