Barta is an ice elemental damage technique in Phantasy Star Online 2.
Barta costs 20 PP to cast, and fires a piercing projectile in a straight line toward its target. Level 1 barta has an 28% chance to inflict freeze status. Increasing levels of barta, up to the maximum level of 15, require higher base T-ATK to learn, deal more damage, and have a higher chance to inflict freeze status, up to 30%.
Barta may be charged by holding the button down for a moment before releasing. Charged barta fires a larger projectile that deals significantly more damage for the same PP cost.
Forces have a number of passive skills to improve barta, including ice mastery to increase barta's damage, freeze boost to increase barta's chance of inflicting freeze status.
Like all techniques, barta may be set into the weapon palettes for rods, talises, and wands, or into the sub-palettes alongside consumable items and skills. Only characters with force or techtor as their current class or sub-class can use techniques.
New characters starting as forces begin knowing level 1 barta.
