BBoU was already very playable before, and GGG graced us with ~27% more damage for it this league. This makes the damage quite competitive even on low investment.

Check out this build of the week as well as jungroan's video for detailed explanations, gameplay tests, and field proven pob's.

These are what I have come up with, not yet tested in game:

Cheap starter set up uses brands: https://pobb.in/XtAgg7cKXkh7

On higher investment, I got better numbers and comfier gameplay with jungroan's one button setup:

Swap to cocs: https://pobb.in/GBbyfARBfyEH

Higher budget: lightning coil variant https://pobb.in/OartAKOKLn_L and rare body armour variant: https://pobb.in/xGInvzdKXX_H

Further scaling is awakened gems, better rares, and melding/mageblood/forbidden jewels for tank and dps.

I will leaguestart this myself and refine it as I go. For a safer bet follow the linked build of the week, it is very well detailed. Any suggestions or recommendations welcome!
