Effect
Sharply raises a random stat when HP drops below 25%. (Hold)
Starf Berry is one of the most powerful pinch berries, giving a +2 boost to a random stat when your HP falls below 25%.
You can get a boost to most of your stats. If you get lucky and boost the stat you need, it's amazing. If you get an irrelevant boost, it's wasted. High risk, high reward.
