D2R Reign of the Warlock Guide | New Class, Build & Endgame Tips

When the "Diablo 30th Anniversary" livestream revealed that shadowy figure draped in forbidden runes, commanding the very demons of the abyss, the collective heartbeat of the community skipped a beat. It felt like the year 2001 all over again.

Diablo II: Resurrected (D2R) has always been celebrated for its "original flavor." But today, 25 years after the Lord of Destruction expansion, Blizzard has taken a historic leap with the all-new DLC: Reign of the Warlock. This isn't just a new character class; it's a profound evolution of the game's core mechanics.

From the new Warlock class to the brutal Colossal Ancients endgame boss, here is everything you need to know to dominate the ladder.

The New Challenger: The Warlock Class

For the first time since 2001's Lord of Destruction, a new hero joins the roster. The Warlock is a master of forbidden arts, utilizing demon summoning and elemental corruption.

Three Skill Paths: Demon: Bind hellspawn to your will as loyal pets.

Eldritch: Imbue weapons with mental magics for a hybrid melee/caster playstyle.

Chaos: Unleash raw elemental fire and shadow from a distance.

Strategy Tip: The Warlock relies heavily on +Skill items and Faster Cast Rate (FCR). Early-game gear like the "Leaf" Runeword is a game-changer for Chaos builds.

Game-Changing Quality of Life (QoL) Updates

The "Infernal Edition" finally addresses decades of player feedback with modern features:

In-game Loot Filter: Say goodbye to screen clutter. Customize what you see, from High Runes to Elite Bases.

Stackable Items: Gems, Runes, and crafting materials now stack, finally freeing up your precious stash space.

The Chronicle System: An account-wide collection tracker that rewards you for finding every Unique and Set item in the game.

Advanced Endgame: Terror Zones & Colossal Ancients

The endgame is no longer just "Baal Runs."

Terrorized Acts: You can now use consumables to manually trigger Terror Zones in specific Acts, scaling difficulty and loot to the maximum.

Colossal Ancients: By defeating Terrorized Act Bosses, you can collect five mystical statues. Combine them in the Horadric Cube to face the Colossal Ancients—the most difficult challenge in D2R history.

Pro-Tips for Fast Leveling & Wealth Building

If you are starting fresh or returning for the Warlock, keep these Runewords in mind:

Stealth(Tal + Eth): Essential early-game armor for movement and casting speed.

Spirit(Tal + Thul + Ort + Amn): The GOAT caster sword/shield. High CP value for the Warlock.

Insight(Ral + Tir + Tal + Sol): Give this to your Act 2 Mercenary for infinite Mana (Meditation Aura).

Lore(Ort + Sol): A cheap +1 All Skills helmet to boost your summoning power.

Must-Complete Quest Checklist

Don't skip these essential side quests that provide permanent character boosts:

Act 1: Den of Evil – +1 Skill Point & Stat/Skill Reset.

Act 2: Radament's Lair – +1 Skill Point.

Act 3: Lam Esen's Tome – +5 Stat Points.

Act 4: Fallen Angel – +2 Skill Points (The most important quest!).
