IGG released a new features in the (Sept/Oct 2015) update, which enables Legendary 10 star Heroes to continue getting tougher and gain a new look.

Evolutionary Requirements Overview

Currently only Legendary Heroes can be evolved and although  evolve, their Ico hp.png HP per level does not.

Also Harpy Queen is subject to an anomalous drop in her Ico hp.png HP base.

Before a Hero can be evolved, it must be 10 Stars, which requires it to be Level 180, 9 Stars and needs the following:
  • A minimum of 550 Fire (Dungeon flames)
  • 400,000 HB and 5,000,000 Gold
  1. 1.0 1.1 1.2 The duplicate Hero must be the same type (ie Druid for evolving Druid), can be of any level or a Hero Card of that type (ie Druid for Druid) but not a Legendary Hero Card (LHC) / Specialized Legendary Card (SLHC).

Returned Books from Evolution

Blessed Tome II.png

When a hero is evolved, any experience above the minimum evo level (180 for evo1, 185 for evo2) is returned in Blessed Tome-II Blessed Tome II.png exp books (500k Exp.png per book) with that experience rounded up to the nearest 500k Exp.png.

The following tables shows the minimum number of books that are returned for each level, what level these books can level a new hero to and for each level where the next 500k Exp.png break starts on that level (add 500k steps to this number to find where the subsequent breaks start, ie for 183 the first break is 313,501 Exp.png, so the next break will be at 313,501 + 500,000, the next at 313,501 + 2 x 500,000 etc).

Star Leveling Up Heroes

Honor Badges are also used to increase the Star level of a hero, which raises it's maximum level capacity:

How to work out Evolution DMG and HP from Hero Info Stats:

Use the "Base Evo Stats (Level Up)" shown in a Hero's "Info Box" (found at the top right of each Hero's page) to calculate a Hero's damage (DMG Ico attack.png) and Hit/Health Points (HP Ico hp.png) for a given Hero Level:

Spirit Mage
Base Evo1 Stats (Level Up)
Damge: [669+] 378 (+13)
Hitpoints: [10230+] 1680 (+90)
Evo Base + ( Evo per Star * Stars ) + ( Evo per Level * Level )

Spirit Mage example with Ico attack.png Damage: [669+] 378 (+13) and Ico hp.png Hitpoints:[10230+] 1680 (+90):

Ico attack.png  DMG   = 669 + ( 378 * Stars ) + ( 13 * Level )
Ico hp.png HP  = 10230 + (1680 * Stars ) + ( 90 * Level )
  • Make sure to include the "Evo Base" amount shown in the "[ ... ]"
  • Please note that with the evolution calculations you do not use a level minus one.
  • Ensure to use the star value shown on the hero - first evolution hero's start at 4 stars and second evolution at 5 stars.

Formulas for Calculating a Hero's Evo Stats

Evolved Heroes Star level evolve from level 1 with 3 + evolution generation Stars. This means that the Hero's Stars will not increase until the evolved Hero reaches the relevant level to Star level, ie, level 80 to go above 4 Stars, level 100 to go above 5 Stars.

Evolved Heroes still follow the standard stats formula with these exceptions:

  1. The Hero's HP and DMG now include a base amount (not a standard base stat).
  2. The Hero's Stars start at 3 + evolution generation Starsi.e. first evolution starts at 4 Stars and second evolution starts at 5 Stars.
  3. The Hero's Stars do not start increasing until the hero reaches the relevant level to Star level.
  4. Standard Star leveling will not start until the hero reaches the relevant star level which is 80 for evo1 and 100 for evo2.
  5. Evolved Heroes have their own evolved base level up base stats, but, there are formulas that can use the standard base stats.

This now means that calculating evolved stats includes the Hero's unique fixed base as well as new base stats(be careful not to confuse base with base stats) which is typically shown in [x+] in the Hero's Info Box" and Stars will not start to increase until the Hero reaches 4 or more Stars.

INT( Level * 7.6 + Skill Level * 97.5
+ Talent Level * 20​
+ (MOV SPD-198) * ( Level / 180 )  )

To calculate evo1 hero stats, use the following:

  • Evo1 DMG = EVO1 DMG Base + EVO1 DMG Level Up per Star * Stars + EVO1 DMG Level Up per Level * Level
  • Evo1 HP = EVO1 HP Base + EVO1 HP Level Up per Star * Stars + EVO1 HP Level Up per Level * Level

Comparing Hero First Evolution to its Standard Counterpart:

The evo1 heroes' stats have many advantages over their counterparts including starting out with a massive base making them up to around 3.0x - 1.88x HP and about 1.6x - 1.33x DMG than their counterparts. But this is partially offset by Star leveling up increases not starting until the Hero reaches 5 Stars.

Evo1 HP and Evo1 DMG are larger than its equivalent counterpart but the biggest increase is with HP with DMG being much smaller increase.

For HP, an evo1 hero at level 66e1-68e1 will typically be match the HP of its level 180 counterpart and 132e1-135e1 for DMG. But at 66e1-68e1 an evo1's hero DMG will still be well under will that of the level 180, but rather be close to that of level 104-110. It is not until an evo1 hero gets to level 132e1 that its DMG becomes a close match for its counterpart at level 180.

In battle simulations an evo1 level of between 100e1 and 120e1 typically matches its level 180 counterpart. But this does vary from hero to hero with some heroes able to match at 100e1 and others only barely at 120e1.

First Evolution Requirements:

- Hero must reach 10 Stars (at least level 180 )

- 1 Evolution Rune (can be obtained by spending 1000 Fame collected from Lost Battlefield)

- 1,000 Red Crystals

- 1 duplicate of the same Hero, you can provide the duplicate by 3 ways:

  1. Selecting the same Hero from the Heroes Altar (before, unlock the Hero and remove all the Crests)
  2. Selecting the same Hero Card from the Warehouse
  3. Providing Shards instead of a Hero duplicate while:
  • For Heroes that can be obtained by Shards you will need to provide the amount of the Hero cost

All Experience gained by the hero after reaching level 180 (10 Stars) will be returned in Bless Tome experience books (500,000 exp), typically rounded up to the nearest 500,000 exp.

Second Evolution Requirements:

- Hero must reach 10 Stars of the first Evolution system

- 5 Evolution Runes

- 2,000 Red Crystals

- 3 duplicates of the same Hero

If Hero has a higher level than 185, the Experience gained after reaching 185 will be returned in Bless Tome || experience books (500,000 exp).

Honor Badges aren't used for evolving heroes but they will be used to level them up.
