RPG I: The Necromancer's Revenge

Cast Fireball on the Druid, then close the distance (if the Druid doesn't die).

The Druid died, but the Dryad protected the Half-Orc, and he took advantage of this to deal -15 damage to you. However, the Archdevil also dealt -40 damage to him, but the Unicorns gored the Archdevil. The Archdruid is casting an expulsion spell, but it doesn't help. What now?
