It's plain to see that people have taken a shine to the illusioner, but I've also heard that the devs think the illusioner needs a significant rework before they can be added properly... So, here's my attempt at providing a solution to this...
Judging from their clothes, their spells, and the name for their type, it seems that illusioners have some measure of skill involving things like stage magic (perhaps as a hobby on the side), but more importantly, it seems that they may potentially be the evokers' personal assistants and even enforcers, secretly helping the evoker keep an eye on other underlings by disguising themselves for whichever job the evoker assigns them- whether in the mansions or at pillager outposts- and reporting back to the evokers.
So, I propose that the illusioner should be reworked accordingly in several ways:
- The illusioner, when not found either in a raid (in which case they would appear starting at wave 8) or in an evoker's presence, should be disguised as some other type of testificate mob depending on the location where they are found, dropping their disguise upon attacking, being attacked, or being interacted with by players attempting to trade; this would combine two highly requested ideas.
- By default, the illusioner should attack using throwing knives (these do about 2-5 HP of damage per hit), which would make the illusioner more unique while preserving the fun that people talk about having in fights with the them, though the illusioner may instead wield a different ranged weapon depending on their initial disguise (e.g. if they were previously disguised as a pillager, they would wield a crossbow).
- Illusioners need to have their full HP reduced from 32 to 24, putting them more in line with other illagers, as well as cutting down on the needless annoyance factor that seems to be holding this mob back in the eyes of people who summon these.
- The illusioner should drop their throwing knives (due to always having them on hand), and possibly an emerald upon death.
