Illager Vengeance, The Illusion, and the Enchantment storage

Here's an idea to give new purpose to the woodland mansion, finally implements the illusioner, and adds an idea I've had for a while. Here is my concept:

Evokers that spawn in mansions now have a special tag. If you kill all the evokers, you get a new status effect called The Very Bad Omen, or Revenge of the Illagers. After a couple of days, the effect goes away and the raid like event begins. A group of Illagers show up to attack you for killing the evokers. I am talking about vindicators, pillagers, and ravagers. After dealing with that, the Illusioner appears.

The Illusioner would be a new miniboss. He has the appearance of the Minecraft Dungeons version and it's attacks are a mix of base game and dungeons. Attacks are blindness, creates duplicates, bow, and firework attack. After death, it drops the Enchanter's Tome, which is used to create....

The Experience Alter!

The Experience Alter is used to store up to 20 levels of XP. It is crafted with the enchanter's tome, obsidian, soul torches, and chains.
