I need advice on a new event

I understand that this question may have been asked here before, but I couldn't find it. My goal is to get Chrysalis in the new event, she is my favorite character. So my question is, do I have a chance of getting it when I only have helpers for the first two stages? Please share some advice on how to complete such events (this could be a link to an article) And I wonder how often you check this? For some reason, it's always easier for me to complete events with sapphires rather than with coins.
