In order to run a mod, Diablo II needs to be patched correctly, or the mod will most likely not start at all.

Might work with Patch 1.11 as well, but it is recommended to run on 1.10. Below is an incomplete list of mods and what patches they work with. Many popular mods for Diablo II require different patch versions to run properly. This guide aims to explain how to do that. Diablo II: Lord of Destruction - Stra-D2Mod v.1.20: mod: 472.1 MB: : 32.7K: 115: Diablo II: Lord of Destruction - Diablo II 1.14d - Mini Fix: mod: 1.7 MB: : 11.9K: 72: Diablo II: Lord of Destruction - Diablo 2 LoD 1.13 Content Update Mod v.1.5.7.1: mod: 69.8 MB: : 13.3K: 38: Diablo II: Lord of Destruction - Median XL. Many players however wish to have one or more mods installed at the same time, as well as a regular, or 'vanilla', installation of Diablo II intact so that they can play on. This is because most mods change many of the already existing game files, and they are often made for different patch versions of Diablo II as well. While installing one of these might often be simple enough, removing the same mod or installing a new mod often causes problems.

But the only build you mentione di recently played was the Ww Barb. 'to the worm in horseradish, the world is horseradish.' Unfortunely 1.13 didn't change alot of the build scenario. There are many different Mods available for Diablo II. i think the only new builds ive seen since 1.13 are firewall sorcs, which are decent.
