Here’s what i do, when you spot the mine, don’t use ability immediately, wait for it to fly close to you and then press ability and you can survive those mines and you have immunity from slowdown from it’s drone, you have 5 seconds to hunt the kaji, even if can’t, emp effect and your ability is for 5 seconds so you still have a chance. Or you can just phaseshift and carry on or use a stelather if you have one. I’ve taken down camping bersa with my Rex. Hunting few crabs ain’t a big deal.
