We extend prior results of Cody-Eskew, showing the consistency of GCH with the statement that for all regular cardinals κ≤λ, where κ is the successor of a regular cardinal, there is a rigid saturated ideal on Pκλ. We also show the consistency of some instances of rigid saturated ideals on Pκλ where κ is the successor of a singular cardinal.
