Bring the Idol of the Snake is a side quest in Might and Magic VIII: Day of the Destroyer.
Hiss says he has found an ancient spell that he thinks can send the volcano outside the Dagger Wound Islands back into the sea, but he needs the Idol of the Snake to complete the spell. He wants the party to enter the abandoned temple and retrieve the idol.
Walkthrough[]
To reach the abandoned temple, the party must complete the Bring Brekish Onefang's portal crystal to Fredrick Talimere quest, and then use the teleporters. They must then fight their way through the abandoned temple, a dungeon full of couatls and serpentmen.
The idol can be found in the last room before the exit. The floor is covered with red tiles, all of which except one is trapped. Head to the center of the room and stand next to the pillar. With their backs to the entrance, the party must then turn left and step on the closest red tile, which will open a wall panel near the entrance to the room.
Behind the panel is a trapped chest, and the idol is inside. The party can then bring it back to Hiss for the reward.
