Maybe as "stealth", you don't look on armor value, so you have great chances (or 100%...) to deal a crit. In this case, even the most basic knife is lethal in any caseInteresting… at lvl50 I have now maxed cool attribute and with just basic knife is almost assured hit/kill for normal npcs including city centre. And I don’t even have maxed inflicting damage due few missing perks. Is fact that I get used aim on head and attack from ‘shadows’ without rising alarm, but imo this fit to this playstyle. There are also some nice hacks for lure away npcs in packs. And I play on highest difficulty.
