In TOWN, in abandoned house numbered "16", you can push a table around to reach a LORDSTOP guarded by a RENTER.
The fourth LORDSTOP appears to be on the other side of getting the GLAIVE from the CHURCH in TOWN, and using the GLAIVESPIN (colorful spinning attack you can trigger in the middle of TOWN) to anger the DESCENDER. Defeating it down the well will open up TOWN a bit more.
