So one of my players wants to play an Astromech. I've read multiple threads but need advice on two things.
1) How do astromechs get up stairs without jet packs? Honestly, I don't want a player stuck because there are stairs between him and the exit while a group of bounty hunters is closing in.
2) The player has a Brawn of 1, and so a total Encumbrance Threshold of 6. Unfortunately, he wants an assortment of tools, add-ons (including a holdout blaster and flame projector) that his Enc value is 19. My question is, should backpack modifiers stack? I'm not sure if that really makes much sense but he needs inbuilt tools.
