A tide of creeping pests erupts from the ground, nearby rocks, and even folds of your clothing to cover you in a seething mass. The chitinous horde shifts and scuttles to protect you from attacks. You gain 8 temporary hit points for the duration. While any of these temporary hit points remain you are considered to have half cover and grapple attempts against you have disadvantage. The spell will end immediately after you suffer any damage from an area effect regardless of how many points remain.
