- Other examples include the path traced by a molecule as it travels in a liquid or a gas, the search path of a foraging animal, or the price of a fluctuating stock and the financial status of a gambler.
- Random walks have applications to engineering and many scientific fields including ecology, psychology, computer science, physics, chemistry, biology, economics, and sociology.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Random walk article was read about 160,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 78 and blocks with 71: each hit it takes is cut by 28 %.
