FOR ROYALTY

Tips:

- Get 50% of that class diamond already so you can do all of them and get royalty after 1 prestige

Steps:

1. As soon as you prestige, equip your gun that has the diamond camo.

2. In the first game you get into, complete 1 of every single challenge again. 1 headshot, 1 bloodthirsty medal, 1 kill with no perks, 1 kill with no attachments, etc. (you get the idea).

3. It will tell you that you completed that challenge for the very first time and award you all the xp for it again.

4. Once you complete all the challenges on that gun again, it will add 1 to your royalty camo challenge counter.

If you want to get this done in 1 prestige, get 50% of that weapon class already diamond so you can repeat this method on each gun.

For DIAMOND

Steps:

1. As soon as you prestige, equip your gun that has the most challenges completed on it towards diamond camo.

2. In the first game you get into, complete 1 of every single challenge that you already have completed, again. If you are 4/7 challenges completed for the diamond camo before you prestiged, complete 1 of each challenge that you have already done.

3. Let's say I have every challenge done except longshots (total of 6/7 requirements done for diamond). I only need to complete 1 more challenge to get the full 7/7 requirement for diamond, so once I go into a game and complete 1 challenge (for example, 1 kill with no perks or 1 kill with no attachments etc.), it will complete the 7/7 camo challenge requirement to unlock diamond even if I don't have all of the longshots completed.
