Tonal Resonator

A Tonal Resonator was a device created by the Dwemer. They were used as stationary gate-openers in which one had to use a bow and arrow, or a Destruction spell, and shoot one of the handles on the Resonator so that it would spin up or down, which would open the nearest gate or door.

Fahlbtharz Puzzle
In the Dwemer ruin of Fahlbtharz, located on Solstheim, contains several Tonal Resonators throughout the ruin. Near the end of the journey towards the Great Hall, are six Tonal Resonators in a large room that represent a very complex puzzle that opens a gate leading to the Great Hall. Though there are six Tonal Resonators, only 20 lights need to be lit, in which the far left Tonal Resonator needs to be shot at 3 times, the middle left one 4 times, and the middle right one 13 times.

Number of lights lit by each valve:
 * Far left = 3
 * Middle left = 4
 * Left closest to center = 6
 * Right closest to center = 9
 * Middle right = 13
 * Far right = 18
