Casting Time: 1 action or 1 reaction, when an ally you can hear within 30 feet casts this spell
Range: 60 feet
Components: V
Duration: Instantaneous
You speak a word of power that can overwhelm the mind of one creature you can see within range, leaving it dumbfounded. Your spell's hit point threshold is 120. If an ally within 30 feet of you can hear you and can cast this spell, it can do so as a reaction to aid you. The hit point threshold then increases by 80 for each ally that aids you in casting this spell, up to a maximum of three allies.
If the creature you choose has hit points equal to or less than the hit point threshold, it is stunned. Otherwise, the spell has no effect.
The stunned target must make a Constitution saving throw at the end of each of its turn. On a successful save, this stunning effect ends.
