I should have said that the repairs I already undid was with the crowbar, the ones I can not undo are the ones with the loose nails and I have 2 or 3 hammers in my inventory. I went and changed from a mage to a fighter just so I could equip the brimstone hammer in case that was the problem but it did not work. So, I have a hammer AND the crowbar but I could only undo the repairs at the sight on the east side of the map.

In the future, do not start another thread with a continuation post for an already existent thread. The whole point of a thread is to capture the posts relevant to a particular topic. By splitting it up, you make it harder for people with the same questions to find the answers already given.

The hammer you need is the hammer that was available in the house with dead dabus inside.

Brimstone Hammer WON'T WORK! Nor any "hammer" weapon. The tool is what you need, and I really don't remember where you can get another such hammer if you missed the one from the dead dabus.

I think one of the merchants on the square (where Lim-Lims are for sale) sells them.
