Vitality

Abbreviation: VIT
Vitality is a stat that is compared with an attacker's strength to determine the damage curve and reduces the maximum amount of damage that a character takes from a blow. Tanks, primarily Paladins, raise VIT in order to live longer and make a White Mage's job easier.
For every two points of Vitality, a character's defense stat is raised by one point.
Associated with the Element of Earth. Many items that are Earth-based add VIT to a player's Stats, such as Titan's Cudgel

*Note: a large amount of Vitality can also increase the potency of cure spells.
Ex: Koenig Schaller +10 VIT also has the same added potency as Valor Coronet's +10 Healing Magic Skill and has been tested accordingly; both results were of the same potency. 
*It has also been tested that VIT is a hidden modifier for the new magic shield effect on the Paladin job ability Rampart. The currently accepted formula seems to be: VIT*2 equals the amount of damage absorbed by magic stoneskin.
*VIT also affects the damage of Jump with a 50% modifier.
