I'm not good with affixes/suffixes, so I was hoping someone could help me confirm this.

Is it possible to roll a ring with the following stats:

• 9 Min or Max
  
• Mana Leech
  
• 15+ Dex
  
• Extras
  

I've been looking around but haven't found one with that specific combo of damage / ML / dex, so thought I would check to see if I'm wasting my time..

9 Min or Max --> suffix (min dmg max is 9, max dmg max is 5)
Mana Leech --> suffix (max is 9)
15+ Dex --> suffix (max is 15)

could get up to 3 more prefixes on it like attack rating, mana, res

Legend, thank you!

Is it really just 3 prefix/3 suffix, and you roll any combination as long as you're only picking 3 from each list?

Up to 6 affixes for rares and up to 3 prefixes and suffixes, yes.

I don’t think u can roll just the mana leach without getting life leach
Most common roll would be
Min dmg
Life leach or ar
Str
Dex
Life
Mana or res

no
