Be able to put your XP into a bottle to prevent losing it.

Be able to put your XP into a bottle to prevent losing it. Many people die with a lot of xp and are only granted a little bit back. I feel it is unfair that you cannot control whether you die or not. You can store your tools and resources to prevent losing them but you cannot do anything with your xp. I feel like if you could store xp somehow it would be a very great part to the game and make a lot of people happy.
