The only stat that thralls have is HP therefore the only way to tell which thralls are better is by their hp stat, it’s not complicated. I do SP so I need the best thralls backing me so I can take bosses meant for multiple players. The best thralls are the ones capable of doing more and longer fights before they run out of HP, even the best armor in the game won’t make a thrall invincible, The order of worst to best used to be: Exiles, Darfari, blackhand/lemurians, dogs of the desert, relic hunters, Heirs of the North, Forgotten Tribe, Votaries of Skelos. The issue is it’s a place even a solo player can easily set up shop and collect thralls at when only lvl 10 with starting gear, and you can get the best thralls, the original order was good, that being said the position of giving them stats to where there isn’t a clear best would be a better idea. Give players willing to build in the more inhospitable places a reward of better thralls, since the relic hunters match the Votaries there is no reward for being gutsy enough to build in the volcano, even worse is that at least the volcano is only hot, not many strong creatures in that location. The most dangerous location to build near areas with capturable thralls at is the Cimerian area, the creatures are strong the undead inflict corruption and aren’t staggerable, the Cimerians are tough as nails and hit extremely hard, this should translate to the thralls through means other than they start with hardened steel for normals and star metal for the high levels, Only the relic hunter treasure hunters should be at a match to the votaries as they are in these dangerous areas, like the mounds of the dead and unnamed city, they are already better than the normal relic hunters.
