Murazor's Vision

A self-enchantment which alters the caster's visual perception so that he can only "see" infrared radiation. The caster can perceive the approximate temperature of the heat source and its approximate size. He can distinguish temperature differences of 10°C or more. The caster has great difficulty perceiving detail in objects of uniform temperature, and with the basic spell, he is unable to differentiate between a single large heat source and multiple smaller heat sources of the same temperature.

The caster's range of sight is extended greatly, allowing him to perceive the following, provided they are within line-of-sight:
