Press [I] and your whole bag opens as one clean, unified grid. No more juggling separate menus - potions, alchemy ingredients, trinkets, gold, and your equipment all live side by side in a single 30-case inventory. Every room comes with your own Personal Chest - a private stash that only you can open. Walk up to it in your room, press Use, and the lid swings open onto a clean two-pane storage screen: your carried inventory on the left, your stored items on the right.
You will find bunch of useful items here.Pick one notebook at The Bazaar and you'll carry a writable notebook everywhere you go.Also, Ember Dust, useful to use Ember Gates. It's not free to travel anymore ;)
