Carina

Former commander of the Inquisition, she dropped out of the active service of the Church, and into Simon's, after an incident with a seed of corruption.

Story
Sister Carina is a devout Ivalan of the Subsecrationist school of theology, and a capital piece in the Church, due to her dedication. She is a good person, valued by her Goddess and interested in people's material and spiritual welfare while ashamed of petty internal Church politics. Carina claims to have always had a sense of Ivala's presence and communication.

On the other hand, she is also sometimes rigid, too secure in the rightness of her own convictions. She lacks the moral flexibility to acknowledge that her way is not the only way, but she has enough practical sense to accept help when the situation is dire:

But purifying the seed of corruption tests her capabilities. (And her humility too.) Simon warns her of the probable outcome but she is stubborn:

and overconfident:

Carina is corrupted in purifying the seed, and loses her connection to Ivala. As with Aka, Simon then has to fuck her, adding her to the party and harem, but only after reassuring her that she means something to him.

Starting equipment
She can only use weapons designed for mages, but her gear, excluded the accessory, can be from the mages' lines (complete) or from the warriors line (not complete).

 * Magical protection
 * Light Shields

Headgear: Steel Helm.

Bodygear: Steel Armor.

Accessory: Charm of Purity.

Tactics
She fills the role of the White Mage/Healer (although an armored one). As it happens with Qum, her offense is limited to weak melee. It remains to be seen if she will acquire more buffer abilities or if she will remain as a pure white healer.

Relationship points
Maximum affection is 100, and once there a girl should not lose affection afterward.

Most of Carina's affection boosts are related to the Church and helping people. She gets an unusually large boost from funding the shrine renovation, the largest in the game so far. Otherwise, just keep checking in on her and getting all her conversations.

Base value: 20.
