Job Location: Silent Glaciers
Job Description:
An old woman from a nearby rural outpost is familiar with the Cave of the Hitodama. For years it was believed that the dead must be put to rest and kept at rest using a sacred ritual. The old woman has plenty of money, gathered from believers of the ancient rituals and has hired you to escort her to the dangerous frozen cave, across the cold glacier pass, and into an area rumored to be well traversed by the dead. She wants you to guard her inside of the cave from angry spirits and then escort her back home safely.
Description of the cave:
The cave is located near a loosely-frozen delta facing the ocean in a northerly direction. It is about five miles long, stretching into the arctic mountains of the region, with several deep crevasses spanning the narrow width of the cave. Frozen pathways and stone pathways alike are layered in frost and ice, but lead back to the rear of the cave. The polar cave has ceilings as high as 8 m and as low as 1 m. There are no secret or hidden pathways, just one direct route that the sea itself carved out of the land during times of storms or floods. Along the length of the cave runs a slow moving, 1 m wide river which culminates in a small but deep hot spring in the very deepest point in the cave. This river occasionally freezes over, though due to protection from wind, can more frequently be found moving from the back of the cave to the sea, starting from the spring itself.

Enemies:
Weak: Wild beasts: Wild animals traverse the tundra looking desperately for food. The wild animals most likely to cross paths include lone Reindeer, Dire Winter Wolf, a pack of Frostfur Weasels, or Blue Horned Ram. These animals (or in the case of the weasels the whole pack together) can deal D rank damage and take 2 D rank damage to take down.

Normal: Wayward Ghosts: In their former lives, these ghosts were simple civilians with simple minds and a curious nature who found themselves killed in the cave from either frostbite, wild beasts, or the poisonous spores of cave moss. Now, the ghosts which are usually gentle have become angered and strike out against those entering the cave. They deal C rank damage and take 2 C rank damage to disperse.

Strong: Angry Hitodama: Spirits in the form of small glowing bulbs turn red when disturbed and form into deceased mages. These dead mages use various kinds of elemental magic and take 2 B rank hits to take down. They tend to use javelins if their foe is at a distance and willfully target any who enter the cave. They tend to use burst spells first, and bladed weapons second. Their spells include elemental versions of the following:

Thrown elemental javelin: In the form of ice, lightning, or fire, these javelins deal D rank damage each and two can be thrown at a time (one in each hand of a ghost mage)
Elemental blades: In the form of ice, lightning, or fire, these blades can be as long as a katana, as short as a dagger, and be functionally whatever blade desired once drawn. The weapon deals C rank damage.
Elemental burst: An explosion burst of ice, lightning or fire around the angered ghost mage can deal B rank damage.

Reward: 20K jewels
