Swords look cool :p They are 1-handed also(the books too).I REALLY wanna ask why the books stop(what happend with the book:Tears of a Fallen Angel-A grade) at low grades.Maybe because they are all the same at looks?
Yes the "best" is devotion set and one of the top weapons like mage staff or voodoo doll. My suggestion is too late for you since you already have the gear, but on my newb mystic I leveled from 1 to 20 on leather tunic, stockings, and an apprentice book very easily. You don't need top gear to hit 20, unless you don't have any gear ready for 20+
Thats the only reason? Because swords have a low M Atk rating, i would think staffs and books would be the best.
The "mage swords" they're talking about have good MAtk and reduced PAtk, they're just sword-type instead of blunt-type. Most mage weapons are blunts, but they come in swords, daggers, and "etc" as well.
