The Destiny 2 Mida Multi-Tool is very similar to the Destiny 1 iteration in all of the ways that made players like it so much originally.
The Mida Multi-Tool is a great little exotic Scout Rifle with some very useful perks including a boost to your movement speed.
This quest unfolds over the course of a number of steps, and waiting for you at the end will be the Mida Multi-Tool.
The final quest Banshee-44 will give you in order to get your hands on the Mida Multi-Tool exotic scout rifle is called The Fall Will Kill You, and the quest objective here is appropriate for the name.
