Reckenstuph the Ruinator was a powerful wizard with an exceptional degree of arcane knowledge and ability. The mage dabbled in many different areas but focused on creating spells of the utmost offensive and destructive forms. The reclusive enchanter worked in secret creating hundreds, some say thousands, of spells both powerful and mundane. It was said that all of these were recorded in a single spellbook. The wizard died at the hand of a most avarice student, using one of the wizard's own exceptionally powerful spells. The student sought to steal the book and use it for their own gain. However, the tome was never found and for many years remained lost to the world until...
With components in hand you speak an arcane phrase and a blue cone of deathly magical energy forms in front of you.
Each creature in a 30 foot cone must make a Wisdom saving throw. A target takes 1d10 psychic damage on a failed save or half as much on a succesful one.
On each of your turns for the duration you can use your action to deal 1d10 psychic damage to the target(s) automatically.The spell's damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10) and 17th level (4d10).
