Other additions to the game are a sign of things to come in the future editions of Dungeon Siege. The new pack animal is more than a walking backpack; it can fight and defend itself. There is a traditional backpack in the game that increases inventory 54%. New spells include orb spells that revolve around the caster and magical land mines that explode when touched by enemies, greatly increasing the power and strategy of spellcasters. In addition to the new lands to explore, Dungeon Siege: Legends of Aranna also has more than one hundred new weapons and monsters, more than seventy new spells, and never before seen non-player characters.
