Try not using those damn abbreviations, we don't want to guess what you wrote over there.
The Cursed Palace is in Athens. Every Sunday there's a time period, in which you must pay 1/2 registration vouchers for entering. There, you must fight all 12 zodiac signs, and the 13th fight is against Athena and some strong mobs.
After you won all battles, Athena will reward you. Rewards are:
-Thorn rings
-Dragon Wing Spear
-Shining Bow
-Moon wand
I think these are all rewards.
