Lets learn how to make the Loyal Servant of Devil Morocc Costume!
First off where is the start of the quest?
We head to the city of Prontera (@go 0)
Walk straight north (towards the castle), and right before entering the castle make a right along the road so you end up going north east Prontera.
Once you reach the top right corner of the map you will see a church. Enter the church
After you enter the church walk until you enter the alter.
You will see Bishop Samuel off on the side.
He will be wearing a White and Gold robe, with brown/graying hair, and a short stature
Talk with him, and he will ask you to bring him a few items to make an elixer to dispell evil spirits from a body.
Get the required items, and then head to Morty, who is in the middle of the field directly south of the town of Morroc (@go 1)
He will be laying on the ground along the south shore of the lake.
Give him the elixer,
If it works, then great you get the item!
If it does not, then head back to bishop Samuel to make another more powerful elixer, but with fewer items required.
Once you give Morty the more powerful elixer, then you should be able to dispell the spirits to gain the Costume!
