Each Hero has an Elemental type which grants them advantage against Heroes of a certain Element, while also making them more vulnerable against another Element.
The strengths and weaknesses of each Element go as follows:
⦁ Fire (red) is strong against Nature (green)
⦁ Nature (green) is strong against Ice (blue)
⦁ Ice (blue) is strong against Fire (red)
⦁ Holy (yellow) and Dark (purple) Heroes are strong against each other, but weak against their own Element.
The damage done by your troops is greatly affected by the Elemental affinities. Especially in PVP, it can make a huge difference if you combo hits an enemy who’s at disadvantage – you’ll deal double damage on each hit.
Remember that, when in battle, you can always check the Elemental chart from the upper corner of the screen!
