Adamant Barrage

 Upon casting this spell, the striking surface of a melee weapon being wielded by the Spellcaster becomes encrusted with a thick layer of diamond like Crystals. On the swing of the next melee attack, in place of the normal weapon damage, the Crystals instead explode outward in a 40ft cone of Shards in front of the you dealing (3d6)+SM Piercing Damage and the spell ends. Targets within the cone must make a DEX Save Throw. On a Fail targets take full Damage. On a successful save targets take half Damage.

When casting using a spell slot of 4th level or higher, increase damage by 1d6 for each spell level above 3rd level.
