The facts on the card
The card carries these facts from its Wikipedia article.
- The natural logarithm of x is generally written as ln x, loge x, or sometimes, if the base e is implicit, simply log x.
- Parentheses are sometimes added for clarity, giving ln, loge, or log.
- This is done particularly when the argument to the logarithm is not a single symbol, so as to prevent ambiguity.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Natural logarithm article was read about 270,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 71 and blocks with 70: each hit it takes is cut by 28 %.
How to get Natural logarithm
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.
