:gem: Summons Costs

Like all other Event Summon Portals, the Portal Cost is per below:

Single Summon

  • 10 Challenge Coins
  • 300 Gems

10x Summon

  • 2600 Gems

:game_die: Summoning Appearance Rates

Please note that Challenge Event Heroes are amongst the lowest odds of any Hero in the game. Even with a large number of Summons, you are very likely not to get Challenge Event Heroes, particularly 5*.

I highly recommend setting and sticking to a budget for Summoning to avoid overspending and frustration.

Rare Classic Hero: 63.1%
Epic Classic Hero: 20.8%
Legendary Classic Hero: 1.5%

Rare Event Hero: 7.9%
Epic Event Hero: 5.7%
Legendary Event Hero 1.0%

Legendary Hero of the Month: 1.3%

:money_with_wings: Analysis of Summon Appearance Rates

This table shows the cumulative probability of different Summon events, based on a total number of Summons (1x, 10x, 30x, 100x, 500x, 1500x). Based on 10,000 gems costing 99.99 USD, I have also added an approximate $ cost too.

Please note that NO occurrence is ever actually 100%; the 100% entries in the table below indicate cumulative probabilities sufficiently close to 100% that they are expressed as such for simplicity. All other numbers are rounded to the nearest 0.1%.

Occurence 1x
Get at Least 1 Avalon Hero (3*-5*) 14.6% 79.4% 99.1% 100% 100% 100%
Get at Least 1 of Any 5* Avalon Hero 1.0% 9.6% 26.0% 63.4% 99.3% 100%
Get at Least 1 Particular 5* Avalon Hero 0.2% 2.0% 5.8% 18.1% 63.2% 95.0%
Get at Least 1 of Any 4* Avalon Hero 5.7% 44.4% 82.8% 99.7% 100% 100%
Get at Least 1 Particular 4* Avalon Hero 2.85% 25.1% 58.0% 94.5% 100% 100%
Get at Least 1 3* Avalon Hero 7.9% 56.1% 91.5% 99.9% 100% 100%

Putting That In Perspective

  • If 1 million players each spent US$26.00 to do 10 Summons, 206,000 of those players would NOT get ANY Avalon Heroes

  • If 1 million players each spent US$259.97 to do 100 Summons, 366,000 of those players would NOT get ANY Avalon 5* Heroes

  • If 1 million players each spent US$1,299.87 to do 500 Summons, 368,000 of those players would NOT get a particular Avalon 5* Hero

Me too! I don’t have any avalon heroes so gonna spend my few challenge coins and hoping for Bauchan :slightly_smiling_face: he’s the only one I’d actually be able to level in a reasonable amount of time anyhow :rofl:


For Many a Year Guin was the Only Hero I REALLY wanted… No more lol…

May I please have me 1 lil BK??

Thank you in advance :hugs:


I got 2. I’ll sell you one for the low price if tree fiddy.



Can I pay with 4*AM’s ?

I will even throw in a Couple o Backpacks :thinking:

Naw I need more dawas. You can never have too many of those bad boys.

Poor King Arthur isn’t even relevant enough to be on the poster. :stuck_out_tongue: That’s Frida for you.


Tell me about it. I got Arthur last year and he’s just sat in my roster at 1.1 ever since. Whenever I feel like dusting him off another nice blue catches my eye instead. Anyway an armoured polar bear with a mace is miles cooler than a mere human king with a weird beard.

I also got the glorious Black Knight at the same time. Needless to say he went straight up to 4.80 as fast as ever I could level him, and he’s been a fixture in raid and war defence ever since, as well as guest appearances in some raids and events.

This is my equal best portal (with Teltoc), in fact, as it’s given me all of them except Guinevere (can survive without) and LotL (would love). Morgan has been parked at 3.70 more or less forever, and although I maxed Lancelot I kind of forget he exists when putting 4* teams together, but Merlin and Bauchan are great.


Bump because took me way too long to search the thread

Just frustrating if you summon two 5* heroes at Avalon, but both are S1…


After a long drought in Valhalla Pull, I got King Arthur with 5 coin pulls. I don’t have Frida, so I plan to level him for the 12* Titan.


Pulls? What pulls? Oh you mean the crap S1 3* dupes I got from coins? Nah let’s not even talk about them. 10x gem pull did gave Bauchan, Merlin, and Lancelot all in one go tho, if I didn’t any better I’d have thunk this was some kind of SG conspiracy to force us to use gems! Oh wait… :thinking::crazy_face:

Btw finished rare with this:

Kvasir does two things here:

  • prevents LotL from spamming her damn sword minions
  • maximizes cBrienne’s debuff since each minion hit counts as a “hit” for debuff purposes

Went into boss round with everybody charged and 3 minions on each hero and a green diamond ready to be assembled. Let’s just say the results were nothing short of glorious. Yellow tiles did stupid amounts of damage, and when all was said and done, LotL was gone, Arthur was half dead, and Guin in critical health. Finished them off with an axe and that was that.


Great, another challenge with thrash rewards if you aren’t top 1%… And those summon odds, never seen numbers so low for special heroes :confused:

Thanks for the info, I just finished cBrienne because of that def down. Didn’t think of using Kvasir to bring it down even further! Sounds look a great combo indeed but I haven’t started Kvasir yet. Looks like I’m gonna have to speed things up :smiley:


10 x Summon… 10 x 3* - 2 Of em Bauchan… No HOTM lol…
