When clash of lords 2 heroes evolve update came out, I was thinking ‘WOW, what do they mean evolve – do they mean pounder will be bigger than that :|’. But rest assure, it isn’t that type of evolving, it’s more to do with their passive skills than their actual figure.
It all matters about if you meet the requirements of the evolve stage. To locate if a hero is eligible to evolve or not, head to the hire heroes tab, the click on more and you should see a evolution unlocked – as seen below picture.
Once you know a hero is eligible to evolve, click on the hero and click on the left hand box of the hero – a window should pop up showing you the requirements to evolve the hero as pictured below.
I am 90% eligible to evolve to the next level, but do no have enough mutagen to proceed to the next step. This is usually the general resource that most people run out of, you can buy more mutagen in the gem shop as pictured below.
Generally It is not known if you can earn mutagen via treasure box or other means other than gems, but i’ll keep everyone posted!
Update: Treasure boxes do give out mutagen!
