List of drop-only gems

There are several methods of obtaining skills gems:

• As a reward for completing a quest (see Quest Reward Gems).
• Purchased from town vendors once a certain quest is complete.
• As the result of a vendor recipe (see Vendor_recipe_system#Skill_Gems).
• Random drop from monster, chest or strongbox.
• Random offer from a master (see here for a list)

Since the latter two options are random, some gems are more difficult to obtain and potentially more valuable.
