DS2: SotFS - NO DEATH full run NG+ (Easiest route)

Idiot-proof and noob friendly route to complete a no death run and obtain the Illusory Ring of a Conqueror in Dark Souls 2: Scholar of the First Sin.

Start a new game and complete it the way you like.
Then get 24 ascetic bonfires, I highly recommend farming them in Aldia's mansion. Burn such bonfires to kill the Rotten that many times, he'll drop Souls of the Rotten and Old Dead One's Souls. With the massive amount of souls he yields build your arsenal: upgrade weapons and armors, buy a shitload of arrows and poison arrows, poison throwing knives, rings, brightbugs, lifegems etc.
In NG+ you'll consume 24 Souls of the Rotten and Old Dead One's Souls to instantly get ~2M souls and open the Sanctuary of Winter skipping a huge part of the game. Then progress normally till the end.

Playing strategy is pretty basic and straightforward: just abuse everything you have to make the game easier.
Use poison to cheese the absolute fucking of a beast that is the black phantom in front of Drangleic Castle and take down with arrows as many enemies as you can in Shrine of Amana. Those are the only times where you actually need to pay attention and play accordingly, everything else is stupid easy. Spam lifegems to keep your healthbar full, consume brightbugs, abuse items, use the strongest equipment, cheese enemies and level up your stats like shit and... you know the drill, git gud.

Seriously, it's easy if you know what you're doing.
