The inventory screen has been finalized. Kilgazar will have a limited inventory, but this shouldn't be too cumbersome to the player. There will never be a need to do any sort of heavy inventory management or stacking or anything like that.
The new design reinforces the player ability icons that are also found at the bottom of the screen (melee, projectile, magic, and defense). When you hover over an item in your inventory or an equipped item (upper right), you will see how that item affects your player's abilities. An item can give different abilities and different amounts of abilities to the different classes. A warrior is able to use a sword better than a magician or rogue, a rogue can use a bow better, and the magician can use magical items better. A magical staff would boost a magician's magical abilities a good deal, but for a warrior would get only a small boost and it would serve as a poor melee weapon.
