It is important to know what weapon is right for your new class because the game does not do a very good job of explaining it. It is very easy to choose a weapon. It is not the end of the world if you choose the wrong weapon, but it can make 4story Luna more than they should be.
Warriors come standard equipped with a sword at level one, and then as they level they gain access to a shield. If you do not have the good luck of a shield dropping for you, then you should buy one from the armor vendor in your main starter city. Having a shield for its defensive bonuses and its special abilities makes moving through the early levels that much easier. Not utilizing the shields abilities will force you to stop to heal every mob or two, while using it will let you keep going and going. Warriors at level 10 can choose to become either Templars or Gladiators.
To start crafting, head close to a sewing machine, double left click the machine, select your work order. At the bottom right corner you will be able to set the quantity of items you want to craft. Alternatively you can press the craft all button, which will craft as many items you can craft with the quantity of mats you have in your cube. You can either switch to this one or repeat the free 1P work order until you reach 40P. At 40P the 1P work order will no longer be available so you will need to start buying work order supplies at that point.
