Carlee's Storm of the Right-Legged

You point at a target within range, and a swirling rift of inky darkness opens above them. From the void, hundreds of skittering spiders rain down, biting and crawling over anything in the area.

• When a creature starts its turn in the affected area (10-foot radius), or enters it for the first time on a turn, it must make a Dexterity saving throw. On a failure, it takes 3d6 piercing damage and is restrained by the swarm until the start of its next turn.
• A creature restrained by the spiders can use its action to make a Strength (Athletics) check against your spell save DC, freeing itself on a success.
• The area is difficult terrain for the duration due to the crawling mass of spiders.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 3rd.
