To start you adventure you have to download the Harry Potter app on your device and make a Harry Potter account. After logging in you will be asked several questions to determine your personality and thus you will be asigned to one of the Hogawart’s houses. This is where your journey begins. After a few first steps Ollivander will give you few wands to test. You’ll have to pick them up and wave them few times. When you find the proper wand it will make a connection with you so you will be able to use it when needed.
After this short introduction you will be able to do whatever you want. Probably the best way to start is to go on a search for few spell tomes or magic creatures. You will even be able to search for Horcruxes however this would be unwise and is strongly reccomended against. The Horcruxes may be guarded by the forces of evil and the contact with Deatheater or Dementor isn’t exatly the best thing for a begginer.
Good idea for a new player is to team up with friends. It’s always better to go in groups for both you and your in-game character. When you are ready to go make sure to use a magic compass located in the bottom right of you screen. It will inform you about nearby points of interest such as spell tomes or magic cards.
Another useful tool to keep an eye on is the Marauder’s Map. It will tell you about an area surrounding you, reducing your chances of getting lost. A pretty useful tool, since your sefety is the number one priority. Just remember to say „I solemnly swear that I’m up to no good” oherwise it may not work.
