With a better speed, spears and pole arms, swords have the most reliable damage of we think any weapon in the game(MapleStory powerlevling). All of these weapons are slower then swords making for faster kills, and. This makes most Crusaders both faster and stronger then other classes. You will need to be a very high level although they do have elements, like 90+, to have all elements maxed out.
Pages have the ability to attack with Fire, Ice, and Lightning. This means that if they find themselves in a situation where they are surrounded by monsters weak to fire they can whip out their fire attacks, they can quickly adapt to the change if the situation changes to ice-weak monsters in Maplestory. Plus, ice charge freezes the enemy for a second or two.
They also have Magic Crash which will allow them cancel out Magic Defense. Spearmen can choose to either stick with one weapon(MapleStory gold) or go hybrid, meaning to master both weapons. It's strongly recommended that you stick with one weapon with the exception of Spearmen.
