Did we play this right?
Wind Rider's ability wrote:
When fielded, reroll up to 2 opposing characters. Each die that does not roll a character goes to your opponent's used pile. Storm deals 2 damage to your opponent for each die moved.
I field Wind Rider, opponent has a single Gobby in his field. I target Gobby, who rerolls back to a character face. There are no other opposing characters to target. We ruled I couldn't target Gobby to reroll a second time. Is this correct?
