Festival of Life

Mistvale's festival during which a resurrection is performed. Since the 1220's this celebration has been unobserved, but at Prince Virion's insistence, the festival is back on, and the city is thrilled. This year it is on the 19th of Kythorn, and they are resurrecting Vahn Relarius.
  Dendybar or his mages will have to make three DC18 arcana checks to complete the resurrection. Each check requires an action to complete, and while the check can be attempted multiple times per round, only 1 success can be recorded. Dendybar has advantage on the arcana checks. Meanwhile, the players must destroy 3 necromantic constructs (AC 10, 20 HP, vulnerable to bludgeoning damage, immune to necrotic and poison damage) spread across the ritual room. Each construct destroyed increases the number of successes needed to complete the ritual by 1, and once all three are destroyed the ritual fails outright.
  The Mistvale Rebels will attempt to stop the resurrection from happening, but they will fail if the party does not intervene. Only their leader Mitris will survive, but he will be publicly executed on the 22nd of Kythorn.
  If they side with the rebels and fail to stop the resurrection, they will be thrown into jail.
  Succeeding to stop the resurrection will deal 8d12+10 damage (DC15 wis save) to everyone within 20ft of Vahn's body. and they are knocked prone.
  If it fails and Virion is killed, Dendybar will report his loss to the Arcane Brotherhood
