A Helping Hand is an Iki Island side tale where you keep running into Emotaro, a man rebuilding his home alone after the Mongols burned it. Help him four times and you get the Charm of Iron Grip.
Part 7 of 16 in Tales of Iki
The first time you meet Emotaro, he is learning to build a house with no experience and no supplies, so you give him wood. Later you find him again and give him wood and hides. On the third meeting he tells you where he is building. Visit him in the clearing west of Fort Sakai to see the finished home.
This tale is spread out, so do not go hunting for him. Keep exploring Iki and the next meeting tends to come up on its own.
