Unfortunately, if you kill a rat/squirrel/shroom beetle the game cancels your Quick Serpent buff. Rapids is much more reliable. I still wear VO while farming because I don't need night's silence on my vampire stamblade and I cba to change my gear, but I wouldn't recommend it to someone trying to max their harvesting.Why would it be necessarily stealthy? Overland mobs are so weak they simply splatter at the first hit. In fact you can use that to your advantage by equipping Vicious Ophidian (Craglorn trials) set on a stamina character, ideally Orsimer (speed bonus) Stamina (medium armor speed bonus) Sorcerer (great AoE damage, you can also get major expedition from Hurricane Too), with the other set being Jailbreaker (Banished Cells). See a rat or wolf next to the node? Boom: major expedition and stamina back to sprint to the next. This way you add some more leather to your silk, wood, ore, runes and plants
