The way to remove Gems from a socket is to use the Horadric Cube, an item that can be obtained from the bottom floor of the Halls of the Dead in Diablo 2’s second act. To unsocket and remove socketed gems, jewels, or runes from items and gears in Diablo 2 Resurrected, you need to unlock Horadric Cube in Halls of the Dead dungeon in the Dry Hills during Act 2 to use a Hel rune, a Scroll of Town Portal, and the socketed item, and then click on the Transmute button. You can use the jeweler to remove gems from sockets. It can only be socketed into helms, and is obtained by completing the Darkening of Tristram event in January of each year. The game writes this both ways at times.Red Soul Shard is a Legendary Gem in Diablo III.
Runewords almost always have a Clvl equal to that of the highest level rune in that Runeword.
Only the Hel (r15) Rune does not have a Clvl. Clvl: A character must be this level to equip an item socketed with this rune.All Runes have the same stats when in a Helm or Armor, and only two have different when in Shields.
To upgrade runes you are required to use 2 or 3 runes (plus a gem) of the level below the one you want to create in order to make 1 rune of the wanted rank.Runes only impart their stats once they are socketed directly into an item. This is the Diablo 2 runes list of all the runes in Diablo 2.
