Changes and additions to Illagers and raids

We already saw potential for the Iceoleger to join the game but I would love to see it and other illagers from dungeons come to Minecraft. For example the Illusioner can already be summoned in creative and would be an awesome addition to raids. Along with the Geomancer and the one I most want to see in the game, the Enchanter.

An item the enchanter could drop is some kind of super enchanting book. It lets you pick one enchantment on your item to be a super enchantment. For example it could give you fortune 4 or efficiency 6 but you can only upgrade one. This could also add to PVP and PVE by making it so you have to be strategic in what enchantments you decide to upgrade

For the all of these illagers I think they should all drop unique items (e.g. more totems or something new) but can only spawn in specific biomes so you can't get everything from one single raid farm
