Fortress Foes in Wizards Unite

Death Eaters apparate in

The fortress system in Harry Potter: Wizards Unite is a fun challenge for even the most experienced of mobile gamers. With a variety of Foes at multiple levels offering different strengths and weaknesses, you need a solid strategy to win higher-level fortress battles.


Here’s everything you need to know about the fortress Foes in Wizards Unite.

Fortress Foes Affinity: Advantage, Neutral, and Mismatch

Currently in a fortress, players battle against six different types of Foes that belong in three distinct categories:

  • Dark Forces like Death Eaters and Dark Wizards
    • Fortress Icon: Red skull
  • Beasts like Erklings and Spiders (Acromantula)
    • Fortress Icon: Blue claw mark
  • Curiosities like Werewolves and Pixies
    • Fortress Icon: Purple question mark

Depending on your profession, Foes will have a green up-arrow icon, the red minus down-arrow icon, or no icon. Each profession has one proficiency (advantage), one deficiency (mismatch), and one ‘other’ (none, neutral). No single profession is strong versus all three types of Foes.

Bonus Damage: Proficiency means that your profession has an advantage over the Foe, which is added Power (Proficiency Power). Each profession starts with 20% and can get up to 148%/150%. Example: If a Professor has 100% Proficiency Power and attacks a werewolf, then it will do 100% more damage to the werewolf (if it does not have Deficiency Defense). This bonus damage (Proficiency Power) makes a huge difference.

Total Advantage Power (%) = Player’s Proficiency Power – Foe’s Deficiency Defense

  • Auror: Proficient vs. Dark Forces, Neutral vs. Curiosities, and Deficient vs. Beasts
  • Magizoologists: Proficient vs. Beasts, Neutral to Dark Forces, and Deficient vs. Curiosities
  • Professors: Proficient vs. Curiosities, Neutral vs. Beasts, and Deficient vs. Dark Forces
Profession Advantage
Neutral Mismatch
Aurors Dark Forces Curiosities Beasts
Magizoologists Beasts Dark Forces Curiosities
Professors Curiosities Beasts Dark Forces

Foe’s Proficiency and Deficiency

FOES Proficiency Power Deficiency Defense
{Difficulty} All Foes*  All Foes*
Regular 5-10% 0%
Formidable 10-20% 0%
Imposing 15-30% 5-10%
Dangerous 20-40% 7-15%
Fierce 25-50% 12-25%

*First percentage is Common Foe and the second percentage is Elite Foe. The Elite’s stats are around double (2x) the regular’s Proficiency Power and Deficiency Defense stats.

If you are deficient against a Foe (example: Professor vs. a Death Eater), Regular Foes do 5% more damage to you and Fierce Foes do 25% more damage. To counter this bonus damage, players should get Deficiency Defense.

  • All professions can get up to 50% Deficiency Defense to negate any Foe’s Proficiency Power.
  • Foes have a low Deficiency Defense (up to 25%) compared to a player’s possible 148%/150% Proficiency power.

Difficulty of an Encounter in a Fortress

A Foe’s strength or difficulty to face is represented by stars. There are five difficulties for each Foe: Common (1 star), Formidable (2 stars), Imposing (3 stars), Dangerous (4 stars), and Fierce (5 stars).

Each difficulty has two types: Regular (no extra label) and Elite.

Elite Imposing Dark Wizard

“Elite Foes are more challenging variants of the Foes you’ll face. You’ll know if you’ve encountered this unique enemy if their health meter is purple, and the ‘Elite’ title appears before their name (for example, Elite Erkling). Participating in higher difficulty Chambers increases your chances of encountering an Elite Foe” (Source: Niantic Helpshift).
Also, an Elite Foe has a bright golden border around it (see image on the right).

So, there’s 10 different variations for a single type of Foe: e.g. Erkling, Elite Erkling, Formidable Erkling, Elite Formidable Erkling, Imposing Erkling, Elite Imposing Erkling, Dangerous Erkling, Elite Dangerous Erkling, Fierce Erkling, and Elite Fierce Erkling.

An increased difficulty means its stats are increased (Power, Stamina, Proficiency Power, and Deficiency Defense). As of right now, Foes do NOT critical hit, block, or cast strategic spells, so their Precision, Critical Power, Protego Power, Accuracy, and Focus are either 0, 0%, or not valid.

Difficulty: Foe Base Stats

Special thanks to PAndras96 on Reddit for making sense out of the game data.

Every Foe’s Stamina and Power increase linearly by 8.16% each level.

Base (Level 0) Stamina Power vs Regular
vs Previous
Acromantula (‘Regular’) 72 8
Formidable Acromantula 91 10 126%
Imposing Acromantula 109 13 151% 120%
Dangerous Acromantula 136 17 189% 125%
Fierce Acromantula 166 22 231% 122%

Each difficulty level goes up 20-26%. A Formidable Foe (2 stars) has 26% more Stamina and Power than a Regular Foe. The Regular (1 star) to Fierce (5 stars) is a difference of +131%, facing one Fierce Acromantula is equivalent to facing 2.3 Acromantulas.

Common vs. Elite Foes

Elite foes have around 87% more Stamina and Power than Common Foes, which is almost double the difficulty.

For example, a level 50 Elite Acromantula has 685 Stamina and 81 Power
whereas a level 50 Acromantula has 365 Stamina and 40 Power.

The Regular (1 star) to Elite Fierce (5 stars) is a difference of +131% on top of 87%, facing 4.3 Acromantula is like facing one Elite Fierce Acromantula.

