- Freshly prepared aqua regia is colorless, but it turns yellow, orange, or red within seconds from the formation of nitrosyl chloride and nitrogen dioxide.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Aqua regia article was read about 190,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 64 and blocks with 52: each hit it takes is cut by 21 %.
