1. Welcome to Ardeca! When you start you are given a +9 level one weapon, 5,000,000 Dils (basic currency), as well as health and mana potions and some malakites. To access your inventory, press "I". I suggest moving the potions and malakites to the bars listed F1-F6, this is your item hotbar!
2. You will also receive some higher level gear! Depending on your class you should receive one of each type of weapon, and 5 pieces of armor that make up a set! You will also receive three boxes, an egg, and a key. The key will permanently add a second tab to your Storage Keeper, but can only be used once per account! The egg is a pet. Right click to hatch the egg, and equip it in the pet slot . To summon your pet, press "T", the pet will automatically pick up items for you! Press "Y" to change the item settings that your pet can pick up. Lastly the boxes, each is different. One is the box that all your high level gear was contained in, this you can put into your storage forever! The second box is a Random Item box, open it to receive a random gift! You could get lucky and get an exp amulet! The third box contains a set of beginner wings for lvl 140, you can put this in storage for now! Below is a map with some key points marked out, I suggest you visit one of the storage keepers and drop your higher level gear off! Just right click it in your inventory to move it into the stash inventory.
