Crystal of knowledge is a type of gem which can be used to map the area around the PC out to a radius of 10/7/5 depending on B/U/C status. Blessed gems can also increase Learning by up to 2 points. They cannot increase Learning if it is already at potential, and they become less likely to work at high attribute values, although technically they are capable of increasing Learning all the way to 99.


Useful for spellcasters, and to a lesser extent other types of characters for getting more skill increases. They have a reasonable success rate up into the mid 20s. The mapping effect can also sometimes be useful in scouting greater vaults or finding the wand of teleportation in VDDL.

Guaranteed/Common sources[]
