You send a pulse of psionic energy at a creature of your choice within range. The creature must make an intelligence saving throw or take 1d8 psychic damage. if the creature fails the saving throw by 3 or more, then increase the damage die to 1d10. 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 pulse when you reach higher levels: two pulses at 5th level, three pulses at 11th level, and four pulses at 17th level. You can direct the pulses at the same target or at different ones. Each creature must make a separate saving throw for each pulse.
