: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)

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%.

Monetary Cost Listed working off Gems cost $99.99 US for 10,000. A 30x Summons costs $83.99 US.

Occurence 1x 10x 30x 100x 500x 1500x
US$ Cost of Summons Cost $3.49 $30 $84 $282 $1428 $7139
Any Season 4 (S4) Hero 67.6% 100.0% 100.0% 100.0% 100.0% 100.0%
Any Season 1 Hero 32.4% 98.0% 100.0% 100.0% 100.0% 100.0%
Any S4 5* Hero 1.6% 14.9% 38.4% 80.1% 100.0% 100.0%

Any S4 3* 51.4% 99.9% 100.0% 100.0% 100.0% 100.0%

Putting That in Perspective

Gems cost $99.99 US for 10,000. A 30x Summons costs $83.99 US.

  • If 1 million players each spent $30 USD & did 10 Summons, 497,884 of those players would NOT get a Season IV or Season 1 5* Hero

  • If 1 million players each spent $281.97 USD & did 100 Summons, 366,033 of those players would NOT get any Featured Season IV 5* Hero

  • If 1 million players each spent $1,427.86 USD & did 500 Summons, 188,351 of those players would NOT get a SPECIFIC Featured Season IV 5* Hero

  • If 1 million players each spent $4,199.58 USD & did 1,500 Summons, 49,638 of those players would NOT get a SPECIFIC Non-Featured Season IV 5* Hero

:dizzy: Bonus Ascension Material Chest


Much like the Season II (Atlantis) and Season III (Valhalla) Summon Portals, The Season IV “Underwild” Portal features a Bonus Ascension Material Chest, which contains a guaranteed Rare or Epic Ascension Material, and can also contain Rare and Epic Crafting Materials.

Also, like Atlantis/ Valhalla, the Bonus Chest fills with each 10 Summons, and there is a limit of 9 Chests per event.

Your progress towards the next chest also carries over to the next Underwild Summon event if you still have chests in stock, just like with the Atlantis / Valhalla Summon.

:gem: Summon Costs

The Summon Costs for the Underwild Portal match the Atlantis & Valhalla Portals:

  • Single Summon: 100 Underwild Coins or 350 Gems
  • Summon x10: 3000 Gems
  • Summon x30: 8400 Gems

:hammer: Underwild Coins

The first time a Stage is completed, a reward is given in Underwild Coins — which are just like Atlantis/ Valhalla Coins, but for Season 4.

Just the same as Season 2 & 3, Normal Mode Stages reward 3 Underwild Coins, and Hard Mode Stages reward 5 Underwild Coins — and there are 10 Stages per Province, so it’ll be the same 80 Coins per Province that Season 2 & 3 had.

Also like Atlantis/ Valhalla Coins, 100 Underwild Coins are required for a free Underwild Summon.

I already own Lepiota and Lidenbrock, so it was a bit risky. But I tried with the offer, and made 2 X 10 pulls. No regret. :smiley:


Yesssssssssss!! :heart_eyes::heart_eyes: Russula on 30 summons ! She looks very cool!


Coin Pull x10 = Russula + Dupe Yang Mai
Gem 10-Pull = Dupe Phileas Fog

Hoped for Lepi or Lidenbrock but no complaints here. :grin:


Rubbish, utter rubbish.


Did first 20pulls and so far all trash.
I want professor but wouldn’t mind Lepiota.
I’m thinking about 30pull but it’s a bit risky…

Managed to scrape 100 coins, thought why not as I liked the highlighted heroes! First 5* from S4 after only having Helena on this account so far.


Two coin pulls…



It could’ve been worse. Could’ve been two S1 3*. :sweat_smile:


Happy for you @leejow! :+1::grinning_face_with_smiling_eyes::grinning_face_with_smiling_eyes::grinning_face_with_smiling_eyes:

Now please share some of your luck with me. :sweat_smile:

me giving hearts to everyone who pulled 5* heroes: :+1: :+1: :+1: ( :sob: :sob: :sob: :sob:)


I would very much like Lidenbrock, and obviously wouldn’t say no to the other featured heroes, but the main objective was to get Yang Mai before it’s too late. Fortunately I got her after - I’ve forgotten how many already - about 8 coin pulls? - and decided to stop there. The 5* will still be in there next month and the month after, along with a few more goodies no doubt. I would have been tempted to make a big fat gem pull if she hadn’t turned up with coins, but now the gems can be blown at the ninja troop portal instead. I have to make up for accidentally eating my holy ninja troop by mistake recently :cry: :cry: :cry:


2 coin pulls, aiming to get S1 3*s for the PoV daily challenge gaining XP…
very dissapointed with a Kelile then a Grifin with a side serving of Yang Mai :smiley:
My 2nd ever HoTM after a 15 month dry spell!


Pulled her this time around. I’m satisfied


Just another money grab scam and an outright lie. 1% chance for featured 5* is better odds? 0.6% for non-featured is better odds?

Pure BS. Bite me. Not spending a penny.

2 coin pulls. An S1 3* and and S1 4*. Trash.

Usually do token pulls then a 10 pull but did it the other way round this time, only got HOTM (my first) in the 10 pull then got Russula in a token pull after🤣
