Virtuoso's Magnum Opus

The world goes silent as you set the stage for your grand finale.

Your currently equipped revolver is imbued with suspense of your act to reveal your masterpiece. The revolver is transmuted into a wholly new weapon, the Curtain Call, and is granted the range of 400ft. 

The power of the sniper limits your movement and gives you a variation of the Restrained effect, everything stays the same but you don't have disadvantage to attack rolls, so set the stage for your work.

The sniper deals 4d6 piercing damage and on the forth shot you have an guaranteed crit. The forth shot has an additional affect of dealing 4 piercing damage for every 5 missing hit points on the target.

The spell ends when you use the fourth shot or when concentration ends. When it ends, the revolver used will melt down from the power of the Magnum Opus. If the revolver used was the Whisper, it reverts to it's original self and is fully loaded

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the spell use a dice that is a tier higher for each spell slot level.
