I put one of these on one of my traders and it just today hit 100% of the stats shown (33ac 350 HPs 360 mana/end). /played shows 262 days and 17 hours.
I'll update when it hits the full max.
Update: At some point in the 12 hours prior to 725 Days and 17 Hours it reached the full max of 39AC 420/432/432 etc.
