A bigger satchel: 40 slots (was 28), and coins now live in their own pouch so they never take a slot.
Packs. A new pack slot for 8 packs, from the Rucksack (+8 slots) to the Aether Haversack (+24), plus the Bag of Whispers from the Hollow Echo. Sew them with Tailoring or buy the early ones in shops. Your pack shows on your character's back.
Weight. Every item has a weight, and how much you can carry grows with Might, Vitality, Agility and your pack. Worn gear counts half. Carry too much and you slow down: Burdened (over 100%) costs speed and stamina recovery, Overburdened (over 125%) stops sprinting, jumping and dodging, and Crushed (over 150%) stops you picking up, gathering or crafting anything heavier. The Draught of Oak and Lightfoot Draught help. A chip on the HUD and weight bars show where you stand.
A better satchel window: search, category filters, sort, compact, hide junk, slot size, multi-select, slot locks and a Packs & Carry tab.
A bigger bank: 480 slots across 6 tabs you can rename, with search across tabs, quick-stack and deposit-all per tab.
Your existing items carry over: anything that no longer fits your satchel goes to your bank.
