Icy room with 4 buttons

Slide across the room to stand on the four buttons. Obstacles can be used and it is possible to slide diagonally. We provide Runescape powerleveling for you.

Seeker sentinel

The goal is to get through the room without being seen. The seekers patrolling the room can be hit when not facing you, temporarily immobilizing them. There is also a seeker in the middle which turns around slowly. There are four walls which can be used to hide from the seekers. Simply wait until no seekers are facing you and hit the seeker patrolling nearby and then run to the next wall. Repeat this until you reach the door needed.
