Why not have someone run around and hand stuff off?

Clockwork Familiar Feat 6

Inventor
Prerequisites construct innovation

---

You’ve learned to build big, now you tinker with the small. You build a clockwork creature that is the size of a house cat. It has AC 10, +0 to all saves, moves at 30 feet per round, can crawl up walls, and 1 hp. Each turn you can give the creature one free action to move and grab things up to 1 bulk. It can also hand things off to other character and even administer potions to other characters. If killed, it can be repaired as normal. It can not function outside of your sight as it is unintelligent and only responds to commands.
