Raw Blue Crystals

These crystals are known to augment arcane power when refined properly. The specific technique used to refine the blue crystal will result in a different magical effect. For example, the Arcane Power Gems refined by Rowan Lestrin double one magical effect. Vekkin Tal'Vo is also proficient in his own technique, which produce Arcane Upcast Gems that upcast spells by one level.

In their raw state, raw blue crystals release varying amounts of arcane energy when crushed, depending on size.

Many raw blue crystals have been found in Irondeep and they are abundant in the Underdark .
