Hmm, never played a Reorx Cleric, so others should correct me if I'm wrong, hopefully, but let's see...
Forged Hammer: Makes a hammer (mace weapon), forget the exact name, but it's engraved with dwarven runes or somesuch. Physical damage, average based on level (much like a druid's Shilleigh staff), damtype is "Slice", flares occasionally for double (or more/less?) damage.
Shelter of the Earth: Much like Sanctuary, can only be cast on yourself. Damage reduction is less than Sanc, I think, maybe around Protectorate level? Also grants immunity to earth.
Roots of Rock: Grants some physical resistances, maybe something else I'm forgetting.
Flesh to Dust: Lowers physical resistances of target, much like "soften". Very nice in combination with forged hammer.
