Maximillian's Earthen Grasp has a range of 30ft. The spell description is ambiguous on where it can be moved once the Sorcerer (or Wizard) moves from their original casting point.
You choose a 5-foot-square unoccupied space on the ground that you can see within range. A Medium hand made from compacted soil rises there and reaches for one creature you can see within 5 feet of it.
As an action, you can cause the hand to reach for a different creature or to move to a different unoccupied space within range. The hand releases a restrained target if you do either.
Both my Sorcerer and my target for this question have a movement speed of 80ft (for the purposes of removing the number of rounds I need to detail below).
Lets say our Sorcerer casts the spell in round 1 of combat (15ft away from them). In round 2 of combat the original target has escaped and moved 15ft further away. Our Sorcerer has not moved.
It seems pretty clear that the Sorcerer can move the hand after the original target.
In round 3 of combat the Sorcerer moves 80ft away from their original casting point.
Again it seems pretty clear that if the original target has not moved in the round yet the Sorcerer can command the hand to grasp it.
- If the target the hand is following moves another 10ft away (so it's now 40ft away from the original casting point), can the Sorcerer command the hand to move after it again?
- If instead the target moves 30ft closer to the Sorcerer (so it is within 0ft of the original casting point, but 80ft away from the Sorcerer's current position) can the Sorcerer command it to follow in the same way as in round 1?
- Finally, if instead the target moves 80ft in the direction the Sorcerer moved (so they are now 50ft away from the original casting point and 30ft away from the sorcerer). Can my sorcerer make the hand move to be beside the target?
The essence of this question is does the "range" in which the hand can move shift with the caster, or shift with the hand, or remain defined based on the original casting point?
