No worries! I can definitely alter it! Give me a sec.

EDIT: Changed it up. Does this new readied action work? For future reference, can Torus make a mound with Mold Earth, with surrounding loose dirt, if he can't simultaneously excavate the vicinity's ground?

Yup, it should function as an improvised weapon that forces a DEX save instead of an attack roll, given the Shape water cantrip in itself has no damage values. As for the loose dirt, sure. If there's loose earth somewhere he can move, he can build a pile out of it somewhere else. But remember, it's five feet per turn.
