The opal crystal was one of the several types of Force-imbued tasar crystals that could be found on the Inner Rim planet Tasariq. It exhibited a rainbow spectrum of colors and shared its name with[1] the type of gemstone known as opal.[2] If an individual carried an opal crystal on their person for a number of months, they gradually became attuned to it and as a result became able to use—even if they were not Force-sensitive—the battle sense Force ability.[1]
Behind the scenes
The opal crystal was mentioned in "Tasariq: The Crystal Planet," a West End Games' Star Wars: The Roleplaying Game source article written by Tom Moldvay and Steve Miller and published in the November 1997 fifteenth issue of the Star Wars Adventure Journal magazine.[1]
The article suggests that, if the player characters are mining tasar crystals on Tasariq, they should have a chance of discovering Force-imbued crystals such as the opal crystal, with the probability ranging from one-in-six to 1-in-216 of finding one or three such crystals, respectively, for every seven days they spend working in an area with an abundance of crystals. Additionally, the article suggests that, should the gamemaster player wish to determine randomly what crystals in particular the characters discover, the chance of obtaining an opal crystal be one-in-thirty-six.[1]
