Madeline is currently the best infantry hero that you can get in Call of Dragons. What makes her extremely good is the first skill that allows her to absorb damage, deal counter damage, bring in more units, and so much more. With her, you will be able to survive for a long time while dealing a lot of damage to all enemies nearby. What is great about her is that she is extremely good at doing PVE content, like when you have to tank Behemoth. So no matter if you are free to play or pay to win, you have to get Madeline.