Comparing Stats of the Various Foes

Foe (Base Stats) Stamina Power
Acromantula 72 8
Dark Wizard 62 7
Death Eater 83 6
Erkling 76 7
Pixie 41 7
Werewolf 70 7


Foe (Base Stats) Stamina Power
Elite Fierce Acromantula 310 41
Elite Fierce Dark Wizard 211 26
Elite Fierce Death Eater 328 22
Elite Fierce Erkling 258 24
Elite Fierce Pixie 140 43
Elite Fierce Werewolf 296 30

Highest: Death Eaters have the highest Stamina and Acromantula have the highest Power.
Lowest: Pixies have the lowest Stamina and Death Eaters have the lowest Power.

Foes at lvl 50 Stamina Power Stamina vs. Average Power vs. Average Stamina Power
Fierce Acromantula 843 111 120% 141% A A++
Fierce Dark Wizard 574 71 82% 90% C B-/C+
Fierce Death Eater 899 55 128% 70% A+ C-/D+
Fierce Erkling 706 66 101% 84% B C
Fierce Pixie 381 91 54% 115% D– A
Fierce Werewolf 807 81 115% 103% A B
Average 702 79


Grading Scale
Percent vs Average
A 110-130%
B 90-110%
C 70-90%
D 50-70%

Based just on Stamina and Power stats, Acromantulas are the hardest Foe. Dark Wizards are the weakest. However, this does NOT account for Defense, Defense Breach, and Dodge. The two without any of those stats, Acromantula and Death Eaters, are similar in Stamina, but Acromantula have much more Power, double in this scenario (111 vs. 55).

Defense, Defense Breach, and Dodge

FOES Defense Defense Breach Dodge
{Difficulty} Werewolves Dark Wizards Werewolves Dark Wizards Erklings Pixies
Regular 0% 0% 0% 0% 0% 0%
Formidable 5% 5% 0% 0% 5% 5%
Imposing 25% 15% 0% 10% 25% 25%
Dangerous 40% 30% 10% 20% 40% 40%
Fierce 60% 50% 30% 40% 60% 60%
  • Notably: Acromantulas (Spiders) and Death Eaters have 0% Defense, 0% Dodge, and 0% Defense Breach.
  • A Foe’s Defense is countered by Defense Breach
    • Defense Breach: Aurors can get 32% (+30% vs Werewolves), Magizoologists can get 22%, and Professors can get 15%.
  • A Player’s Defense is reduced by a Foe’s Defense Breach
    • Defense: Aurors can get 39%, Magizoologists can get 50% (+21% circumstantially), and Professors can get 44% (+30% Protection Charm and +30% based on impairments and enhancements).
  • A Foe’s dodge is countered by Accuracy (and maybe Precision)
    • Accuracy: Aurors can get 15%, Magizoologists can get 20%, and Professors can get 32% (+30% vs Pixies).
    • Precision: Aurors can get 35% (+35% vs. Foes at full health, +25% vs Death Eaters), Magizoologists can get 20%, and Professors can get 23%.
  • Confusion Hex: An Auror has a Confusion Hex (1 Focus to cast on a Foe), which decreases a Foe’s Defense, Defense Breach, and Dodge up to -60%. The hex is only effective against Werewolves, Dark Wizards, Erklings, and Pixies. At max level, this strategic spell seems to negate all bonus stats (Defense, Defense Breach, and Dodge) of all Foes, even the hardest Foe, an Elite Fierce, because none of those stats goes above 60%.

Summary of Foe Stats


  • Acromantula: Exceptional Stamina and Highest Power
  • Erkling: Average Stamina, but dodging makes it difficult to defeat, and below average Power.

Dark Forces

  • Dark Wizards: Below average Stamina and Power, but Defense and Defense Breach give it added stats. The main counter would be to have more than enough Defense Breach to get through its Defense.
  • Death Eaters: Highest Stamina and Lowest Power, which seems opposite than what you would think.


  • Pixies: Lowest Stamina, but dodging makes it difficult to defeat, and second highest Power.
  • Werewolves: High Stamina and average Power, but Defense and Defense Breach give it added stats.

Overall: Werewolves have very good stats along with Defense and Defense Breach, making them the overall hardest Foe to defeat. Acromantula (spiders) also stand out as a solid Foe even without any bonus stats. Erklings and Pixies are mediocre, but dodging will lead to longer battles and more damage taken. Death Eaters are bulky, but do not hit hard.

Note: To improve your own stats against fortress Foes, you need to fill out your profession’s skill tree. We’ve put together a handy tool that lets you try out different routes for progressing along your skill tree. That way, you can calculate how many scrolls, spell books, and restricted section books you need to earn.

I hope this guide on fortress Foes will help you strategize before your next fortress challenge. While you can’t choose your Foes in a solo battle, you can during a group battle. Selecting advantageous match-ups can make the difference between victory and defeat in a high-level fortress challenge.

Just fyi most, almost all of the chart (info I’m boxes) doesn’t fully show on my phone, I can’t slide over, shrink or turn phone to see all of the information. I feel like I’m missing some of the info, slightly frustrating.

I noticed that the power has not the same percentage increase of stamina in your table. Is it a mistake? I’m not sure about the comparison between common foes and elite fierce foes also: pixies have 43 power. Isn’t it too much? It’s stronger than a werewolf but they both start from power base 7. Why pixie is stronger when its difficulty raise?
