i dont know about that.
look at this
Max HP +15%, Max SP +20%[ Mage Class ] Int +15, Dex +15[ Archer Class ] Dex +15, Agi +15[ Swordsman Class ] Str +15, Agi +15[ Thief Class ] Str +15, Dex +15[ Taekwon Class ] Str +15, Int +15[ Gunslinger Class ] Dex +15, Agi +15[ Ninja Class ] Int +15, Dex +15[ Merchant Class ] Int +15, Dex +15[ Acolyte Class ] Int +15, Agi +15[ + Forsaken Armor, Cloak, and Shoes ] Immunity to freeze, ASPD +2
Swordsman is also = Pally or LK
and it works on pally.
Thief is a first job like Swordsman
so its not clear enough.
