Ethereal Chainblade

This spell conjures an ethereal chain with a razor-sharp blade at its end. The caster can use this chainblade in various ways:

1. Grapple (Action): As an action, the caster can use the chainblade to make a ranged grapple attempt. The target must make a Strength saving throw against the caster's spell save DC. On a failed save, the target is grappled.

2. Attack (Action): The caster can use the chainblade to make a melee attack against a target within range. The attack uses the caster's spellcasting ability for the attack roll and deals 2d6 force damage on a hit.

3. Restrain (Bonus Action): If the caster has successfully grappled a target, they can use a bonus action to tighten the ethereal chains, restraining the grappled target. The restrained target can attempt to break free on its turn, repeating the Strength saving throw.

4. Swing Attack (Action): The caster can make a sweeping motion with the chainblade, attacking all creatures in a 30-foot cone. Each target in the cone must make a Dexterity saving throw against the caster's spell save DC, taking 4d8 force damage on a failed save or half as much on a successful one.

Dismissal: The ethereal chainblade can be dismissed as a free action by the caster.
