It was a nice idea and I don't understand why it doesn't seem to work like the Violet vanity.
The Violet vanity helmet can be worn with other armour vanities but the Ashera can't because of the head size. Also, it does need the wearer to use a staff to have the full effect.
I tried it on via the auction and with a gun it just doesn't work. The helmet with a different dress looks way out of proportion but that's my opinion. Some people may think differently.
I'm sorry but I don't think it's worth the amount of plat either.
Like I said, it was a nice idea.
