BATSUIT
Beginning 6th level, the Batman begins to build a suit of armor for himself. The armor will always be painted black and fashioned with bat symbols throughout. This armor is equivalent to Medium armor (Hide, Chain, Scale, Breasplate, or Half Plate), and the Batman is immediately proficient with this Batsuit (even though he is not proficient with traditional Medium Armor).
When worn, the Batman gains a bonus to his Intimidation checks equal to half his Batman level. Furthermore, when wearing the Batsuit, the Batman's Dex modifer is maxed at 4 (rather than 2 of traditional Medium Armor), and would not gain Stealth disadvantage when wearing a Scale or Half Plate version of the Batsuit.
The Batsuit will also have different compartments (like the Utility Belt) which acts like an extra 30 slots for BAT ITEMS.
If the Batman has constructed a GRAPPLING HOOK, he may attach it to the Batsuit and use it even if he has no hands free.
Constructing the Batsuit must be done by the Batman himself (he won't outsource), requires access to a forge, takes x2 longer to construct than a normal piece of armor and costs x3 more than a normal.

I'll add it to the doc and upload a new pdf next week with this addition.
