Easiest way to achieve ko with barely effort find a big rock that has a tree close enough to the rock that your body can fit snuggly aka anchoring .you anchor him in that spot and throw as many rocks as you want at his legs never aim towards upper body does more damage and can kill him, 89% chance of death so be careful sit tight make sure you have a lot of rocks and if he runs away aggrieved him and take him to the same spot. Hope this helped have a good day.
