If you can get up to 30 stamina before her event is over, it's worth it to try the Master level - there's a pretty good drop rate there. I don't know the exact rate, but I will say that I always spam the Master levels of these events until I get the drop because I like to have the unevolved forms of the units in my catalog, and it usually takes me anywhere between 1 to 5 tries. Very rarely have I had to try more than 5 times, although it does happen.
