Walk in the Park
From Diablo Wiki
Walk in the Park is triggered when one opens a chest in a park sometimes found in the Westmarch Commons in Act V. The gates of the park close and are locked and the only way out is to kill the reapers (Revenant Archers and Revenant Soldiers) that attack you. There are two waves of reaper attacks. Defeating the first one unlocks the inner gates and defeating the second one unlocks the outer gates.
The chest contains the "Urzael's Trap" Lore Book.
