You'll be restricted to hunts that are within your level range once you've entered the Hunt section of Guardian Cross. Here you'll have the chance to either take part in regular hunts, or use some of your Cross Coins to enjoy an enhanced version of the map where you're more likely to find rarer Guardians during your safari.

You only have 60 seconds on each attempt to bag as many Guardians as you can, and you should make every shot count as reloading will eat up a fair chunk of this precious time. Once you've finished off a roaming monster, follow the red arrows to move your scope towards the next prey.
