As with every game, it takes a day or two to learn. I will help people in-game know how to play, etc. NPCs are there to help, not just annoy. The NPC Tobias is the first step, which leads you to class changing. When you change your class, by that time you should know how to play basically. The thing you meet (unnamed
) will explain the basic task of standing up for yourself against the enemies.
Items are received via Quests, or purchased, or even traded (not in Demo 1). Enemies drop items also, but not always rare.
Talk to tobias, and you will be fine. Gooooo Tobias!
