You create a spectral hand to siphon the life force from a creature to bolster yourself. Make a ranged spell against against the target within range that you can see. On a hit, the target creature takes 1d8 necrotic damage. If you hit a creature with this spell, that is not a construct or undead, you gain temporary hit points equal to your proficiency modifier until the start of your next turn. This spell counts as eldritch blast for any option or enhancement that applies to the eldritch blast spell such as the warlock's eldritch invocations.

The spell creates more than one spectral hands when you reach higher levels: two at 5th level, three at 11th level, and four at 17th level. You can direct the spectral hands at the same target or at different ones. Make a separate attack roll for each spectral hand.
