What is in Legacy of Terror?
For six days, Sanctuary serves the terrors and rewards below. Every line is taken from Blizzard’s anniversary post — no invented drop rates, item tables, or build advice.
Diablo Clone every six hours
Face the Diablo Clone once every six hours on Hell difficulty only. It works like the current system: Diablo Clone replaces a Super Unique in Hell. During the event, the spawn is guaranteed once every six hours. For how Clone and Annihilus work outside this window, see the Diablo Clone guide.
Terrorized Zones in every zone
After defeating Baal in Normal, Nightmare, or Hell, that difficulty features simultaneous Terrorized Zones in all zones. This is the same Terrorized Zone system covered in Terror Zones Explained, pushed to every zone on a cleared difficulty for the event. Site pages may also say “terror zones”; this event post uses Blizzard’s “Terrorized Zones.”
Cow Portal in the Rogue Encampment
After defeating Baal on a difficulty level, go directly to the Rogue Encampment to enter a special Cow Portal that stays active for the whole event. No side trip to Tristram is required. When the event ends, the usual Cow Level path returns — see the Secret Cow Level guide.
100% Magic Find and 15% vendor discount
Enjoy 100% Magic Find and a 15% discount on all vendors. The discount includes Gamblers and works at all difficulty levels. For how Magic Find works after the buff expires, see the Magic Find guide.
Hell Bovine Minions
Slay monsters for a rare chance to reanimate them as Hell Bovine Minions. Blizzard states this is available at all difficulty levels and does not publish a numeric chance — none is invented here.
How Legacy of Terror ties to Season 16
The English anniversary post frames the event as six days of threats and perks “to launch your Season 16 Ladder experience.” The start time matches Ladder Season 16’s open: November 13, 2026, 5:00 p.m. PST. Full Season 16 schedule, Patch 3.4 item notes, stash rules, and the November 16 character-transfer cutoff live on the Season 16 start date page (sourced from the Season 16 announcement).
How to disable all-zone Terrorized Zones
Players who do not want every zone Terrorized can still turn that feature off:
- Use the Game Creation (gear) menu on the Character Select screen, or
- Disable it in the Lobby when creating a game
Blizzard states that doing so does not affect any other features of the Legacy of Terror event — Clone timer, Cow Portal, Magic Find, vendor discount, and Hell Bovine Minions still apply.
All schedule and perk lines on this page come from Blizzard’s Legacy of Terror announcements (EN + zh-TW). If a number or regional clock is not in those posts, it is not listed here.
