Aion Introduction Stigma Stones and Shards

After the completion of the Stigma quest in Aion, you may want to learn some new skills. Then the item you need most is the Stigma stones. There is many a source to obtain these stones, but not all of them are easy.
Stigma stones can be gained as a reward of the completion of a quest, or can be obtained by looting the mobs (though some mobs are really tough to grind). It is pleasant that these stones can be used in trade, therefore you can buy them from other players too. This choice allows more room for decision. For instance, if you do not have enough time to grind mobs to loot these stones, you could buy them from a player immediately.
Stigma shards are used to enhance the Stigma stones. It is advised to store more shards than you currently need, so that you could save a lot of time in the future.
