Killing the Kapros are easy to do as long as you manage to get onto its back and stab it repeatedly with a sword or if you’re lower on level just keep shooting tranquil arrows and order all your pets to finish it off. But beware find and stay on high ground ASAP these things jump out of the water and pounces on you with knock back attacks and is way more agile than sarcos and often stick around in sarco packs of about 3-4 or more. So if you’re travelling near a swampland and you see these things jumping out of the water. Remember what I said.
This guy is my favourite so far, right from when I first meet him, I was a noob and wandered close to a swamp well he came flying at me missed and disappeared behind me, I'm like what the neck was that, climbed a big arse rock asap and looked around, bugger came bounding back towards me and leapt straight up that rock like it was a mole hill.
Tamed the bugger and took him hunting, came across my first raptor and shat myself thinking oh rap I am screwed, nope Kappa flys over my head, collects the raptor and pile drives it into the ground several meters away, hilarious. Always fun times with Kappa around.
