My suggestion is simple. Take a wheel of pain and place it on the pilgrimage road to volcano, so you’ll avoid spawn destroy. Every single named fighter or archer there is excellent balanced from pve to pvp, except devote.
Every single one is ready to fight from lvl 0 and defend you or your base, all you have to do is provide them an epic armor set and a couple stacks of gruel.
You don’t need to give them weapons, they spawn with obsidian ones, but I would suggest you to give to fighters at least dragon bone 2h greatswords. They will slaughter their enemies.
It will take you less than an hour to farm 8 named fighters or archers each day and ofcurce you will get great amounts of steel, crystal, etc… Since in volcano npcs these are main drops.
Keep Spinas for your personal guard, since firespark many years ago mention this thrall as a truck, I went seeking for him. Before the nerf 60% of the npcs were dieing on sight, you didn’t even see the animation of taking his sword out, it was awesome, freaking awesome, I really miss these days only for this.
Another great key is Teimos, this npc is a real universal warrior. His kind ends up really fast stunning fighters and stunning archers. Your base will be star wars with clone warriors 

. But, he spawns every 15 min, some times he doesn’t. That means in an hour farming (boring respawn anticipation ) maybe you’ll get 2, or none.
But fast level up.
There is a lemurian girl however, I cannot recall her name it is long ago, I think it was Mei, she was hitting really strong after lvl 10, really strong.
Berserkers have almost no survival so yes they hit hard but die very easy from poisoning or bleeding on 0 levels.
Relic hunters great hp, really fast farming, maybe 16 in an hour and more but only great vitality, they are not so trustworthy from 0 level.
Plus it’s annoying that fighters take archer perks and archers fighter perks… Go figure.
Heirs of North.
Lian , Dina, Freya… Main spawns.
They get enormous numbers 60 to 80 strength… Just numbers, unreliable thralls they go down very easy.
