skipped most of the thread but most missions involved with the expansions is prolly gonna be easy at 99, wotg may be a bit of a challenge due to some of the missions at the end werent added until after some level cap raises. I feel like alot of people havent really completed wotg tho as they have all the other expansions.
Also keep in mind if you sell a magic scroll from a one time quest and you need it later on for yourself you are at the mercy of what the market wants for it at that time. So take caution. or they may give the spell to another job and the price will soar like phalanx did when pld recieved it
