You detect things that those with sight cannot, whether you're in complete darkness, deep in the dense fog, or dealing with invisible enemies. You can't read, discern colors, or perceive details that don't involve sound or odor. But when it comes to detecting a creature's presence, movement, and basic shape, blindsight can allow you to get it. You have advantage in Wisdom (perception) and Wisdom (intuition) rolls.

Echolocation: By hitting your blind cane, wooden staff or any object that emits sound and vibration on the ground, you can within a radius of 60ft detect the presence of creatures and magical objects that are within range. Creatures that don't want to be detected need to make a Dexterity save roll. (CD: 8 + your Proficiency Bonus + your Wisdom Modifier). Echolocation lasts for one round, each turn the creatures have to reroll.
