Empress's Blessing - Does it work after level 120?

Related question: Can Mihile do the Cygnus Akarium quest line to raise the blessing from 24 -> 30?

EDIT: Nvm. Found the answer in another thread:

Mikhail stops acting like a Cygnus at 120, if you want to get 25-30 Blessing you will have to do Akyrum. However, its super easy for Mikhails because you can overlevel and just face stomp him
