Axie is hands down one of the most valuable heroes you can get. She can carry you far in the campaign, arena and ice fortress. The first skill you should max is her 75% Line AoE Charm. This ability allows you to turn your enemies Blacksmith or Thunderhoof into your killing machine allowing you to beat people 10~15k higher in BP than you. What pushes her over the top is her 2nd skill, a cleanse that doubles as an AoE regen which can be clutch when you need some sustain.
Verdict: Axie is a very powerful hero. With her mind control and cleanse abilities she is just too good to pass up.
