Fortresses in Wizards Unite: A Crash Course

Wizards Unite Fortress Illustration

In Harry Potter: Wizards Unite, Fortresses can be one of the best ways of gaining XP, an opportunity to place new stickers in the Registry, and overall a fun challenge for players of all levels.  But to new players, it can be confusing as to how to challenge a Fortress and complete the Wizarding Challenges that lie inside.  For that reason, we’ve compiled a crash course to help new players best understand the wonderful world of Fortress Challenges!

For a quick visual overview, watch our editor’s first-ever Fortress Challenge!


What is a Fortress?  Where do I find one?

A Fortress is a structure much taller than an Inn that offers players the opportunity to test their might against various foes in Wizarding Challenges.  Inside Fortresses, players can find Oddities, such as Werewolves and Pixies, along with other Foes, such as Dark Wizards and Acromantulas.

Fortresses are easy to pick out on the map due to their imposing presence.  Much like an Inn, when a player approaches a Fortress, the Fortress will grow in size, signaling that one is in range to complete a Challenge.

How do I start a Wizarding Challenge?

Once a player is within range of a Fortress, they should click on the Fortress to enter it.  If the player has never entered the Fortress before, the option “Ruins Level I” will pop up. After a player clears the previous level, the next level becomes available, though previous levels can still be challenged.  Levels do increase dramatically in difficulty as they go up, so one should be aware of what their capabilities are before entering a high-level Challenge. At higher levels, multiple players are needed to defeat all the Foes.

Once a level has been selected, a menu will pop up, displaying all the Runestones in a player’s inventory.

In order to enter the Fortress and complete the Challenge, a player must pay one Runestone of any kind.  Runestones determine the amount of Challenge XP gained, along with what additional fragments will be dropped, if any.  In Challenges with multiple players, each player must submit a Runestone, though they do not have to be the same.

After all participants have selected Runestones, they will enter a queue, and a countdown will begin.  The higher the level of the Challenge, the longer the queue will take.  Alongside the start countdown is a number portraying the level of difficulty the Fortress has.  Higher chambers will have much greater difficulty.

How do I challenge Foes?

Once the countdown reaches zero, players will enter the Fortress chamber they have chosen.  A timer will start, reflecting the amount of time the players have to complete the Challenge.  Additionally, a symbol of a red skull with a ring around it will display a fraction of the number of Foes remaining over the number of Foes in the chamber.

Foes will appear at different spots on the screen, displaying a level and a number of stars reflecting their strength.  A player’s ability against a Foe is also determined by their Profession.  For more information on Fortress Foes, check out this guide by Mr. T.

To challenge a Foe, simply click on the Foe and click “start.”  While players can initiate combat in this way, it’s important to note that they also have the ability to cast spells beforehand as well using Focus.  It’s also important to note that in Challenges with multiple players, only one player can engage a Foe at a time.

What is Focus?  How do I get it?  How do I use it?

Focus is a quantity obtained both at the beginning and in the middle of Fortress battles.  A player’s starting Focus points are determined by their Initial Focus stat from their skill tree. The player’s profession skill tree also determines the maximum amount of Focus a player can have at any given time.

Players may use Focus to cast spells to help their teammates or to harm Foes ahead of a battle.  Each spell has a different Focus cost, and some spells, such as the Professor’s Mending Charm, do not require any Focus to cast.

A player can check their Focus by looking at the bar on the bottom of their screen in the Fortress chamber, but they cannot use or see their Focus while in combat with a Foe.

Focus is also gained after a player or their teammate defeats a Foe in the Fortress, giving players the opportunity to cast spells on Foes before entering their next battle.

To cast a spell using Focus, a player must drag the icon of the spell they wish to cast onto the Foe or teammate they wish to apply it to.  For Foes, aim for the row of boxes beneath the level indicator.

Now I’m fighting a Foe–help, what do I do?

Once you’ve entered into combat with a Foe, the real work begins.  In order to defeat a Foe, a player must deal enough damage with their spells to get rid of all of its hit points. To explain this, let’s act as if a player is facing this common Death Eater.

The circle on the Death Eater’s knee is the player’s target for the spell.  In order to cast their spell against the Foe, the player must drag their finger on the screen in order to line up their wand’s circle with the target.  Once aligned, the wand will show a second blue circle, reflecting the amount of time it must be held in place before the spell can be cast.

If the yellow circle shrinks fully before the wand’s blue circle is complete, the Death Eater will attack.  But if the player is quick and assures that circle is lined up, they will have the opportunity to attack.

Attacking a Foe takes one Spell Energy per cast and is exactly the same as casting a spell on a Trace or at an Inn.  Once the spell is complete, the Foe will take damage equal to the player’s power and modified by any Potions or Affinities in effect.

After the player has attacked, the Foe will strike back, giving the player the opportunity to cast Protego.  If Protego is cast, which can be done by drawing a diagonal line across the screen, the player will take reduced damage.

This process will continue until either the player’s or the Foe’s hit points reach zero.  If the Foe is out of hit points, then the player will be transported back to the Fortress chamber and will be able to face the next Foe of their choosing.

I’ve been knocked out–what now?

If a player is knocked out in a Fortress battle, they will have to wait around thirty seconds before re-entering the chamber unless aided by the Magizoologist’s Revive Charm.

While knocked out, the player is not able to cast spells or fight.  Once the timer reaches zero, however, they will be able to re-enter the Chamber with full health and whatever Focus they had, and they may face the Foe of their choosing.

Being knocked out in a low-level Fortress chamber isn’t a terribly big deal, though the time penalty can be quite grave at higher levels when Foes take longer.  For that reason, it’s important to have a revive-capable Magizoologist on your team in high-level chambers or to plan methods of staying alive to avoid the time deficit.

What else can I do to be successful in Fortresses?

One great way to help a player’s success in a Fortress is Potions.  To use a Potion in a Challenge, click on the bottle icon in the bottom right corner of the screen either during or in between fights.  Here’s a brief run-through of the Potions available for use, along with what they do:

  • Exstimulo Potions: The Exstimulo Potion, Strong Exstimulo Potion, and Potent Exstimulo Potion can all be used in Challenges to increase a player’s power against Foes. Just as with Traces, these potions last for three, four, and five spell casts, respectively.
  • Healing Potion: These potions can be used during or in between battles to restore a player’s health by 35% of the maximum.  Be sure to stock up on these, as they’re essential to solo success.
  • Invigoration Draughts: The Invigoration Draught and Strong Invigoration Draught increase a player’s Focus when used in between battles, giving players the opportunity to cast extra spells before re-entering combat.
  • Wit-Sharpening Potion: Wit-Sharpening Potions are a huge difference-maker in combat against powerful Elite Foes, increasing damage by 50%.  While not particularly useful in lower chambers that have few Elites, and only available to those above level 15, these potions are important to challengers in the upper chambers.

Besides using Potions, it’s important for players to evaluate their skill tree and decide what’s most important to their success.  The power, defense, accuracy, and other stats gained and improved through the skill tree truly make a difference in Challenge combat.  Players looking to improve their efficiency or strength in Challenges should think about how to best budget their scrolls.

Finally, a great way to improve your success rate in Fortresses is to find some other players in the area to team up with!  Working with others will increase your strength exponentially.

Thank you for this guide. I was most interested in how the runestone-level and the fortress-level play together. Sadly, this stays unanswered. What exactly does a higher level runestone do and what impact do the different fortress levels have on my reward?

I typed Fortress in the search icon.

Hope it helps!
