Weapon Improvement System

My suggestions is an enchantment orb that spawns in the middle of the map underground and you can use it if you have enough kills without dying. You can use it to permanently improve your weapon for the duration of the match. This does not make just joining harder however, for i have devised a counterbalance. There are two options to upgrading. One improves something and the other improves something else, if you pick one then the other gets worse. You can take this back at any time you want, so if you don't like one you can choose another this works for bows, swords and pickaxes. It also works for some utility items like bombs, with blast radius and damage. I hope you like my idea!
