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).
A fever, also referred to as pyrexia, is an elevation in the body temperature above the norm. This is broadly defined as oral temperature reading above 37.5 degrees Celsius (99 degrees Farenheit) and a core body temperature (rectally) above 38 degrees Celsius (100.4 degrees Farenheit).Variations in temperature may occur depending on where the measurement is taken (oral, rectal, axilla). In infants younger than 8 weeks, a body temperature greater than 38.3 degree Celsius/101 degrees Farenheit should be considered as a high fever and requires prompt immediate medical attention.
