Mesos, Maple Story mesos

Level 41-50 Priest Quests: At level 50 you gain access to a Priest only quest called Cenarion Aid. The quest starts a 4 part quest chain and will likely take a little Mesos while to complete, I didn't complete the chain until level 54.

The quest becomes available from your priest trainer as soon as you hit level 50. He will let you know that the Cenarion circle is need of aid and that you should seek out Ogtinc in Azshara. Ogtinc is located northeast of the ruins of Eldarath at location 42.

When you reach him he asks that you find 4 healthy courser glands for him and return. These are fairly easy to find off of the wandering courses in the zone.

He will now ask that you find him ichors of un-death and let you know that they can be found by killing the undead in the Ruins of Eldarath. It is also easy enough to buy one from the auction house before you come to get the second quest of the chain. They drop fairly often though so it isn't a big deal to have to farm for one.
