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).
No treatment is necessary for a mild fever unless the person is uncomfortable. If the fever is 102 or higher: Give an over-the-counter medicine such as acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) as directed on the label. Check with your doctor first if you have any medical conditions or take other medicines.
