I really hope you are joking about your bars and stats - else Ares dcz is very weak indeed. Interserver dlw pls.
it might be a useful skill - as duffs and blind and slow and stun - however the way it is used in diez is silly. Nooby sins just spam illusion on whoever they see. I am a mage (papermage) and I am very very often illusioned. Bfd is illusioned half of the time - does not always bother to cure it - I understand cure pots are heavy and needed for the real duffs.
But ppl believe certain things are not to be used on 1vs1: duffs for example. Well if duffs are out so should illusion.
Party fights are different - but in 1vs1s or when you outnumber your opponent greatly what is the point?
Btw: does illusion actually work?
he never lies
