Quick answer: D2R Ladder Season 16 starts Friday, November 13, 2026 at 5:00 p.m. PST in North America — November 14, 9:00 a.m. CST in Asia. Season 15 ends Monday, November 9 at 11:00 a.m. PST; Patch 3.4 begins rolling out that same day. Patch 3.4 is a Reign of the Warlock–only item pass (Online Ladder + Offline), not a new-act content drop.

Ladder modes in Season 16

Season 16 keeps the same four ladder modes as previous seasons:

What happens when Season 15 ends?

The reset rules follow the established pattern, restated in the Season 16 post:

Character conversion cutoff — November 16

The Season 16 announcement also tightens Expansion → Reign of the Warlock transfers:

If you still have Online Expansion characters you want on ROTW, convert them before November 16. Shared stash does not travel with the character — ferry items first. Full checklist: Character Transfer Deadline.

Patch 3.4 overview (Reign of the Warlock only)

Patch 3.4 ships with Season 16. Blizzard is explicit about scope:

Items now available in Online Non-Ladder

Previously updated Ladder-only items become available in Online Non-Ladder with the new season (RotW only):

These are the Season 15–era RotW ladder buffs rotating into Non-Ladder — the same rotation pattern as prior seasons.

Item updates in Online Ladder and Offline

Every change below is quoted from Blizzard’s Patch 3.4 notes (Online Ladder + Offline, RotW only):

Full post-patch rolls are live on the uniques, sets, and runewords databases (Season 16 / 3.4 badges). Notable early-ladder / mid-game lines: The Atlantean drops to required level 35 with Zeal ranks; Lava Gout becomes a Cannot Be Frozen glove; Veil of Steel gains +2 all skills plus physical and magic mitigation; Eternity now fits five-socket bows/crossbows as well as melee.

Bug fixes in Patch 3.4

Blizzard lists the following fixes with the season patch:

How to prepare before Season 16 starts

  1. Withdraw Season 14 Past / Withdraw Only tabs before November 9 — those older tabs are deleted when Season 15 ends.
  2. Convert Online Expansion → ROTW characters you still care about before November 16 (ferry shared stash first).
  3. Pick a starter build that levels on no gear — Warlock leveling is one RotW option; classic seven-class starters still work.
  4. Map early runewords with runewords by level (Stealth, Spirit, Insight, and so on).
  5. Block launch weekend around your region’s start time in the table above.
  6. Know where you will trade once the fresh economy settles — see D2R trading sites.
