Mage Hand Legerdemain

Mage Hand Legerdemain is an  Arcane Trickster passive feature. This ability enhances your Mage Hand, allowing it to carry out additional tasks.

Description

Your mage hand can stow away or retrieve objects carried by other creatures and use Thieves' Tools at range.

• There is no longer a time limit, and the Mage Hand lasts forever until destroyed or dismissed.
• The Mage Hand is now permanently Invisible.

Condition: Invisible

 Invisible

• Has Advantage on Attack rolls and imposes Disadvantage on enemy Attack Rolls.

Invisibility ends early if the invisible entity attacks, casts another spell, interacts with an object, takes an action or bonus action, or is damaged.

How to learn

Classes:

• Class level 3: Arcane Trickster

Notes

• Despite the description, the mage hand doesn't actually seem to be able to use Thieves' Tools to pick locks as of patch 6 / hotfix 20.
• This is probably the best tool to scout safely, as long are there are no creature with  See Invisibility, which is fairly rare. One can scout an entire area thanks to the Mage Hand's  Fly which makes it able to go to places otherwise very difficult to reach, as long as one can make the camera see the ground level of that place.
• An effective use of the hand is to use it to throw objects or potions in battle. Dropping an item on the ground for the hand to throw does not cost an action.
