Bloody Fissure, Thundering Thrust

You dart forward, propelled my magical energy to pierce into your enemy's unguarded defenses faster than the eye can see, and through their form. 

You deal 3d6 magical piercing damage on a hit. And can move up to 10 extra feet when using this spell to reach your target. 
You use a weapon attack,  and deal the damage as additional.

You deal 1d6 extra damage if you use this spell within the first 3 rounds of combat.

At higher levels, you deal an extra 1d6 on hit, and another extra 1d6 if used within 3 rounds of starting combat.
