Scorpion Cloak

Wondrous item, rare (requires attunement)

This speckled sandy-brown cloak grants you advantage on Dexterity (Acrobatics) and Dexterity (Stealth) ability checks in desert terrain, and you can move without impediment difficult terrain such as soft or shifting sand. You gain advantage on attack rolls against scorpions and have resistance to poison damage from such creatures. You gain advantage on checks made to escape a grapple from a scorpion.

During any round you do not move, you gain tremorsense in a 10-foot radius, or a 20-foot radius if you are prone. The radius of this tremorsense increases by 5 feet (10 feet if you are prone) each round that you remain motionless, up to a maximum of 30 feet (or 60 feet if you are prone). If you are prone in a desert environment, you do not have disadvantage on attack rolls and gain the ability to move at your full speed. Additionally, if you are prone, you can make a melee weapon attack with a lashing sting, dealing 1d6 piercing damage and can deal an additional 1d10 points of poison damage as a bonus action.

Epic Attunement. You can communicate with scorpions as if using speak with animals to converse with animals, and once per day can hold scorpions at bay as a bonus action each round. Any scorpions that come within 10 feet of you while you are repelling them in this way take 1d10 necrotic damage each round they are within range. Additionally, you have tremorsense in any environment up to 30 feet even while moving, though this is doubled to 60 feet if you are prone.
