: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 Fables Hero (3*-5*) 14.6% 79.4% 99.1% 100% 100% 100%
Get at Least 1 of Any 5* Fables Hero 1.0% 9.6% 26.0% 63.4% 99.3% 100%
Get at Least 1 Particular 5* Fables Hero 0.2% 2.0% 5.8% 18.1% 63.2% 95.0%
Get at Least 1 of Any 4* Fables Hero 5.7% 44.4% 82.8% 99.7% 100% 100%
Get at Least 1 Particular 4* Fables Hero 2.85% 25.1% 58.0% 94.5% 100% 100%
Get at Least 1 3* Fables 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 Fables Heroes

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

I think this will work. :slight_smile:

Sure or maybe throw in a cGunnar instead of Belith?

I need a healer instead of Gunnar for health bonus. Thanks!

If you are pushing for the score, you dont really need a healer. If the board is that bad that your heroes are hit multiple times, that is probably not the run for a good score anyway.
I will push for 1k rare using this team:


Rare Completed :slight_smile:


Did 4 x tens … Got a dupe hansel and Gretel. And a millionth frost.

Disappointed but not surprised.


AI on Autoplay is outrageous…hiting tiles and uses heroe that attacks be reflected :poop::poop::poop:

I had just 5 tokens but decided to use them anyway. Result, another Skittles, my first Hansel (what does he do?), yet another Bane, Pixie and the much loved Oberon dupes.


That’s not a serious question, is it? Hansel is the master of mana control (4* version). Treasure him.

Pixie does similar at 3* and is also to be respected.

It totally was, I was just over summons for the last week and kind of didn’t internalise anything after locking his card. :frowning_face:

I love Pixie, she is under rated imo. Having some fun with Shadereave from Valhalla also. A green 4* mana controller? I can get on board with that! Fortunately I have the mats for both of them and some friends atm


Ah, you already know the charm of Pixie, in that case trust me, Hansel will also float your boat :smiley: Emblem him up though, he’s squishy. What a good thing you lock first and ask questions afterwards…!


This is me, building a team for Events for the first time. Since it’s Grimmforest, it’s blue:

First 4 from the left seems to be as good as it can be, just to throw few more emblems there. Jarvur - should I maybe put Gato? I have him, just without emblems. Jarvur is ok for tourneys though. Thoughts?

Troops will come next, too.

My walk through today already is much better than my scores in the past. I guess I would need like 40k to hope for top 1000? :thinking:


Can’t help on tactics for a good score, as I’m usually relieved just to finish above the bottom, but a thought on the Gato question is that, if he is next to Chick and fires first, he should block Chick’s self debuff. Jarvur is probably not best suited to this job, as if he is able to build up a decent number of stacks it means you’re taking far too many moves to score well. But I’m happy to be corrected.


My second 5* from a single pull from a challenge event. Unfortunately, a dupe. :sweat_smile:


I find Gato more useful. He has higher attack stat and hits harder, but most important - placed next to Chick Jr, he prevents his negative attack aliment.
And - gratz on the score! :slightly_smiling_face:


Did my one event 10-Pull and landed Red Hood! Eventually will be part of secondary :fire: team :star_struck:
