I think that the Deed that is called Deprivation (No pickups will be found in the level) should still spawn Tomes and Grims.
Deeds are a fun idea and I understand that it is what they are, fun and to give us some extra challenge. But I think that Deprivation should still spawn Tomes and Grims so you have a chance to get better loot at the end.
I knew about the loot rat but I did not know that some grims spawn. Do you know which grim that spawn? My guess is that it’s grims that you have to “summon” like the one on The War camp?
