Day four’s Course will introduce another new mechanic to your the growing list, Wind Breakers, curious rings that will prevent any wind from passing through so you’ll need to be on the lookout and avoid them if you wish to score the Gold Medal here. You’ll find the Course starting locating to the east of Taishan Mansion in Jueyun Karst, Liyue (there’s a Waypoint right next to this).
Begin by following the first particle trail and you’ll come across your first Wind Breaker, you’ll have to either pass around these or go over the top, for this particular one, head around the side and collect the 1st Insignia. Continue to follow the particle trail by using Sprints to keep your height and then pass around the side of another Wind Breaker before returning to the rings to collect the 2nd Insignia.
Just past the next Wind Breaker, look to the ground to spot a well hidden 3rd Insignia. You’ll have to drop to the ground to collect it and then use the gust of wind just beyond it to return to the skies. Pass through the next set of rings and as you approach the next Wind Breaker, use Ascend to go above and collect the 4th Insignia.
Continue past these and you’ll see a set of rings on the left and another set on the right, take the right rings and soar up to collect the 5th and final Insignia. All that awaits from here are a few more rings with one more Wind Breaker in the way, avoid this and drop down to reach the Goal.
