Please keep english on this topic.
Level 80 rings does have their chances based on the usual number from each class at the beginning: DK = DW > ELF > DL = RF = SUM.
Dungeon, Atlans & Lost Tower does have their *move by feet* level changed to the M level. Rest of medium/higher maps does keep their -10 levels difference on feet vs move.
I'll check if there were some gates in Lost Tower that got actually a higher level on feet, by mistake.
