I'm not the DM but being completely immune to all illusions at 1st level is overpowered. Resistant is fine, able to try and shake off illusions more than once, sure, but outright immune to an entire school of magic from the start might be a bit much.

Kitsune's are immune to illusions but are extremely weak physically. They are not too powerful concerning damage either...it's pretty much only an illusion/anti-illusion expert!
