Starting at 2nd level, you have a few gizmos that whir around helping you and your allies. Choose 3 from the following:

Shield Friend - Adds +1 to the AC of whoever is closest to it.

Helping Hand - Assists you in completing a task. Whenever combat begins, you have advantage on the first attack you make. Reloader - Reloads weapons for the closest ally. (DC 10 dexterity check)

Grappler - Wrestles the nearest enemy to the ground. (DC 15 strength check to break free)

Scout - Quickly moves ahead of the party to relay through signals and beeps what it sees.

Searcher - Makes investigation checks to find hidden items and loot (Investigation is equal to yours)

These helpers requires batteries to operate; one battery will give them 1d20+4 hours of juice. During a short rest you can reassemble one to change their role. There can be multiple of the same style deployed at once.
