Harry Potter: Wizards Unite - Wizarding Challenge Tips & Tricks
Make sure you manage your ingredient inventory
You only have a certain amount of room for all your potion ingredients — 200 is maximum capacity — and if you're full you won't be able to pick any up from the map or receive any as rewards. This means you could be missing out on some rarer ingredients.
Make sure you are not filling your vault up with common ingredients. You can delete ingredients easily enough and you can always buy more space for 425 Gold, though Gold costs real money so proceed with caution.
Which ingredients are worth saving in Harry Potter: Wizards Unite
Start off with lower level Runestones
The farther you go in the Fortresses, the tougher the foes will be in the Wizarding Challenges. If you feel that enemies are too difficult for you, then try a lower-level runestone. You'll still get the rewards for the type of runestone that you use, but the lower level ones won't be as difficult to overcome. If you're with high level friends, then use a higher level runestone to reap maximum rewards.
Get those red books
Wizarding Challenges are the main way to obtain Red Books, which you need to upgrade your profession's skills. In some ways, they're more important than Restricted Books, which are easy to come by just by participating in events. But Red Books can only be obtained by Challenges, and sometimes you'll get them as daily log in rewards, so make sure you're doing Challenges. It benefits you to upgrade those skills.
Constantly upgrade your skills
As soon as you see the red dot on your Profession tab, you should look into what skills you can level up. The more you upgrade your skills and abilities, the easier Challenges become. No foe shall stand before you once you max out your profession's tree.
Use your gold key on 2KM Portmanteaus
A portmanteau is Wizards Unite version of an egg in Pokémon Go. You walk around with them until they are ready to open. Inside, you will be transported to a famous location from the Harry Potter world and given the task of gathering Wrackspurts for rewards. These Portmanteaus come in 2KM, 5KM, 10KM, and sometimes special 7KM versions, and each one requires a key to open.
You get one gold key to use on your Portmanteaus and that gold key lasts forever, unlike silver keys, which are single use. Try to use your gold key on 2KM Portmanteau's to maximize its use. Save your Silver keys (which you earn by leveling up) to open 5KM or 10KM Portmanteaus. Obviously, the more Portmanteaus you can open with it in the shortest time, the better.
Stockpile your Portkeys and use a Baruffio's Brain Elixir to maximize XP
The Baruffio's Brain Elixir in Wizards Unite is incredibly helpful as it gives you double Wizarding XP from Traces, Wizarding Challenges, and Portkeys. Any time you open a Portkey you should try to do it in conjunction with a Baruffio's Brain Elixir.
Lory, the EIC of this fine site, has another idea to make the Brain Elixir even more potent: "Set multiple Portmanteaus to unlock at the same time, so the brain elixir gives extra XP for all." To do this Lory recommends staggering the timing of when you put the key in the Portmanteau.
Here's an example: You have a 10KM Portmanteau, a 5KM one, and a 2KM one. You want to put a key in the 10KM one then walk it for 5KM. Once you reach the 5KM mark you should put the key in the 5KM portmanteau. Now the two will be ready at the same time. When both of them reach the 8 km mark put your gold key in the 2KM Portmanteau and you will have three ready to go in just 2 km.
Once they are all ready to go you can drink your Baruffio's Brain Elixir and unlock them, gaining the double XP for all three of them at the same time. Really, all it takes is a little forward planning and you can really maximize your Portmanteaus.
Alternatively, you can also just stockpile Portkeys until you have the maximum amount — eight — and then drink a Baruffio's Brain Elixir to get a load of XP at once!
