Growth rate
Growth rate is the experience curve a species follows, which sets how many points it needs for each level
Six curves exist. To reach level 100, Erratic needs 600,000 points, Fast 800,000, Medium Fast 1,000,000, Medium Slow 1,059,860, Slow 1,250,000 and Fluctuating 1,640,000. Generation I used four curves; Ruby and Sapphire added Erratic and Fluctuating.
Main-series games; introduced in Generation I, Red and Green.
