Enialeigh's Arrow of Astral Chains (Arteria)

You shoot an ethereal arrow that manifests chains upon hitting a target. Make a ranged attack against a creature within range. On a hit, the creature takes 6d10 force damage, and ethereal chains wrap around them. The target is restrained for the duration. While restrained, the creature takes an additional 2d10 psychic damage at the start of each of its turns.

At the end of each of its turns, the target can make a Strength saving throw. On a success, the chains shatter, ending the effect. If the creature is on the Ethereal Plane, the spell fails.

At Higher Levels: When you cast this spell using a spell slot of 7th level or higher, the damage increases by 1d10 for each slot level above 6th.
