2 Agi : 1 Dodge (supposedly) - Also, agility affects min/max AP, but to what extent is still unclear to me. For some reason it affects my chars in different ways. For my assassin, 2 Agi is equivalent to 1 min/max AP; however, for my Nature Guard, the effective ratio seems to be 4 Agi to 1 Min/Max AP; so it might just be that certain attributes affect certain characters in different ways. Agility also seems to increase crits, but by how much is unknown to me.
Power increases min/max AP, but its extent is unclear to me. It probably varies with what character you are, like Agility does. On my assassin, the effective ratio seems to be 4 Power : 1 Min/Max AP.
1 Vit : 10HP - Not sure what else it does, if anything.
1 Int : 10 MP - Supposedly it increases skill AP by a certain amount.
