GoMule is something I have been working on for the last two years. It is probably best descibed as a free, open source, multiplatform Java based muling application, assuming you know what muling means! If not, then it allows you transfer items from one character to another, or from one character to a storage file (and vice versa).

It also includes a dropcalcuator so you can see where you should be farming and a lot of character information to save you all that counting on your fingers.

So you're running Pindle a lot. A LOT....but you can't work out what your runs/min is and having to mark down each run you do is starting to slow you down. You need a run counter! Here it is.

Works by counting the number of times that the file saves, so it's only good for short bosses, unless you set it to count more than one save as a run.

Colour Rune Mod, or CRM was my first jump into Diablo 2 modding. For quite a while, the Red Rune Mod (RRM) had been hanging around, so I figured that something which exploited the rest of the colours and made it easy to change between them would be a valuable application.

As it turned out, multiple colours are apparently not equivalent to just having red runes, which was a shame. Still, it's a fun app for you all.

This is the standalone version of the dropcalculator, in case you don't want to use the one that's bundled with GoMule.
