Rina and her Little Helper

Rina (prontera 201, 295) has been put under a strange curse.
In order to break it, she needs you to do an Oath-taking Ceremony. Once you do that, she asks you kill 50 of one of the following monsters:

• 50 Deviruchi

or

• 50 Wraith Dead

or

• 50 Dullahan

or

• 50 Nightmare Terror

Once you return after killing them, Rina tells you that it's still not enough to break the curse. You will need to find strange marks near the entrance of a city.
Rina will play a BGM for you, and that will tell you which city you need to go to.

Tip: Hover your mouse over the areas near the entry portals to your city in order to find the marks.

Example of strange marks in Lutie:

Go back to Rina and you will receive EXP and a Costume: Egg Crispinette or an Easter Egg Shell.
She will now give stat buffs every time you talk to her.

Rina's Little Scammer Helper
After doing the Oath-taking Ceremony you will be able to speak to the egg next to Rina.
For the price of 400,000z, 1 Egg and 20 Light Granule you can get either a rare Cute Pet Egg, a headgear, or just...junk.
