Classic HU thread for information on other HU versions like 1.21z.
For HUv1.3f, hopefully one of these works:
Easy solution (it kinda already exists):
Blue's Website is some version of 1.3 (probably 1.3a, but I wouldn't be surprised if it were updated to 1.3f) and hopefully there aren't many changes between it and what you're playing.
Best solution (do it yourself now and for any D2 mod you want in the future):
If you're able to
unpack the .mpq file so you've got access to the text files in the excel folder, then you could use the
Webpage Maker to produce the pages. The main instruction to follow is editing the Properties.txt file (you could copy-paste the description column from the file that comes with the webpage maker, but it won't be a 100% match for v1.3f, you'll need to use some common sense about which property descriptions need to be changed).
A solution (I've got time at the moment):
Alternatively, I don't mind using the Webpage Maker on the version of 1.3f I found
here. A downside is that I didn't fix any of the bugs, so it's about 97% accurate (The webpage maker requires consistency and when it finds an oddity it just skips that item (its output tells you what it skipped and why), so some items are missing (e.g. Rattlecage, Razor's Edge, etc)). I'd just use Blue's site for those.
