Between the Filaments

As part of casting this spell, you create 4 equidistant medium-sized spirals of void energy within 5 ft. of yourself. At the end of your turn or whenever you would take damage, these spirals move 10 ft. opposite of one another. When a creature other than you starts or ends its turn within the area without a friendly creature within 5 ft. of it, it gains 1 stack of Sinking. Additionally whenever a creature takes Cold damage within the area, it's moved 5 ft. in a direction of your choosing. At the start of a hostile creatures turn or upon entering the area for the first time on a turn (expansion counts as entering the area), the creature must succeed on a Constitution saving throw or take 1d10 cold damage.

Friendly creatures cannot be within 5 ft. of you for the duration of this casting; if a friendly creature would start or end its turn within 5 ft. of you it's automatically shunted 15 ft. away from you. Once this spell ends, all creatures of your choosing within the are created by the spirals must succeed on a Strength saving throw or be pulled towards you.

Note: Sinking is a Status effect that works as follows. Sinking is a stacking status effect, when a creature with a count of Sinking makes an attack roll, ability check, or saving throw with disadvantage and misses their attack or fails their saving throw, they take an additional amount of damage equal to their Sinking count whenever they miss an attack roll or fail an ability check or saving throw and their maximum hit points are reduced by the amount of damage taken. Additionally a creature within Sinking has a penalty to hit when making an attack with disadvantage equal to their current Sinking count. When a hostile creature that the afflicted creature can see is reduced to 0 hit points, all stacks of Sinking are removed.
