When your character is of age you can ask various cats to be your mate (by talking to them)I’m not exactly sure who you can be mates with other than the rogue at the end of the territory
To become a warrior
-once you complete training and you get some time off go back to camp
-talk to Sunstar
-go to the medicine cat
-take the stuff they want you to take
-click on the map and go to all 3 locations and talk to the three bosses you will have to fight them first
-to get more damage and health you will have to use caps and fight smaller things such as snakes, fish, bears (start with snakes)
-then go back to clan after talking to all 3 bosses
-then tap on Ashfalls body
-the rest should be straight forward
