Daily Quests are repeatable up to a total (for all Daily Quests) of 10 times per day. The count can be reset to zero by purchasing and using a Daily Quest Ticket from the Item Shop (for 39 ($1.16)† ) or from any Phirius Merchant (for 780 ).
Enter the portal and prevent Sismond from breaking the seal.
Once inside, attack the Energy Storage Rune. This will cause many more Energy Storage Runes to appear. They have 4.7 million HP so you will need a party at least. This place deals a lot of area damage so you will also need good heals. You must smack and destroy them as fast as you can to keep Sismond's energy levels down. Miss one and be prepared to be smote mightily.
Fail and you will revive just outside Balu Village but your tombstone will be just inside Kidd's Grave.
It seems that it is not possible to solo this, as you really need to smack more than one Energy Storage Rune at a time, but Ancientgear (Erebos server) assures me that it can be done.
