True Assault (Revised)

You extend your hand and point a finger at a target in range. Your magic grants you insight into the target’s defenses. Until the spell ends, you deal an extra 1d4 (weapon type) damage to the first strike a turn with a weapon attack, and you have advantage on all attacks against your target until the spell ends

At Higher Levels. When you cast this spell using a spell slot of 3rd or 4th level, your dmg dice increases to 1d6 and 1d8 respectably.
