The TLDR 2H Barb

No it is not, doesn't work with weapon damage skills.

Whats the best trophy to cube with the sleep charm?
currently trophy hunting in all ubers but 130's (as i'm only lvl 126 atm :p)

Depends if you consider expensive RNG ones or something more reasonable.

jitan and roll 5% ds (big rng)
rathmna square - lot of crushing blow which is huge value vs trash

expensive/hard to get ones ofc stuff like astrogha
laz trophy being great with max life and res

usable over su labrys? not sure about which proc does what

Figured it out. If anyone else has an issue figuring out ias breakpoints you have to download the calculator and then put the WSM column for your chosen weapon (25 for labrys). TLDR: labrys ias breakpoints - 29, 42, 63, 92, 147, 280.

How do I "install" and use the script? Not used to them in games

how op is barb i need an easier time with the game its too hard

It is good build to progress and get charms, learn the game.
For farming areas, so killing a lot of monsters as fast as possible with MF, I would not recommend it, there are much faster builds out there for that.

Aerial u gonna post a Samael video?

No plans, you need very good items for this to be viable, you need to unlock the quest which can take tons of farming, it is against the principle of the guide - so people can fairly easily copy it and do it themselves.
Same reason why there is no Laz video. While laz doesn't require crazy gear, it is very difficult to do, multiple times harder than for example void.
