Turn 1 : Summoning roar of Ian'g'illan: 2 Tanarukk with blindsight 15 feet and resistance to Acid and Psychic Damage appear in two empty spaces 30 feet of her : their initiative is zero. Then each creature of Sisthraksia's choice that is within 120 feet of her and aware of her must succeed on a DC 16 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to this effect and the Terror Attack's effect for the next 24 hours.
Turn 2 : Terror Attack Sisthraksia grabs a vulnerable target. She moves and attempts to grab a medium or smaller target. Wether she succeeds or not, she can finish her movement, dragging her target with her. Every creature hostile to Sisthraksia must make a DC 16 Wisdom saving throw or become frightened for 1 minute. If a creature's saving throw is successful or the effect ends for it, the creature is immune to this effect and the Summoning Roar's effect for the next 24 hours.
