>>39671838>Pick itemYes, just one, the held one, its a scout and gather function for rare items where the trainer cant go, like in LGPE
>Get in fightsYes, with wild pokemon like always. Trainers will only battle you if you talk to them. Not recomendable since you are single pokemon against a team.
>how it doing remotely?Lorewise the trainer just give the order to explore and collect rare items/berries
Also you can only use this feature if you have minimum 2 non-fainted pokemon. If the exploring pokemon faints you sends your other pokemon on rescue. It fades to a cutscene then theres your fainted pokemom in your team and the rescuer is with half of its initial HP/PP
