not sure where those are. mobs have been scrambled around af in R:O. Used to be that enraged had flame sprites. now it has wraiths.
IMO psy adds mdef. int adds mattk. For old Rohan. R:O i'm not sure anymore. could be rules have changed.
vit and str seem to add pdef. dex adds melee accuracy and more chance to crit. agi lets you dodge melee.
As far as I have seen so far dex adds nothing to magic attack auto attack. seems to hit 100% on my soon-to-be lock.
