Edeneth's Spatial Rend

You conjure a blade of pure force by folding space into an ultra-fine edge. Make a melee spell attack with a range of 10ft. On a hit, target takes 5d10 force damage. Hit or miss, all creatures in a 30 ft cone from the target, aimed directly in front of you, must make a Dexterity saving throw taking half of the damage dealt to the initial target and are pushed up to 15ft or no damage and are not pushed on a success.

This spell's 10ft reach is not added to a weapon which already has a 10ft reach. This spell cannot be cast with an arcane focus; a magical melee weapon is required as part of the spell.
