Briars of Punishment

You coat the ground in your own blood, causing a trail of thorns to shoot forth along the ground towards a target within range. The trail can move along any connected surfaces to reach its target but will miss automatically if the target is more than 5 feet from the nearest connected surface (such as the ground or a wall). You take 1d8 necrotic damage, which can’t be reduced in any way, then make a ranged spell attack. On a hit, the target takes 4d6 piercing damage as a pillar of thorns impales them.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can send forth an additional trail of thorns to the same target or another within range, taking necrotic damage for each trail separately. If you use a slot of 5th level or higher you can send two additional trails. If you use a slot of 7th level or higher you can send three additional trails. If you use a 9th level spell slot you can send four additional trails. Using a spell slot of 5th level or higher grants an additional effect: each creature hit by two or more trails of thorns must make a Constitution saving throw. On a failed save, the creature takes 2d12 necrotic damage at the end of its next turn.
