Restore HP to target proportional to amount of damage target has taken.
Curasa is a spell available to the Medic role. It heals one target based on the damage they have taken, meaning the lower the target's HP, the more it heals. If Curasa is cast on a target with full HP it will heal a mere 1 HP. Curasa is useful on party members who are low on HP (mid yellow and red region), but useless on those who are not seriously injured. When used by the AI, the party members will only cast it on team members whose HP is below 50%.
Curasa is learned by advancing as a Medic in the Crystarium system and is available to:
Curasa returns as a Medic skill that heals the target based on how much health they have. The less they have, the more it heals, however when target has more than half of their health left, it will heal for much less, so it is best used when target is very low on health. The spell's effectiveness is greatly reduced from Final Fantasy XIII. Both Serah and Noel can cast the spell.
Curasa is a Bravery attack for Lightning usable in Medic role in the pre-release of Dissidia 012 Final Fantasy. Since this conflicts with the fact that she cannot learn it in its original appearance, it is renamed Cura in the finalized version.
