So the Trickery Domain's first channel divinity is Invoke Duplicity, you make an illusion of yourself, and it says
For the duration, you can cast spells as though you were in the illusion's space, but you must use your own senses.
Now, I'm sure this is meant to be so that you can't just move the illusion somewhere that it can see a target that has full cover from you in order to attack them with a spell, but it brings into question whether it counts the sense of touch. Could a cleric use this as a way to heal allies with Cure Wounds up to 120 feet away? Or use Inflict Wounds on enemies in the same way?
