Arcane Firearm Enhanced Ariki's Blast Wave

A wave of fiery force burst out from you. Each creature in a 15-foot cube originating from you must make a Constitution saving throw. On a failed save, a creature takes 1d8 fire damage as well as 1d8 force damage and is pushed 10 feet away from you. On a successful save, the creature takes half as much damage and isn't pushed.  ~ At 5th level you can use your arcane firearm as a spellcasting focus for your artificer spells. When you cast an artificer spell through the firearm, you gain (1d8) to one of the spell’s damage rolls.

In addition, unsecured objects that are completely within the area of effect are automatically pushed 10 feet away from you by the spell's effect, and the spell emits a explosive roar audible out to 150 feet. All flammable objects not carried of worn within the spells area of effect immediately ignite.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 force damage for each slot level above 1st.
