烙印矿洞

{{spoilers| Go immediately right from the cave entrance for the beginning. You'll be jumping on bars along the wall. Jump on the bars carefully. Beware of falling debris from the ceiling; it may knock you down/off the beams. Debris falls when the screen shakes. When you reach the point where you can`t follow the bars anymore, jump on the top of the suspended vertical platform (or glide to the bar in step 4 to skip some jumps) Jump onto the next platform and test your skill on the last tricky bar. Jump straight across the gap and follow the ledge. There are a few more bars to jump on, but they are considerably easier than the others. The last ledge will give you the Grand Chest and the achievement.
