Troubled Waters is an Iki Island side tale in Gonoura, north of Zasho Bay. A raider crew has teamed up with the Mongols and is using hwacha against locals, and you go looking for a woman named Sugi who can help stop them.
Part 15 of 16 in Tales of Iki
Rumours say a ship is raining burning arrows on the west coast. Ride there and you find a burning raider ship and wreckage on the shore. A survivor tells you who did it and who might help.
Get off the beach while hwacha fire rains down. Run along the coast to the right and keep rolling to dodge arrows. Then search the area for Sugi, who is in a smouldering house. Talk to her, follow her to meet some visitors, and defend her village when Yamaneko's crew attacks.
Do not stand and fight on the beach. The hwacha volleys hit hard, so keep moving and roll until you are clear. When Yamaneko's crew raids Sugi's village at the end, stay near her and the villagers so the raiders cannot pick them off. Bloodletting picks up right where this tale ends.
