Your inventory contains all the items your character has picked up. You can open it by pressing your "I" key, or by clicking "Items" in the Status Window.
The inventory is divided into three "sections" that you can click to show the items you have:
- Usable (displayed as an apple and a carrot): Items you can eat, drink, or otherwise use.
- Equipment (displayed as a blue shield): Items that you can wear.
- Other (displayed as a bag of gold): Anything else - these items might be used for quests, as ingredients for alchemy, cooking, or arrow crafting, or can simply be sold to shopkeepers for some silver.
There are two limits that affect how much you can carry: Weight and Bag Space. Both can be increased by equipping better bags. In addition, your weight limit can be increased by putting stat points into your strength stat.
