From Gachapon, and certain Zipangu monsters in Maplestory, there are also cursed 30% and 70% scrolls available. These give the same benefits as 10% and 60% scrolls, except they may destroy the weapon in the process (50% chance if the scroll fails). These are typically only recommended on the first slot. All items can be scrolled, even pet equipments. If you are a warrior, thief, or archer, weapon attack affects damage the most, usually 3 or 4 times more effective than increasing the primary stat.
Mages should focus on getting intelligence on their items (Mesos), usually on the earrings. 60% Jump scrolls on shoes are recommended for warriors, thieves, and archers, while if you go with 100%s, speed on shoes works out better. For rich and funded level 50s, you may attempt to use the Legendary Spirit skill to scroll your level (MapleStory Mesos) 60 weapons, because they are the first weapons to only be available from gachapon and monsters.
