Catacombs Skeleton Key Boss

Wizard101 has brought a new update for Spring 2020, which added a new boss – The Fellspawn! According to druidic lore, it’s “a survivor of the destruction of the First World.” Others even believe it to be a myth, a mere legend dreamt up by the druids to scare their children. Well, I can tell you that the Fellspawn isn’t a legend – it’s real. It also drops some pretty insane things, such as the current top tier Dragoon’s gear (this is the only current direct drop source for Dragoon’s gear). As the new set bonuses are applicable to the Dragoon’s sets as well, players should definitely consider taking a look at this guy.

The Fellspawn Battle

Now no reward in Wizard101 is without challenges, and this instance is certainly no exception to that rule. It’s worth noting that the boss can pull you in from a pretty insane distance, so make sure your entire team is ready! You also need a team of four wizards. Should you have less than that, Fellspawn will start summoning his own minions on your side of the duel circle! However, it’s worth noting that any minions he spawns on your side of the duel circle can be sacrificed with spells like “Sap Power” or “Sap Health”.

The boss starts with 57,500 health, and is Storm/Shadow school. At the start of the first round, he’ll interrupt cast a bubble that caps damage at 9,999, similar to that of Empyrea’s Titan’s Trident, which cannot be changed. This bubble will also limit DOT spells to 3,333 damage per tic. After that, he will proceed to summon 3 minions (more if you don’t have a full team). These minions can be of any school, and range from 6,900 to 8,800 health. However, once killed, they are respawned one at a time every third turn. If a wizard joins or rejoins after the second turn, The Fellspawn will interrupt cast a shadow version of Call of Khrulhu dealing 830 damage to all.

In the storm form, The Fellspawn resists  storm for about 70%. He resists Fire, Ice, Balance, and Death for 25%. Life and Myth do boost on it, but for merely 5%. In Moon Phase, he has no boosts or resists. In both forms, he has an outgoing damage boost of about 120%, and a pierce of about 35%. 

Enemy Cheats

The cheats for this boss depend on which form it’s in: Storm or Moon. Fellspawn’s forms are similar to that of Barkingham’s Dr Jekyll and Waterworks’ Sylster Glowstorm. At the start of every fourth turn, the Fellspawn changes phases. Fellspawn will always start in its storm/shadow normal-sized self. The other phase is a giant sized Moon school version.

Storm Phase

While Fellspawn is in the storm phase, players cannot blade. Should you blade, it will immediately cast a mana burn on the caster of the blade, for about 600 shadow damage per pip, removing 2 pips from the unfortunate wizard. In addition to that, he casts a enfeeble on the receiver of the blade. Other than that, he doesn’t really have any cheats. Therefore, you should definitely trap and prism him during this phase. For any jades on the team, you can also cast plagues, jujus, and any other negative debuffs at this time.

Moon Phase

In the giant-sized moon phase, players cannot apply any negative wards on the Fellspawn. Should you accidentally do that, it will apply a cleanse to every trap on itself. On top of that, the caster of the spell will be stunned for two turns. Also, Indemnity-enchanted wards will not be removed the first time, and the stun can be resisted or shielded. It is also important to note that he does not remove preexisting traps when he transforms. On top of that, upon changing into the Moon phase, the boss will cast a black mantle on a random player, a weakness on a random player, a tower shield on itself and each of its minions, as well as a bladestorm. It will do this whenever it is hit as well.

For defeating Fellspawn, wizards have the chance to get the Dragoon’s sets, as well as the Vanguard’s sets of gear. In addition to that,  after defeating this boss multiple times or following certain difficult conditions, wizards can earn rare badges to commemorate this tricky achievement.

In Conclusion…

This living legend is honestly pretty straightforward! My personal recommendation is to have two tanks, someone to deal with the minions, and someone to deal with the boss. Ideally, having a death tank is handy, because they can apply juju and plague without any problems. My perfect team would have to be Life, Death, Storm, and Myth. Theurgists can apply heals for the heavy hits that this boss carries, Necromancers allow for damage control, Diviners melt the minions, and Myth can take on the boss with DOTs as well as heavy hits.

Dakota's been playing Wizard101 for well over ten years now. He's seen a lot of change in the game, and loves to check everything out on his trusty Storm and Death. When an update comes out, expect to see him running around to create strategies and discover secrets. While he's more of a PvE player, Dakota isn't new to PvP, formerly a tournament PvPer. Nowadays, he spends his days playing Beastmoon and working on his fire wizard.


  • I just hit Fellspawn with a dark nova in his storm phase and he resisted Shadow damage. I would add that to the guide.

    • He also boosts to Myth in storm form.

    • I’ll add it in! Thank you!

  • Can someone confirm – does he resist fire in his storm phase or not? Some people tell me he does, some people tell me he doesn’t. Videos and wiki says he doesn’t, this article says he doesn’t, but it’s old so idk how up to date everything is. Today I was testing out a 5 round strategy (success) and before we started I went in to test if he has resist so that I can work on the 3 round strategy. I used 2 fire WAND attacks and I saw “resist” yet I somehow did 4000 damage on him…It must have been a bug or something so I’m not sure. Does he resist fire in his storm phase or does he not?

  • does anyone know what the badges are, any of them will suffice

    • I know of 4.

      Fellspawn Striker
      Fellspawn Foe
      Fellspawn Adversary
      Fellspawn’s Nightmare

      • Any idea what the criteria are for earning any of the badges?

        • Fellspawn Foe is for beating him for the 1st time
          Another 1 (not sure which) is for beating him in 3 rounds
          And I heard a rumor that there’s a badge for beating him 100 times, which leaves the 4th badge to be beating him 10 times (which is pretty lame, imo)
          Not sure about the beat him 100 and 10 times, but certain for the other 2, if someone can confirm, please do so.

          • Also, I have 18/23 badges for the key bosses and have only 1 (Fellspawn Foe) for Fellspawn, which means there r 2 more alongside the other 4 as well, making 6 total badges for Fellspawn. For those, I have no clue thou.

          • Fellspawn Foe is not just for beating him the first time. I had a wizard beat him 13 times with NO Badge whatsoever. It was only when I was in the first position (sun) and got in the kill shot that I finally got the foe badge on my 14th battle.

            I also got the fellspawn nightmare badge the same battle. Not sure what I did to get it.

            I heard that the 6th badge (I think it was fellspawn bane) was for getting all the other 5 badges.

          • Fellspawn Foe should be for killing him the first time. It has to be a bug that you get it only when you’re in first position. I got it on my 2nd try and my friend got it on their first try because they were first. That makes absolutely no sense so it has to be a bug.

            And yeah, getting a badge for getting the other 5 badges makes sense, prolly is that.

  • Myth knows Keeper of the Flame
    Balance knows Availing Hands

  • Myth knows earthquake now

  • Think this a glitch but a pet bubble works and he won’t cheat to remove it

    • That’s correct

    • Not any more, they patched the glitch.

  • This article is very useful! I don’t know when I will plan on doing it, nor how I will. I was interested in this boss, and decided to look at the cheats. Cause why not, right? I will most likely do this on my Life Wizard, Alexandra Song. I feel better healing than hitting. Again, this article is very useful. Thanks so much for posting this! 😀

  • The life tentacular horror can also use rebirth. Awesome article though!

  • Apparently, if there isn’t a full group, Fellspawn has the chance to summon an “Unhelpful Spawn” minion to your side.

    • Happened to me today, it will spam that minion very frequently. It will be very annoying and can only be hit by the boss and minion tentacles, so only can be defeated by them

  • Very nice article. I did fell spawn with in minutes after the test realm started and everything in here is described perfectly.
