Drain Life (G)

You weaken a foe by lowering its max hit points. Choose one creature that you see within range to make a Constitution save. On a failure, 2d8 + your SAM worth of hit points are subtracted from its max hit points until it finishes a long rest. If this effect reduces the target's total hit points to 0, it dies.

At Higher Levels. When you cast this spell using a slot of 3rd or higher, you target one extra creature for each level above 2nd.
