The facts on the card
The card carries these facts from its Wikipedia article.
- IMF not only describes the formation and evolution of individual stars, it also serves as an important link that describes the formation and evolution of galaxies.
- The IMF is often given as a probability density function that describes the probability for a star to have a certain mass during its formation.
- It differs from the present-day mass function, which describes the current distribution of masses of stars, such as red giants, white dwarfs, neutron stars, and black holes, after some time of evolution away from the main sequence stars and after a certain amount of mass loss.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Initial mass function article was read about 17,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 69 and blocks with 63: each hit it takes is cut by 25 %.
How to get Initial mass function
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
