Cyberpunk 2077 - Quick & Effective Weapon Skill Trees XP Farm, Patch 1.63
Location seems to be pretty common, route was developed by me. Works out well with Annihilation, Street Brawler, Assault, Handguns, Blades and Engineering skill trees. For a decent buff, you can sleep in a safehouse before going for grind and it's not recommended to fast travel as it might glitch the buff making it display but don't speed up the process. Some enemies may bug, in this case you should reload the save file. Plus as you might notice, in some spots enemies don't respawn but most of them still do.
So if you don't mind grinding for skills or just wanna max out the skills for perk points, go for it.
