Knights hero evolve is the new addition to the game that allow you to place hero cards on your knights. These hero cards will increase the stats of the knight but only as a means to an end for increasing the power of the knight for the sake of their battle assist bonuses. This guide will help you with unlocking knight hero evolve, explaining what it does, and help determine what kinds of cards should go on which knights. Note however, since finding large quantities of % attribute cards can be very hard, I will not be too picky about which stats to pick, as opposed to lineup heroes. Also note that it is very rare to find % attributes on cards, unlike runes, meaning that you should invest all good cards and the majority of your evolve points into lineup heroes above all else.



To unlock hero evolve on a knight, a player must have unlocked the battle assist for that knight. This can be by upgrading your SS grade heroes in lineup. Note that an SS hero in knights, despite having upgrades, will not count towards the battle assist count. Once a knight’s battle assist has been unlocked it will stay unlocked, so do not fret. To go about getting more SS hero souls for upgrades, look at the Egg Smash Guide or the Spending Guide for tips.

If you are experiencing problems with the knight hero evolve unlocking for a knight that has its battle assist unlocked, look at the workaround provided for this issue at the bottom of this guide.

Hero Card Acquisition-

Note that while there are recharge events that give out cards as rewards, the easiest and most consistent way to farm cards is through clan dungeon, so don’t miss out doing it weekly. You will also need the evolve points and evolution materials as well. You will need to sift through a LOT of cards to find the ones you need, as racking up evolve points to upgrade the equipped cards themselves. Keep in mind that upgrading cards will take a very large amount of evolve points and coin, and that maxing a single card can cost you over a 100l evolve points depending on grade and luck.


Battle Assist Lineup Bonus-

So, what do hero cards on knights do? Let me establish this before anything else: The cards DO NOT DIRECTLY AFFECT YOUR LINEUP HEROES. The only thing that cards do on knights is increase their power. That’s it. This increase in power comes from the stats and modifiers on cards placed on the knight heroes, and by increasing the amount of power a knight has, the more stats you get from battle assist lineup bonus. That’s the only purpose of knight cards- to make the knight battle assist bonuses more powerful. This means that the effects of % modifiers, while still greater than static stats for the most part, will not be as effective unless the hero is specifically built up to have lots of base stats.


Hero Card Placement-

Certain types of cards will be better than others on certain classes on heroes. This is a given based off hero base stats varying from one class to another. This section will help you determine what Is best or acceptable to use on different classes of knights. Note however, that this only really applies to % modifiers, and since you’ll be investing into lineup heroes well before knights when it comes to % value cards, this section will be only here as a reference for a far distant future upgrade for most.

HP Knights- Aim for HP% special stats on your cards for these knights as HP is quite literally the only stat that they have going for them. It will increase the power of the knight the most comparatively to other special stats.

Summoner Knights- Aim for DEF% Special stats on your cards for these knights as DEF is the greatest base stat summoner heroes have. Note that HP% is also acceptable here as a second option if you cannot find DEF% special stats.

Warrior Knights- Either DEF% or HP% will suffice here for special stats, as warrior heroes are adept at both, while maintaining a slight edge in base HP over DEF.

Bloodline Knights- ATK% is the best option for special stats for bloodline heroes as it is their best base stat. DEF% is also viable to a lesser extent if you can’t find ATK% special stats.



Don’t expect a fantastic amount of power or stat increases from these upgrades unless you have high level knights in your lineup. Battle Assist is an endgame thing to push, especially if you are struggling to maintain your lineup hero’s levels at par with your own. It is also advisable to only invest good hero cards/upgrade cards on knights that are high level and build up to already provide large amounts of stats from the battle assist lineup bonus, otherwise the return will not be worth the cost of evolve points and coin.


Tutorial (Fixing Lineup Bonus Errors)

If you are experiencing issues with Knight Battle Assist or Hero Evolve not unlocking upon meeting the required upgrades, please read below.

Make sure that your SS Hero Upgrades are:

-All on lineup heroes, as battle assist unlocks will not count upgrades SS Heroes in knight positions

-Equal to the required amount for the unlock (A Hela +4 and an Odin +2 make +6, unlocking Thunder Knight battle assist)

-Make sure to not confuse an SS Hero with no upgrades as counting towards Battle Assist Unlocks

If you still do not have the unlock and you are sure that you should, the please follow these instructions:

Acquire a spare SS Hero Soul and the corresponding S grade hero that you can upgrade with it.

Make sure the S grade hero has no levels, enchants, whistles, etc. and is not in your lineup (a blank/fresh hero)

Upgrade the S hero into an SS Hero using the spare soul. You should now have a level 15, SS Hero with no upgrades

Inherit any SS Hero in your lineup to this newly made, blank SS hero.

Your old lineup hero will now be outside your lineup and have no enchants, levels, or whistle, but will still have its upgrades.

Sacrifice this hero in altar to get back all souls used in upgrades and the base S Hero (You will not lose any heroes or souls by doing this).

Remake the SS Hero that you just broke down, but DO NOT upgrade with souls.

Inherit this hero back into your lineup with the SS Hero that temporarily took its place.

You should now have your original starting lineup prior to step 1, but without the upgrades on the SS Hero.

Upgrade the SS Hero back to its full upgrades, and knights battle assist/knight hero evolve should be unlocked!
