Universal Sense

Universal Sense (万能感知) is an Extra Skill and one of the Intrinsic Skills of True Dragons.

Abilities
Universal Sense allows for the perception of nearly all things within a wide radus. It is an enhanced version of Magic Sense with superior sensory capabilities, allowing the user to perceive not only light and sound, but smell and heat in an extremely wide radius.

This ability allowed Rimuru to detect Gazel Dwargo and his Pegasus Knights approaching Tempest way before a spy like Souei who is known for his superior ability to gather information.
