Dimensional Slash

you brandish a melee weapon in the casting of this spell, must be your pact weapon- make a melee attack roll against creatures within 5ft of the direction you intend to cast the spell in- if you hit they have disadvantage on the dexterity save for the spell

you unleash a giant arcane slash from your weapon in a 20ft tall 60ft long 5ft wide rectangle- creatures within the line make a dexterity saving throw or take 5d10 force damage, and are pulled to the middle of the slash and their speed is reduced to 0 creatures stuck have the restrained condition- additionally creatures in the ethereal plane are hit as the spell is multidimensional- during the duration of the spell the line appears as a distortion of space pulling creatures and objects to its center- any creatures that end their turn within 10ft of any point of the spell make a strength saving throw or be pulled towards it and take 5d10 force damage

to leave the slash while within a creature must use their action to make a strength check (athletics) against your spell save DC on a success they can move with half speed for that turn
