Answer
Natural philosophy. Natural philosophy 72 · Axe 69 · Chromatic aberration 66 · Aura 63 ATK in WikiCards.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- It is caused by dispersion: the refractive index of the lens elements varies with the wavelength of light.
- The refractive index of most transparent materials decreases with increasing wavelength.
- Since the focal length of a lens depends on the refractive index, this variation in refractive index affects focusing.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Chromatic aberration article was read about 98,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 66 and blocks with 55: each hit it takes is cut by 22 %.
How to get Chromatic aberration
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.
