Stand Here!
Stand in the chest of the fallen guardian at 37.7, 23.2 (as seen in the picture at right, between the west gate of Fierce Fang Front Line and the Resurrection Circle). You can reach all three of the sparkly Guardian Remains and they will respawn faster than you can collect all three.
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 ).
In all other zones they do not reward XP, TP or Gold, only Public Event Points. In all other aspects they are the same as a Daily Quest (except for the infinitely repeatable part and the rewards). Public Event Points contribute towards the completion of Regional Quest objectives, which in turn rewards a number of Energy of Justice commensurate with your amount of participation in the Regional event.
