Diamonds are the currency used in Roblox Royale High, and it is essential that you get as many of them as possible, so your character is able to wear the latest clothing on offer in the game. Obtaining diamonds is not easy, and they can take time to get. The following guide will tell you the fastest ways in the game you can farm them, these methods include login daily, purchasing diamond multipliers, sleeping to level up, and collecting diamonds via the art studio.Login Daily
The easiest way in which you can get free diamonds is to log in to the game each day. The more consecutive days in which you log in to Roblox Royal High the more diamonds you will be given as a reward each subsequent day. You can login up to 10 days in a row to receive the bonus diamonds, which will give you a total of 12,000 diamonds. Diamond multipliers do no work with the login diamonds.Diamond Multipliers
If you want to use the most efficient method of farming diamonds in Roblox Royale High, you will need to spend real money on Robux to purchase diamond multipliers. You will be able to buy diamond multipliers by going to the Gamepass Shop, which can be found under the shopping tab. There you will be presented with a Double x2 Diamonds and a Quadruple x4 Diamonds option, the double option can be purchased for 749 Robux and the quadruple option can be purchased for 1,649 Robux. These are both worth getting if you want to invest in the game, as you can stack them both together to x6 diamond each time you level up and gather diamonds around the map.Sleep to Level Up
Another easy way to get free diamonds in Roblox Royale High which takes no effort is to sleep and level up. If you go to the 'Missions' tab, you will see that the energy or your character slowly depletes as you play the game. You can reverse this, so you replenish the energy you lost by sleeping in your apartment bed. Whenever you gain more energy you will gain experience towards your level and when you recover 160% energy from sleeping up you will get a level up. Each time that you level up in Roblox Royale High you will be awarded 300 diamonds (if you have both diamond multipliers, your reward will be 1,800 diamonds). Take advantage of sleeping whenever your energy level is low to not only regain your energy but to also level up and get free diamonds.Glitching the Art Studio Window
The best way to actually gather diamonds in Roblox Royale High is glitching the Art Studio window. You will find the Art Studio on the second floor of the campus by going right if you enter it where you spawn. Take a look at the video below to get a detailed explanation as to how to perform the glitch.
