I've seen the debate on whether Mage Hand can be used without being seen or being cast in an area that cannot be seen by the caster, but my question is can you feel through the mage hand?

For example, a Mage Hand is cast and the caster has the mage hand travel around the corner to a shelf to grab a specific object? I've read that some DM's rule this as a Sleight Of Hand check with a blindness condition and thus disadvantage but that is assuming you can feel what the mage hand is grasping? Heck, if you can't feel the mage hand, you wouldn't even know if you were holding something in the mage hand without seeing it.

Obviously this ties in to being able to only use Mage Hand if you can see what you are manipulating. I love the flexibility of the spell and the imaginative ways it can be used, but it's also a cantrip that can break the game if not properly defined.

No, mage hand has no ability to feel.

Spells do what they say they do.

The description of the mage hand cantrip says:

A spectral, floating hand appears at a point you choose within range. The hand lasts for the duration or until you dismiss it as an action. The hand vanishes if it is ever more than 30 feet away from you or if you cast this spell again.

You can use your action to control the hand. You can use the hand to manipulate an object, open an unlocked door or container, stow or retrieve an item from an open container, or pour the contents out of a vial. You can move the hand up to 30 feet each time you use it.

The hand can't attack, activate magic items, or carry more than 10 pounds.

The spell doesn't describe any sensory capabilities. Thus, it has none. The caster must rely on their own senses. (Anything beyond that is up to DM fiat.)

RAW - No, mage hand has no ability to feel.

Say it with me, "Spells do what they say they do."

Per the description of mage hand:

You can use your action to control the hand. You can use the hand to manipulate an object, open an unlocked door or container, stow or retrieve an item from an open container, or pour the contents out of a vial. You can move the hand up to 30 feet each time you use it.

The spell doesn't list any capabilities to feel.

However, RAP (Rules As Played) there has to be some tactile sensation.

Without senses, how would the caster know how much pressure to apply to the vial so it can be gripped without breaking? Or know that you have a firm grip on that door knob you're trying to open?

Specifically, the Arcane Trickster gains mage hand, and part of the additional tasks it can perform is:

• You can use thieves’ tools to pick locks and disarm traps at range.

It would be virtually impossible to pick locks without the tactile feedback of feeling the tumblers "tumble" and when there is resistance in the mechanisms.

As a matter of playing, I rule that the hand cannot feel (and thus relate back) things like hot, cold, pain, wet, or windy. But it can still transfer pressure to the caster.
