Wandering Trader simple changes.

The Wandering Trader spawns way to frequently making leads very easy to collect, not to mention the frequency of the time the trader appears is very annoying to players as players don't find it's trades appealing and just kill the trader and it's llamas just for it to reappear minutes later bothering the player into killing it time and time again, as a solution to this I highly recommend making the Wandering Trader an extremely rare encounter such as the same rarity of feeling when you find a naturally spawned pink sheep our ancient debris, but then there's the issue of trades, if the trader has a rare spawn rate it's trades naturally need to be better, as a solution he could sell enchanted books and tools, but the Villagers already do that, well the trader will sell them majorly discounted, the rarity of the player actually finding him will make up for the discounted tools and enchant books and with the Wandering Trader offering discounts on Enchanted Books and Enchanted Weapons players will actually use there time with the trader before he disappears, but instead of him leaving right away I say he should stay until the player buys all his available trades, then he'll leave and won't actually return in the world again, it will be a one time encounter as if he left forever to sell his goods to others far far away.
