With the release of Arcane Season 2 on Netflix, we are once again thrown into the streets of Piltover and Zaun as factions vie for power in the wake of a devastating attack. The conflict and intrigue in these cities is captivating and, crucially, provides wonderful inspiration for your own TTRPG designs.

Last time, we looked at how to steal ideas from the gleaming upper city of Piltover. The second act of this season brings bombshell revelations regarding the fates of several major characters from the first season. A new monster terrorizes the lanes of Zaun, drawn by the scent of blood . . . SPOILERS AHEAD!

Warwick’s Lair

The gray alleys of Zaun are Warwick’s hunting ground, where he spends his time preying on those who terrorize the city’s depths.

LAIR ACTIONS

On initiative count 20 (losing initiative ties), Warwick can take a lair action to cause one of the following effects; Warwick can’t use the same effect two rounds in a row:

• Collateral Damage. Warwick destroys a nearby structure, causing it to collapse. Each creature in a 30-foot-long, 10-foot-wide line starting at a point Warwick can see must succeed on a DC 15 DEX save or take 7 (2d6) bludgeoning damage. The area then becomes difficult terrain.

• Gray Burst. Warwick tears into a nearby pipe, causing the factory smog known as the gray to burst forth. A 20-foot-radius sphere of haze appears centered on Warwick. The sphere spreads around corners, and its area is heavily obscured. A creature that starts its turn in the sphere must succeed on a DC 15 CON save or take 7 (2d6) poison damage and be poisoned until the start of its next turn. The sphere lasts for 1 minute, until Warwick uses this lair action again, or Warwick dies.

• Sow Dread. A wave of menace washes out from Warwick. Each creature within 60 feet of him that that can see or hear him must succeed on a DC 15 WIS save or suffer disadvantage on their next attack roll or ability check before the end of their next turn.

REGIONAL EFFECTS

The region containing Warwick’s lair is plagued by fear, which creates one or more of the following effects:

• Blood Trails. Random blood trails appear within 10 miles of Warwick’s lair. These trails often lead creatures into dark and abandoned places. Creatures that follow a trail hear a dull mechanical heart beat that gets faster as they near its end.

• Mysterious Disappearances. Every month, 1d4 criminals go missing within 10 miles of Warwick’s lair.

• Paranoia. Within 10 miles of Warwick’s lair, creatures always feel as though they are being watched by some unseen figure.

If Warwick dies, these effects end immediately.
