Mikhail and it's succesor.

So we know that we can make an UA with this class.
But I already made one with a CK. Question is:
Can I make another one with Mikhail? Or is it abide to 1 UA per account?

UAs are limited in quantity only by number of character slots.

You can make as many UAs as you want, You can even delete your CK and Mikhial and your UAs will still be around. Make another one, theres another UA for ya.

Seeing I just made an UA bucc with my 150 Mihile next to my UA NightLord.
Yes, I confirm it´s possible.
