League started with arma brand as I wanted to try something that took advantage of the new Elementalist buffs, but wasn't a fan of the DI playstyle or trying to snipe bosses with Fireball. Made it to endgame and then rotated onto another build, came back once I had more currency and decided to push it a bit further. Not nearly as OP as Cold BV, but it was able to comfortably handle all endgame content, and was able to run Maven / Feared, etc.
The main build mechanics are arma brand + WoC applying ele weakness and despair for offense, and 5 golems(phys dmg reduction/life regen/taunt) + 40% MoM + Blind + Block + Arcane Cloak for defense. Arma brand has some nice interactions with Elemental Overload, frenzy charge on hit, and short duration ignites due to the way the skill quickly hits repeatedly over the duration of the brand, meaning we don't need to worry about using a secondary skill to proc anything as you would in a build that's hitting less regularly. The “auto-aim” on brands is also really helpful for some of the more hectic boss fights, as casting anywhere roughly near the boss is usually enough to get it into attachment range, and from there the brand will track any further movements the boss makes.
Overall price for the build wasn't too crazy (~60 ex) as most all the gear was self-crafted, and some of the more expensive stuff is definitely not necessary to have it run nicely. League starting this I cleared UE with a 6L searing touch, 50c cluster jewels, and no watchers eye or awakened hextouch. A few of the choices (like not running Flame Wall) were intentional so as to not mess with EE applied by lightning golem, but as this was something I made up as I went along I'm sure there are definitely improvement points. If there is anything glaring I missed other than crafting a more GG weapon I would be curious to hear.
