Crack in the Slab is pretty simple nonlethally outside of a couple of instances . Not having powers for it can feel a bit off to begin with , but my advice would be this stay in the present as much as possible and clear it out from bloodflies , keepers and dogs . Now you have free reign to just warp to present everytime you could be seen . If you ' re having trouble staying hidden then work on using blink more for now I would say . Honestly blink is kinda easy mode once you know to look up . Are you going for all the runes and bonecharms ? If you ' re not , do that , as they are usually located in places that force you to explore . Pretend the floor is lava and stay high as much as possible . Regular sneaking without powers is tough , and intentionally tough . Have you done the game lethally ? I ' m sorta assuming you have , maybe using the shadow kill perk ? I know a few people who played D 1 with shadow kill , then when they played nonlethally kinda got stuck , as they had the mindset of ' Remove obstacle ' rather than ' Circumvent obstacle '. Really , there isn ' t much difference between nonlethal and lethal you ' re slightly more resource starved Assuming you rely on sleepdarts , easily rememdied by not doing so , removing an NPC from play takes slightly longer , and the target encounters play out slightly differently . You don ' t need to be overly creative to get past guards I think I threw 3 bottles to distract guards in the whole run , just chuck the bottle at a wall and when they look , blink past them . Keep at it . It ' s very doable . There ' s also no rush If you ' re in a location and no guards can see you , take your time ! If you ' re in a position where you can be spotted , ask yourself if it was necessary to be there . Usually the answer is no and there is a much cleaner Although less videoworth method of getting where you want to go .
