You can only get four chests through wins each week and the limit will reset once the week is over, but if you get a chest with a specific champion then you can no longer do it with that champion until the season resets. The other way you can get chests is to buy them from the League of Legends client store. One chest will cost 125 Riot Points but has bundles ranging from almost 200 RP to nearly 2,000 RP. You can buy up to 25 chests a day and this will not be counted towards your weekly limit.
A high fever is when the body temperature rises above 103 degrees Fahrenheit in an adult (or above 101 degrees Fahrenheit in a child).
Fever: Causes, Symptoms and Treatments. Fever (also known as pyrexia or controlled hyperthermia) is when a human's body temperature goes above the normal range of 36-37C (98-100F) - it is a common medical sign. As the individual's body temperature goes up, there may be a sensation of cold until the temperature plateaus (stops rising).
