Pendulum

are recurring traps in.

This unique trap can only be found in the Temple of Time on the first and eighth floor of the dungeon. It swings left to right in a continuous motion through a straight grove in the floor. It has a hole to shoot though with Arrows, which can be used to shoot down the active Beamos on the way to the boss room. The Pendulum's blade can be avoided by timing the moment of its swing in order to pass by it and avoid taking damage. They cannot be halted by statues that are controlled by the Dominion Rod, nor can they be destroyed by any means.
