Aion players will have the opportunity to head back to the dreaded Shugo Tomb with the arrival of the in-game event that is slated to run from May 22nd through June 12th. Players can score some pretty awesome stuff by participating.
The Shugo Imperial Tomb is back and just as you remember it! While inside, you are transformed into a Shugo with special abilities only available inside the instance. Protect the ancient towers from the waves of looters that will try to destroy them. Use special items found off of the spirit enemies that appear in-between waves for an easier time. When the boss monsters appear, defeat them to earn map pieces, keys, and Tags into one of the three treasure rooms!
