Grief Demon

What — Faceless, expressionless humanoid demon that feeds on sadness; likely tied to the Demonic Chantry and may have crawled up from the underworld beneath The Clapton's Hammer in Gwyndinas.

Threat — Deadly in melee, otherwise moderate: it reflects every hit back at the attacker, so brute force is self-harm — the killing blow knocked Draak unconscious from his own reflected damage. Cheap to drop once you bring silver.

Observed abilities (Session 13)

• Damage reflection — every blow struck against it deals equal damage to the attacker (5/5, 17/17, 23/23 traded in play). Confirmed not weapon damage, so PC physical resistances (e.g. barbarian rage) did not reduce the reflected hit.
• Soul-bind / control — bound Ashlyn Blackwood ("eyes turn black"), puppeting her to attack Llashanna; the GM noted her soul was "a little bit stronger" suggesting an opposed/save contest, but no DC was stated.
• Implant false memories — fed grief by forcing each victim to relive a tailored loss (Silithane Stormrivven, Draak, Fenric Vale, Magra Greysong). Memories persisted even after its death. No save number given.
• Permanent darkness — its lair sat behind a wall of magical darkness; pervasive soul-depressing aura over the whole tavern. (Gap: not clearly a discrete combat action.)
• Commanded animated skeletons in the cavern (these later turned to fight with the party once it fell).

Resistances / immunities / weaknesses

• Weak to silver — takes double damage. This was the key to the kill (16 → 32) and the only thing that visibly hurt it ("nothing seems to come out" from other weapons).
• The reflection effect itself appears to bypass damage-type resistances on the attacker.

Tactics & behavior — Lurks, doesn't maneuver — low AC ("a 10 will just hit," unarmored, not trying to dodge). Wins attrition by mind-controlling allies and punishing every attack. When the silver sword was drawn it locked solely onto the wielder (Draak) and threw up its hands in panic ("Tom Riddle diary" weakening) — i.e. it visibly fears silver and the bearer of it. Did not flee or surrender; fought to dissolution.

Disposition to the party — Hostile. Drained and tormented the party (and the tavern's patrons) with grief; mind-controlled Ashlyn Blackwood against her own group.

Status — Dead. Slain by Draak with the silver sword in Session 13; its body sizzled to dust and demonic ectoplasm. (Gap: exact HP/AC never stated — it was "bloodied"/halved after a 17-damage crit and dropped at 32 silver damage. Note the tunnel below its lair reportedly runs toward the underworld — possible source of more such demons.)

SUMMARY: Sadness-feeding demon that reflects all damage; dead, slain by silver Session 13.
