Wreathed in Dark: The Warlock's Lore

[Link]

Warlocks are dark, relentless casters who bend demons and the powers of Hell to their will. Hell itself is the source of their power, conjured through ritual, alchemy, and spellcraft. The Warlock is not a servant of Hell; they are its bane, using its unholy fruits against itself.

Not everyone has the ability to become a Warlock. It takes natural-born insight, exceptional willpower, and rigorous training to resist the temptation of corruption. Even the best can fail. They roam the world as ragged outcasts, scavenging their forebears' knowledge-some seeking mastery over their inner demons, others hunting demons where they rise.

The Vizjerei: Origins of the Warlock

[Link]

Birthed from forbidden knowledge that ignited The Sin War, the original demon summoners were Vizjerei who sought this power in secret. The discovery of this blasphemous craft tore the mage clans into civil war. In the aftermath, demonology was outlawed once again, and its remaining practitioners-branded "Warlocks"-were hunted across Sanctuary.

Nearly 15 centuries later, underground enclaves keep this knowledge alive, believing it essential to humanity's survival. Few Warlocks are raised in the practice; many are simply born with demonic insight, a cursed gift that often leads to rejection by society.

[Link]

The more fortunate ones find old, accursed seals, driven by voices they appear to hear from within. These seals are tenets of their study, guiding their practice. The knowledge within is often incomplete and varies by discipline.

These are sources of inspiration for how the Warlock exudes their power, influencing how they understand the world and shape it to their will. These are not their skills, but a foundation of their ceaselessness.

• Force of Will - Above all, warlocks must strengthen their will against opposition, striving to purge fear, doubt, and weakness.
• Demonology - The history, taxonomy, physiology, psychology, summoning, and subjugation of demons. From the lowest maggot to the Prime Evils.
• Hellfire - Theory, conjuration, and application of Hell's destructive elements.
• Shadow - Tools of deception, inception, and manipulation, useful both in combat and subterfuge.
• Martial Weaponry - Symbolic and literal extensions of the warlock's will.

[Link]

Once a Warlock has begun their practice of tearing open the veil between worlds, they cannot stop. Their hunger for power and purpose is insatiable, stronger than any pain they endure.

Now, after centuries of working in secret, many warlocks believe Mephisto's return signals their ultimate test is at hand. They rise from the shadows to meet this challenge.

Annihilate your Foes with Diabolical Skills

[Link]

The Warlock is a visceral caster that conjures Hell and exploits demons as tools, quickly summoning them to unleash demonic onslaught against their foes. Summoning demons is a challenge for Warlock-it is a constant, painful struggle to resist corruption. The Warlock walks a razor's edge, pushing the limits of their control while never allowing it to break.

Class Resource: Wrath & Dominance

Skills consume Wrath, while summoning Demons and using their abilities cost Dominance. Mastering both of these resources is necessary to become the pinnacle of hell-summoning prowess.

If the pen is truly mightier than the sword, the Warlock's tome may perhaps be best evidence of that epithet.

New Keywords:

• Hex
  • Increases Abyss skill damage taken against enemies, based on their missing Life. Stacks up to 3 times.
• Eviscerate
  • Eviscerated enemies instantly lose a portion of their Bleeding Life and then Bleed for additional damage.
• Shadowform
  • Shadowform grants Unhindered and any movement grants Stealth but consumes stacks.
• Demonform
  • Increases your Maximum Life. While active, kills increase the damage of Demonology Skills.
• Volatility
  • Randomly Empowers Hellfire Skills when you attack with them. Empowered skills deal increased damage on their next cast.

Harness Soul Shards: Warlock Archetpyes

[Link]

Those who take up the Warlock's burden fuse soul shards into their bodies, manifesting power through one of several forbidden archetypes:

• Legions summon relentless fodder to overwhelm their prey
• Vanguards become monstrous front-line terrors
• Masterminds seize the battlefield through oppressive shadowcraft
• Ritualists weave doom through blood-etched rites

Harness Soul Shard Fragments

After reaching Level 30, the Warlock's Class Mechanic unlocks. Select one of four Soul Shards to infuse yourself with that power, imbuing your summoned demon with precise fervor.

Choose wisely; for the Soul Shard defines which demon is linked to you and establishes the core of what your Warlock focusses on.

Soul Shards are made up of two components:

• Primary Shards:
  • Grant a transformative playstyle passive which alters your core gameplay loop. Summoning demons, controlling them, how effects are chained together.
  • Binds a specific demon to you.

Do not mistake your summoned demon as a companion. To do so would be a slander to your craft and the indomitable will it takes to force a servant of hell to turn against its master.
