Quick answer: Patch 3.3 is a tuning patch, not a content patch: nine unique items and one set get buffed, previous ladder-only items open up to non-ladder, eight adjusted Reign of the Warlock runewords stay ladder-exclusive, Terror Zone rewards are retuned, and thirteen bugs are fixed. The ladder reset itself works the same as previous seasons.

Ladder reset rules for Season 15

The reset follows the established pattern, confirmed again in the official post. Season 14 ends Monday, August 17 at 11:00 AM PDT (August 18, 2:00 AM Taiwan time), Patch 3.3 rolls out that Tuesday, and the Season 15 ladder opens Saturday, August 22 — see our Season 15 start date page for the full regional timetable.

Ladder runeword rotation

As of the new season, previous ladder-only items become available in non-ladder — the standard end-of-season unlock. The exception is a set of eight Reign of the Warlock runewords that received balance adjustments this patch and therefore remain ladder-exclusive: Mania, Hysteria, Metamorphosis, Ground, Temper, Hearth, Cure and Bulwark. The restriction applies to Reign of the Warlock content only; Diablo II Classic and Lord of Destruction modes are unaffected.

For fresh-ladder runeword priorities, see runewords by level, and for the expansion's runeword list, the Infernal Edition runewords page.

Item changes: nine uniques and one set buffed

The patch's biggest item pass targets underused low- and mid-level uniques. Changed items are available on the ladder only:

None of these are endgame shake-ups — they are early-ladder quality-of-life buffs. The Angelic set's +1 all skills is the most ladder-relevant line: a full-set leveling character gets a real power bump in Normal and Nightmare.

Terror Zone and Herald tuning

Season 15 retunes the reward side of terrorized content:

The direction is clear: Blizzard is pushing sunder-charm acquisition toward Herald encounters and away from passive magic-find farming. Our sunder charms guide and Terror Zone tracker & schedule page go deeper on farming the new rules.

Bug fixes worth knowing about

Thirteen fixes ship with the patch. The ones that affect gameplay:

The Sigil: Death and Miasma Chain fixes matter if you play the fire side of the Warlock's Arts of Chaos tree — both skills now behave the way their tooltips always claimed. Our Warlock skill tree page covers where they sit.

What is not in Patch 3.3

There are no class balance changes, no new runewords and no new content systems in this patch — Blizzard bundled everything into the season announcement rather than a separate notes article, and the official forums have plenty of players calling the patch thin. Set your expectations accordingly: Season 15's draw is the fresh ladder economy, not a new meta. Your Season 14 builds carry over unchanged, so the prep advice in our start date guide stands.
