Similar to its contemporary
Realms of the Haunting,
Guardians of Destiny is a first-person
adventure game which, while featuring occasional combat, revolves around the solving of puzzles. Like in most adventure games, the player can interact with objects and people by clicking on them, collect items into an inventory, and use items from their inventory on environmental objects. However, some puzzles also require the player to cast spells, use their melee attack, or drag objects and even enemy corpses into specific locations. Navigating through the environment also often involves
platforming challenges, some of which can be undertaken only in one specific form. The player character, Luther, has a curse which causes him to randomly change between three forms: human, lizard, and beast. Later in the game the player acquires spells which can be used to change form at will if in human or lizard form; once in beast form Luther must wait to change randomly back to human form, since the beast cannot cast spells. The lizard form is small, allowing it to enter tunnels inaccessible to other forms, but preventing it from crossing even shallow streams of water without drowning. It can run faster and cast spells more easily than other forms. The beast form is tall and heavy, such that it can make only mild jumps, but in some places its size allows it to step across gaps that the other two forms would have to jump over, wade across the deepest body of water, it's also immune to poison and very strong. The human form is an average of the other two in most respects, but is the only form which can equip weapons or armor. Combat works similarly to
The Throne of Chaos, except that the player's party consists of just one character, and most enemies will not attack the player character unless provoked. Luther can use a melee attack, fire a bow at range, use items, and cast spells at four different levels. Each spell has a fifth level which is only usable if Luther consumes an ancient stone or has acquired the Mantle of the Ancients, which occurs at a set point near the end of the game. Spells draw on a limited pool of
magic points, which, like Luther's health, is gradually recovered over time. ==Plot==
