I would say try using Troll King with a HP regen build on 5 medium 2 heavy or a mighty Chudan (you can basically run turn evil instead of mass hysteria easily without fear of losing out on major ward/resolve while getting more dmg from fighters guild passive) also on 5 medium 2 heavy. Bloodspawn has a lot up time with NBs being sneaky and the ult regen isn’t as useful as some other classes imo. Your other 5 piece sets can be offensive sets or sustain sets because you’re building more defensive on monster helm (new moon acolyte coming up soon, hunding’s, bone pirate, etc). This also depends on what weapons you want to slot but I think most NBs slot 2h + bow.
It’s a tough order but you’re best off with 2h/DW. Shacklebreaker and spriggans with BRP DW on your DW bar breaking spriggans, 6m-1H. Idk if you can really call it a brawler.
It might lack the tankiness you’re looking for and someone mentioned reactive armour as good but haven’t tried it. Issue with stamblade brawlers is how to get sustain and defense in one build, shacklebreaker is a good sustain set and BRP dw for tankiness but I’m not sure how to solve that puzzle.
Looking for any guildies I used to play with:
Havoc Warhammer - Alair
LoC EQ2 - Mayi and Iskiab
PRX and Tabula Rasa - Rift - Iskiab
Or anyone else I used to play games with in guilds I’ve forgotten
Shackle / truth front bar / masters bow back bar / trollking. 5h/2m 2h/ bow Tri enchant everything. 29 hp khajiit using vigor, dark cloak, troll king and rally for healing. Artaeum broth.
Dizzying procs truth next patch. Shackle, heavy, khajiit gives the mag sustain for dark cloak and what ever the other morph of barrage is.
Should have about 29k hp, 31k stam, 16k mag, 25k resistances, 4k+ weapon dmg, 1k mag recovery, 1600 stam recovery, 4k health recovery with tk procd. Lots of ways to build it though skills.
