Oh really? Well if you say so... I received my information from
www.shadow-dragons.com which seemed like a reliable website for the game...
They say:
MND affects White Magic power, determines resistance to abnormal status and determines magic defense
and INT affects Black magic power.
It seemed to make sense that one stat is magic defense while the other is magic offense...
But your saying INT affects magic defense, magic damage and status change defense but MND only affects healing and holy magic? That doesn't seem right but if that's what you're saying...
Geez, if you're right, I'm not so sure I want to be an elvaan anymore...
