Wicked Woes game drop

This update would be a fairly small one, focusing on hostile undead mobs. The goal is to top off existing undead mobs to finally make them as good as possible, starting with variants. Firstly, the Sunken from Minecraft Dungeons. Simply add the same exact mob into the main game. Of course have them spawn similarly to the Drowned, mostly near underwater ruins. Upon death, they could give you coral, or perhaps a harpoon to allow you to shoot your own bow underwater. Next up, the Potent. A swampy variant of the zombie, it would spawn in water and try to stay near it. Whenever it gets the chance to attack you, it will begin to drag you to the water while simultaneously releasing toxic gas into the water, poisoning you. You must hit the Potent 3 times in order to escape. Upon death, it will drop a red or brown mushroom 100% of the time, and about 7.5% of the time, a lingering splash potion of poison. Lastly, we have the Necromancer. The idea behind it is that it's mostly the same as it is in Minecraft Dungeons, however here it will replace the leader zombie as its own mob, however also having higher chances of spawning. If you are experiencing insomnia, there is a 100% chance that one of them will spawn at midnight in most difficulties, and a 50% chance in easy mode. Other than that, they retain the leader zombie's spawn chances across all difficulties. Necromancers will drop bones most the time, though rarely can drop a Totem of Undying. That is all, thank you.
