We wanted to take a moment to clarify how the Sinister Calling achievement works for Hallow’s End. The text says that both a Hallowed Helm and a Sinister Squashling pet need to be “obtained” for the achievement to be complete. More specifically, the pet needs to be learned and become part of your pet spell book for that part to be complete. The Hallowed Helm on the other hand needs to be looted by the character to fulfill that aspect of the achievement.

We apologize for any confusion in this matter and hope you enjoy the rest of Hallow’s End!
