AD&D Let's Discuss Vision and Movement for a moment..

Infravision allows creatures to see in the infrared spectrum, useful for nocturnal and underground beings. Different light sources, such as torches and magic weapons, provide illumination necessary for activities in low-light environments. Infravision can be hindered by light sources and extreme temperatures. Ultravision enables sight in the ultraviolet spectrum, while silent and invisible movement techniques enhance stealth in various situations. Highlights -🔦 Infravision: Enables seeing heat radiation; warm objects appear bright. Light Sources: Various devices like torches and magic weapons illuminate areas differently. Ultravision: Allows sight in ultraviolet spectrum, aiding visibility in darkness. Silent Movement: Thieves can move quietly, improving chances of surprise. Invisible Movement: Magic can render characters invisible, but light sources expose them. Temperature Effects: Light can spoil infravision; great heat affects visibility. Stealth Mechanics: Characters must manage light and sound to remain unseen
