Belts: Couldn't they also expand the inventory?

[Zylx]

As you can see above, there are quite a few belts that are designed to hold things in them to expand the wearer's carrying capacity. Police officers, maintenence/construction workers, batman, even some everyday people use these to carry wallets/phones in little pouches on their belts.

As STS has said, these belts are designed specifically to add additional stats.. but couldn't they also be more unique than a magical strip of leather that sits at your hip?

These belts could be preset with additional inventory pouches, or they could be expandable through some upgrade quests.

The regular inventory cap without a belt would be 500 as before (you still cant buy inventory slots past that), but if you equip a belt with +25 inv slots, it could raise your inventory capacity up to 525, and when unequiped, it would lower back down to 500.

If you unequip a belt and your number of items exceeds your inventory capacity, you will keep the items, but you would not be able to trade or enter any maps until you either re-equip the belt or delete the extra items.

I'm not sure if the belts are multi-rarity, or if they are only exclusive to certain rarities, but considering the former if values are preset:

Common: +1 inv slot
Rare: +5 inv slots
Epic: +10 inv slots
Legendary: +15 inv slots
Mythic: +25 inv slots
Arcane: +50 inv slots

(Values are negotiable)
