A Purpose for Illusioners

The Illusioners give off a hallucionation effect on the player. This new effect makes the player see something random for 10 seconds. It could be fighting the warden, in a cave mining diamonds or in a room fighting zombies ect (nothing too deadly) during these 10 seconds nothing can attack you unless you are hallucinating it, Any items obtained while hallucinating you will keep when you stop hallucinating and any damage taken while hallucinating will not automatically be regenerated when the hallucination stops.

When you kill an Illusioner they will drop a potion of hallucination this potion cannot be brewed but it can be combined with a dragons breath to make a lingering potion of hallucination which can be combined with 8 arrows to make 8 arrows of hallucination.
In a brewing stand you can combine the 3 new potion variants with Glowstone dust to make them last for 20 seconds and you can combine them with Redstone dust to make them last for 40 seconds. You can use these potions and arrows on mobs or players. You cannot kill mobs if they are hallucinating. Killing an Illusioner is the only way to get this potion. They can be found in raids and in woodland mansions. 

Vote for the Illusioners to finally get a purpose so the woodland mansion adventures and raids can get the extra spice they need to make Minecraft even more exciting!
