NO.1 : HEAVEN!
Don't forget to prepare yourself in HUB / HEAVEN before journey. Learn new skill first, sharpen your knife and pack up some bread and wine along with you.
NO.2 : GROCERY STORE
In the Groceries shop, there are some consumable things that will be useful for you. Bread will recover your health and Wine will recover mana. You can use it anytime while battle. Seed will open two way gate teleport you to the Hub and back to that point again if you want. Remember, seed has casting time and it can be cancel if you got attacked.
NO.3 : SET UP GROCERIES ITEM
After shopping groceries, tap the inventory button at the up-right corner to open your bag. Tap & Hold an item to start moving it, drag and release it in the left-side slot, then tap empty space to close the bag. These set up will help you use items so conveniently while battle!
NO.4 : LEARNING/UPGRADING SKILLS
Every class has different set of SIGNATURE SKILLS which can be put into hotkey. You will be able to press it easily while battle. If you learn them, but not set them, you can not use them! NORMAL SKILLS are passive, once you learn them, they effect immediately to your current character.
NO.5 : SETTING SKILLS IN HOTKEY
As I said in the previous tip, you can set signature skills in hotkey. You need to learn it first, tap & hold for a while, and drag it into big empty slot above.
