Dolas' Spectral Spears

Focusing on the souls of warriors long dead and buried, you summon 3 spectral spears from fragments of their souls. The spears can target different or the same enemy. Make a ranged spell attack for each. Each does 1 d10 necrotic damage on a hit, and if all 3 hit the target takes an extra d6 psychic damage. If the target is below half health the 1 d10 becomes 1 d12 and the extra d6 becomes a d8.
