Shriek of the Byakhee

4th-level conjuration

Casting Time: 1 action

Range: 60 feet

Components: V, S

Duration: Concentration, up to 1 minute

You utter an unearthly shriek, signaling across space and time, summoning one byakhee that appears in an unoccupied space that you can see within range. A summoned byakhee disappears when it drops to 0 hit points or when the spell ends. The byakhee must be one known to you or which you have researched extensively, which generally requires 10 days and a successful Intelligence (Arcana) or Wisdom (Yog-Sothothery) check against DC 15.

The byakhee makes a Charisma saving throw when it arrives. On a failed save, it is indifferent toward you and hostile toward all other creatures. On a successful save, it is hostile to all creatures, including you. Roll initiative for the byakhee, which has its own turns. The byakhee pursues and attacks the nearest non-byakhee to the best of its ability. The byakhee cannot use its own Shriek ability.

When you cease concentrating, the spell does not end immediately, but lasts 1d4 rounds, after which the byakhee vanishes at the start of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 7th or 8th level, you also summon a second byakhee. When you cast this spell using a spell slot of 9th level, you also summon a third byakhee.
