In all honesty the starforce boom rates are a complete joke.Starting with 30b trying to get my sup pendant stars up i started at 18 stars. I have 2 sup pendants an old one 17 stars and my current with 18 stars. I didnt even pass 19 stars on any of them.I boomed 7 pendants at 16-18. At GUESS WHAT 2% chance.I'm left with trying to starforce my old pendant to 18 or at least hope to get it again with the 9b i have left....... 10 pendants later 12 star gollux pendant ...... 4b left 11 pendants used im left with a 12 star pendant im giving up.
