What you were expecting to happen, and what actually happened?
Opponent team has full line up of 4 members. I used the Imp of Love ability, and received a message that it cannot find any target to Charm.
This also happens sometimes on 3 members teams as well.
What are the steps to make it happen again?
Doesn’t happen all the time, but play about 10-15 games with the Imp of Love and you should be able to see this occurs at least once.
