"Players must defeat as many levels as they can. You get full credit for levels defeated as long as your opponent is 1/2 your level or higher. You get half credit for defeating players lower than half your level at the time of the attack. If your level is an odd number, round down. For example, a level 65 will get full credit for attacking a level 33, but only half credit for attacking someone level 20."
