Monster Merging

* Monster merging is available at select times *

When new monsters are released in Battle Camp, typically the newest generation is stronger than the last. The older monsters become weaker and less valuable. Added in April 2017, this feature allows players to upgrade those old monsters with the stats of a newer monster.

This article uses these terms for each monster to make it easier to understand:

Monster A = Actual Monster
Monster B = Bonus Monster

Feel free to use them when discussing merging


  • Both monsters must be maxed
  • Crystals do not need to be maxed
  • Monsters must be of the same rarity and evolution
  • There is no limit to the number of times a monster can be merged
  • The merging feature can only be used once per day
  • It costs crystals and stones
  • Merging is done on the Pennypop Support page.
  • Merged monsters are tradable
  • Event monsters can be merged with non-event monsters
  • A non evolved or 1st evolution monster that does not sevo can be the Bonus Monster for your Actual Monster

The Result

The monster that you are customizing, your Actual Monster, gets certain attributes from the Bonus Monster:

A Simple Visual Explanation


Evolution of Merged Monsters

The reason it is suggested to merge monster when they are at their highest evolution is to save on resources. Non-evolved, first evolved, and second evolved monsters all cost the same amount. Rarity is the only factor. Taking 4 supers that second evolve and merging them with 4 other supers individually would cost 16 super crystals and 200k stones. Using a sevo monster as your Bonus Monster for your sevoed Actual Monster would only cost 4 super crystals and 50k stones.

Save Your Non-Perfect Evolved Mobs

That's right, with merging non-perfect mobs can have their base stats replaced, therefor they are now fixable! In fact, they can even be better than they were before. Think of it this way; the monster you choose as your Actual Monster to merge will have it's stats and zodiac completely erased. The Bonus Monster will rewrite these with it's own stats, zodiac, and R-Boost points if higher than Actual Monster's.

Mixed Merging Evolutions

If a monster is merged, it must still be evolved with the same type of feeder. That monster does not have to be merged, but the bonus stats will be less than a pure merge. If two of the same monster are merged with different monsters, they can still be evolved. Merged monsters will still carry over a bonus, but it will be reduced by evolving with non merged monsters. The previous theory was that after a merged monster was evolved with a non merged monster, it would result in a 50/50 split. Recently tested by myself, this is not the case. I merged a taillight for my PvP team, so I was doing it simply for the zodiac change and did not intend to merge any of the other parts going into evolutions of this monster. What I found when I evolved the merged taillight with a regular one was very interesting. Let's take a look at the stats of these monsters in the BCRank Catalog.

The Taillight is my Actual Monster and the Technicaller is my Bonus Monster.

In a regular merge, the Actual Monster will simply inherit the stats of the Bonus Monster like so:


When this merged Taillight is evolved with a regular Taillight, one might expect the stats to split 50/50 as if a Taillight was being evolved with a Technicaller and the result would be in the middle of a Smashlight and a Techniconqueror. However, this is not the case.

Let's look at the base health of these 2 evolved monsters and how you would expect it to work. The Smashlight's normal base health is 19,938 and the base for the Techniconqueror is 20,500.

AB Evo HP = (A Evo HP + B Evo HP) / 2
19,938 + 20,500 = 40,438
40,438 / 2 = 20,219

With this logic, you would expect the health of the mixed merge monster to be 20,219. Take a look though at what I got when I evolved it and maxed it.


The resulting health is actually 20,406. I am actually pretty happy with this because it is 187 more health than I expected. Where did that number come from though? After some playing around with the numbers, I figured it out. I have no clue why it is done this way but this is how it is done for a first evolution where one of the monsters is merged and the other is not. The Actual Monster only counts for 1/6 of the stats in the evolution while the Bonus Monster carries over 5/6 of the stats! I shall demonstrate with the HP and show the equation I have figured out.

AB Evo HP = (A Evo HP + (5 * B Evo HP)) / 6 19,938 + (20,500 * 5)
19,938 + 102,500 = 122,438
122,438 / 6 = 20,406

So yes, the math is really strange. If anything you would think there would have been a higher amount of the Taillight's /Smashlight's health, but this is how it is done for not only health, but attack and recovery as well.

Mixed Merged Monster First Evolution Calculator

At this time, I am currently working out the details of how mixed merges with sevos are calculated in addition to when feeders are both merged with different monsters for the first evolution. For now, I can at least provide this calculator for first evolutions so that you know what to expect if you only merge one of the two monsters you will be evolving. Enter in the stats for the evolved versions of the monsters found in the BCRank Catalog.
