I'm not sure how long but the custom enchants have stayed the same for quite a while now and we haven't had any new ones so I'm just suggesting that like you make some new ones or maybe not some new ones just upgrade the levels like plasma 3, autojump 5, autospeed 3, but they'd be extremely rare and hard to get hense why they're so op lol, Or make an enchant where it fixes your armour slowly when you're out of combat for a certain time. Things like that to make it more interesting and more fun for the OG players such as myself.
