Skylanders: Ronald And The Coin Of Wonders

Ronald is a unicorn/dragon hybrid just like Whirlwind but his breath and rainbow attacks are very short and weak which makes the dragons and unicorns tease him about this and telling him that he won't make any friends even Whirlwind or Cynder will not be his friends. Due to being bullied, Ronald went to a cave on the other side of the village on Dragicorn Peak. He found a cave to rest in. And there he found a coin. But what Ronald didn't know that he was in the Forbidden Cave and it was called that because that coin is inside here. The coin was no ordinary coin because it was the Coin Of Wonders. It's half good and half bad. The Coin can give a being more power and strength but the being can also attack other beings who they helped out.
But Ronald didn't knew about the Coin or the what it can do to you, so he touched it and the Coin became bonded to him. How can Ronald break free from the Coin's spell once he was bonded to it?
