Median XL - Diablo 2 Mods by Brother Laz modsbylaz.vn.cz.
If you find an item with extra sockets, you can fill up the sockets before the rune with jewels. Each runeword contains only one rune, but this does not mean you can only make them in items with only one socket. 201 of these can be inserted into weapons of various kinds.
There are a total of 332 new runewords in Median XL 1.F9B.
