Diablo II: Resurrected Legacy of Terror: Event Dates and How Terror Zones Change

Legacy of Terror begins in Diablo II: Resurrected on November 13 at 5 p.m. PST, alongside the start of Ladder Season 16. For six days, players who have beaten Baal can take a portal directly to the Secret Cow Level, and every eligible area can be Terrorized at once. Blizzard also announced a recurring Diablo Clone spawn in Hell, a Magic Find bonus and cheaper purchases from vendors.

Blizzard says both Ladder and Non-Ladder players can take part. That gives returning players a choice on opening night. Bring an established character with the relevant difficulty cleared to start farming, or roll a fresh Ladder character and work through the campaign first.

When Legacy of Terror starts and ends

The dates in Blizzard’s anniversary announcement use Pacific time. The event crosses midnight in Europe at both ends, which matters if you plan to use the last evening to clear a difficulty or finish a few Cow Level runs. Ladder Season 16 starts at the same time, but the event end date applies to Legacy of Terror. The Season 16 announcement lists its own rollover rules and does not give November 19 as the season end.

What beating Baal unlocks

Baal’s defeat is checked separately for each difficulty. If you have cleared Nightmare but are still working through Hell, you can use the event’s Nightmare Terror Zones and special Cow Portal while you finish the Hell campaign. If you want to farm Hell Terror Zones or enter the Hell Cow Portal, finish Hell Baal first.

Under the event rules, all eligible areas of a cleared difficulty can be Terrorized simultaneously. That lets you pick a familiar route that suits your build instead of changing to an area with awkward immunities or a long approach. Pick somewhere you can clear efficiently, especially if you are still assembling gear at the start of Ladder.

The all-zone rule is optional. Blizzard says you can disable it from the game creation gear menu on the character selection screen or in the lobby. The other anniversary bonuses still apply if you turn that option off.

Where to find the anniversary Cow Portal

After clearing Baal on the difficulty you want to play, return to the Rogue Encampment in Act I. The special Cow Portal is available there during the event. The normal trip to Tristram for Wirt’s Leg is unnecessary when you use this event portal.

For a fresh character, the route is therefore simple: clear Baal, start or join a game on that cleared difficulty, and go to Act I. If you switch to a higher difficulty before completing its campaign, go back to the cleared difficulty to use its portal. This is a temporary shortcut announced for Legacy of Terror, so plan around the event end time if the portal is your main reason for returning.

Diablo Clone and the other bonuses

Blizzard says the Diablo Clone will spawn once every six hours during the event in Hell. The encounter uses the existing rule where the Clone replaces a Super Unique monster. The anniversary post gives a cadence, so check what the game reports during your session before committing to a specific farming window. Bring a character ready for a Hell encounter if the Clone is your target.

The event grants 100% Magic Find and a 15% vendor discount. The discount includes gambling and applies across the difficulties. If you already planned to spend a gold reserve on gambling, do it before the discount ends. Monsters can also rarely return as Hell Bovine allies after being slain. That effect is available across the difficulties and can show up during ordinary combat.

What to prepare for opening night

For a quick start, check your intended character’s Baal completion and keep a clear route in mind. If your priority is Cows, go straight to the Rogue Encampment once the event is active. If you are starting a new Ladder character, use the campaign as your first milestone and check each difficulty’s unlocks as you go. Hell matters for the Clone, while the Cow Portal and Terror Zones offer ways to take part on cleared lower difficulties too.
