Corpse beyond the pillar beside the pond lift

Ancient Ruins of Rauh

Starting Site of Grace: Viaduct Minor Tower

1. Enter the Realm of Shadow after defeating Starscourge Radahn and Mohg, Lord of Blood, by touching the withered arm in Mohg's arena.
2. From Highroad Cross in Scadu Altus, follow the main road north to Shadow Keep's southern gate. Ride the entrance lift and activate Shadow Keep Main Gate grace.
3. Defeat Golden Hippopotamus in the plaza. This is the front-door route; the flooded Church District provides a different way into the keep.
4. From Main Gate Plaza, leave through the west-northwest doorway, pass through the armory and climb the stairs. Continue up the wooden steps to the dining hall, where two Black Knights guard the route.
5. Leave the dining hall through its southeastern exit to the upper rampart. Follow the rampart past the burning boats and watch for the small Shadow Militiamen hiding beside them.
6. Take the stairs leading north-northeast toward the large lift, passing the Fire Knight in front of it. Ride up and activate Storehouse, First Floor grace.
7. At Storehouse, First Floor, take the western side passage and lift down to the lower jar rooms. This is the West Rampart branch, rather than the stairs climbing toward Messmer.
8. Follow the hallway through the rooms with living jars and the larger jar-filled ward. Watch for the smaller enemies waiting beside doorways, then use the western exit and stairs to reach West Rampart grace.
9. Cross the long bridge west toward the Ancient Ruins of Rauh. Salza waits at the far end and calls down fire as you approach. Use the bridge's sheltered sections to interrupt his view, or ride Torrent to close the distance.
10. Defeat Salza at the western gate to receive Rain of Fire and Salza's Hood together. Messmer and Romina are not required for this selected route.
11. Go through the doorway behind Salza. Take the doorway on the right, follow the stairs to the lift and ride down to Viaduct Minor Tower grace.
12. Leave Viaduct Minor Tower by its southwestern stairs, then head southeast across the grassy upper ruins toward the small pond.
13. Find the lift just southeast of the pond. Before riding it down, go past the far pillar and loot the corpse holding Spirit Calculus. This fixed pickup is available without entering the lower Bloodfiend room.

11. Go through the doorway behind Salza. Take the doorway on the right, follow the stairs to the lift and ride down to Viaduct Minor Tower grace.
12. Leave by the southwestern stairs and follow the path west as it curves downhill. Turn northwest between the lit braziers and large pillars to enter the covered ruins. This is the upper ruin route, separate from Rauh Base below.
13. Watch for the Curseblade beside the pillar near the pot-carrying shadow enemy. Continue northwest, look right for the large double doors and open them.
14. Descend the stairs into the scorpion chamber. Draw the large scorpion away from the smaller ones dropping from the ceiling, then clear the next corner. More scorpions drop beside the corpse there.
15. Continue west and southwest down the ramp to the next chamber. Find the shadow enemy carrying a pot in this room and defeat it for the fixed bundle of three Spirit Calculus.
16. This particular three-item reward is collected once in the journey. It is separate from the rare regional wildlife drops; resting does not repeatedly award the same guaranteed bundle.

12. From Viaduct Minor Tower, go down the southwestern stairs into the grassy upper ruins. Hunt the horned wildlife around the open ground and pond, checking the drops after each kill.
13. Rest at Viaduct Minor Tower to reset the animals for another run. These are the upper Rauh animals, rather than ordinary wildlife reached from the lower Moorth valley.

Notes

• Used to craft Spritestone. Each craft needs one Spirit Calculus, one Rauh Burrow and one Beast Horn after learning Antiquity Scholar's Cookbook (2).
• Regional horned wildlife in upper Rauh can drop it rarely. Those enemy drops are renewable, but a few hunting loops may produce none.
• A fixed corpse near Viaduct Minor Tower and a three-item bundle from a particular pot-carrying shadow enemy provide checked alternatives. The three-item bundle does not repeat every time you rest.
• Similar-looking animals in another region do not guarantee the same loot. The selected hunting route is in upper Rauh, reached from Shadow Keep's West Rampart.
• Spiritgrave Stone is a different ingredient. Fire Spritestone is also a different recipe, using Ember of Messmer instead of Spirit Calculus.
