Alejandro's Electric Pillar

When you cast this spell, you drive your blade into the ground. A tether of lighting travels from your weapon to your target, bursting up from beneath them in series of arcing chains.

The target must make a dexterity saving throw or be restrained by the electric chains. The target also takes 3d10 lightning damage on a failed save, or half as much on a successful one.

While restrained by this spell, the target takes 1d10 lightning damage at the start of each of its turns. It may then make a strength saving throw against your spell save DC to attempt to escape the chains.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the initial instance of damage of the spell increases by 1d10 for each slot level above 3rd.
