Aion kinah: The ring adds +2 Mind Power, +1 Agility and +1 Intelligence to your character
FFXI Mithra Race Relations: FFXI Mithra has shown them to be a peaceful race and perhaps that is the reason why they have Aion kinah managed to live in peace with the Tarutaru in a very cordial fashion.
Earlier, at the end of the Age of Magic, the Tarutaru closed off their borders to all races except for the Final Fantasy XI Mithra. This was a great compliment to the Mithra race's peace loving quality as the Tarutaru secluded themselves from all other races.
FFXI Mithra Guide and Tips: When playing with a FFXI Mithra, start from their homeland of Windy. This will give you a Windurstian Ring. The ring adds +2 Mind Power, +1 Agility and +1 Intelligence to your character.
Suited Vocation: The Dexterity of the FFXI Mithra race is something that sets them apart from other races. Due to their energy, agility and dexterity an overwhelmingly high majority of the FFXI Mithra take to the profession of Thief.
Ranger can be a good profession for the Mithra as well. However, they are not as capable of taking blows as the Elvaans or Galkas. So they are likely to fall relatively early.
All in all their physique makes them foes to reckon with. Their nimbleness makes it easier for them to evade blows if they are bent on it.
