I know ladder won't reset in a while but

What do you buy during 1st week if you can only spend eg. 100 fg?

I'm talking especially about weapons (also armor), because with casters you just make spirit sword quite fast

With barb it's confusing because dual wield (so many options / combinations). What are best weapons before you will make runewords that require hrs (botd, death, grief)?

Also with armor there are many options; lionheart, shaftstop, also treachery now since ias works from other equipment for ww

Early ladder u could consider:
Oath
Lawbringer

Some source of crushing blow is a good idea to help offset the lower damage of most early game items. Duress Armour isn't bad until u get better options.

Most unique weps are pretty bad for hell PVM.

Grief phase is king though and isnt a crazy expensive runeset.

Death for WW can work but you need alot of IAS to hit the breakpoint.
