If you were lucky enough to get a key to enter Echoing Hatred you might have noticed certain mysterious messages hidden within. After solving their riddle, u/jordani97 on Reddit, discovered a secret cosmetic Portal skin as a reward.
The four secret messages correspond with the four Shrines located inside Echoing Hatred and when each one should be activated.
The first message refers to the Immunity Shrine, which should be activated between Tiers 1-9.
The second message refers to the Artillery Shrine, which should be activated between Tiers 10-14.
The third message refers to the Lethal Shrine, which should be activated between Tiers 15-19.
And lastly, the fourth message refers to the Channeling Shrine, which should be activated between Tiers 20-24.
After this is done, several shadowy Goblins will appear, and when killed, will award the Only The Mad Run Free achievement as well as the Howling Mouth of Madness portal skin.
