Previously there were only Sharp I swords but they didn’t go away, they just became almost useless with the Sharp II swords being added. So what if they weren’t useless? Well you could always add a simple anvil and let people combine two enchanted objects and be done but that’s useless and arguably op, so my suggestion is a “ritual.”
Similar to an anvil, a ritual would let you combine two echanted objects to make one more powerful one. Unlike an anvil, this will take time. This should also be only in mid. For example: you have two sharp I swords and want a sharp II so you go to mid, find the ritual alter, throw in your two items (anvil GUI), and after that you wait say 15 seconds to get your item and it says in chat “xXRandomHiveUserXx is performing a ritual.” The more powerful the item, the longer the wait.
This fits the fantasy theme of Sky Wars with spells, adds an incentive to go to mid other than just the chests, gives more uses to enchanted duplicates, and provide interesting pvp scenarios. The only two problems I see with it is the technical side of coding a whole system for just better enchants and the fact it’d be useless in higher level play because all we do is rush.
