Worshipper – “Agral’s Decision” [Campaign 2, Mission 5]

The mission is very simple. Reach the island where the emerald dragons are, and behind them, the altar of magic. Defeat the dragons with chaos magic. Hopefully, you have it. At the altar, take the ship summoning spell. Summon the ship. Sail to the cartographer. Buy a map. Sail to the island to the right of Tieru (Tieru is on the island with the bridge. It's in the middle of the map, you'll find it). There, defeat the druids and go through the tunnels to Tieru's island. Defeat the dragons easily with chaos magic and 15 karats (they are on one of the small islands). Watch the cutscene. (Tieru and Agrael are awesome!)
Hero difficulty.
