The Weeping Maw

3.5-Hour Oneshot · 6 Players · Level 8 · Wilderness Crawl → Boss Fight

SESSION SUMMARY

Style: Wilderness Crawl / NPC Recruitment / Boss Fight
Setting: Frontier wilderness — dense forest → boggy marsh → rocky cave mouth; overcast, humid, rot & sulfur; late morning → dusk
Win Condition: Slay the Marsh Hydra (cauterize stumps with fire to prevent regrowth)
Players: 6 × Level 8 · ~3.5 hours

Village elder Aldric Vane hires the party to stop disappearances along the forest road. A Marsh Hydra has claimed a cave deep in the wild. Aldric gives the Scroll of Splashfire Blessing (maguffin; 1 PC may keep it) and a sealed note — show the note to Lysander for fire lore + 2× Fire Flask backup.

"Fire does not merely wound — it silences. What steel severs, flame must seal. Take the Splashfire Blessing — coat a bow before the cave. Ask the blind priest at the old shrine; he will know." — Aldric Vane

Major Beats

Aldric delivers the quest, Scroll of Splashfire Blessing, sealed note, and warning: "seek allies before they reach the cave."
Enc. 1 — Thornwood Ambush: Free Bryn & Cael from gnolls; recruit them for Enc. 3.
Party reaches overgrown frontier-shrine ruins under a grey sky; undead patrol the courtyard.
Enc. 2 — Old Frontier Shrine: Clear skeletal guardians; scavenge items; recruit Lysander (show note for fire lore, Splashfire coaching, + 2× Fire Flask).
Dusk at the cave mouth — bones, shuddering ground; the Hydra emerges.
Enc. 3 — The Bilewyrm's Maw: Activate Splashfire on a ranged weapon; sever heads; burn stumps same turn. Victory — one PC keeps the scroll.

Difficulty Scaling

Encounter	Easy	Medium (baseline)	Hard
1 — Ambush	4 Hunters; Pack Lord no Frenzied	6 Hunters + Pack Lord	+1 Hunter; Incite Rampage immediately
2 — Shrine	6 Hoplites, 1 Minotaur (HP 45); no Reformation; no wave 2	8 Hoplites, 2 Minotaurs	10 Hoplites (+2 HP); +1 Minotaur; Wave 2 on rd 3
3 — Maw	4 heads; no poison condition; no Bog Lurker DT	5 heads, max 7	Max 9 heads; Mud Thrash 20 ft; poison on all bites

Maguffin: Scroll of Splashfire Blessing (from Aldric). BA 1/LR → coat a ranged weapon 10 min. Hit: target + creatures within 5 ft take 2d4 fire. Miss: intended target takes 1d4 fire. Counts for Head Regrowth. Quest reward: 1 PC keeps it.

Note payoff: Show Aldric's note to Lysander (Enc. 2) → full fire/regrowth explanation, Splashfire coaching, + 2× Fire Flask. Without Lysander: scroll still works from Aldric's brief; discover why fire matters with DC 15 Nature/Arcana (1/turn) mid-fight.

NPC recruitment impact (Enc. 3): Splashfire on a PC/Hunter bow usually covers fire even without Lysander. Unused scroll + 0 NPCs = hard (7-head risk). Lysander still best for healing/Bless + coaching.

DM Tips

As Written ★ — 6 Players, Average Level 8: Baseline for this guide. Numbers, DCs, and win tracks assume six PCs at average level 8.
Easier: APL 4–6: reduce minion counts ~30%; DCs −2; boss loses one recharge or legendary option.
Harder: APL 10–12: boss HP +25–35%; +1 legendary action; add a lieutenant or extra wave.

ENCOUNTER 1 — The Thornwood Ambush

Moderate · ~45 min · ~4–5 turns · 3,000 XP | Terrain: Forest Trail 80×60 ft

6× Gnoll Hunter + 1× Pack Lord mid-ambush; Bryn & Cael bound by overturned cart. Win: defeat gnolls, free hunters, recruit for Enc. 3.

Terrain: 3× fallen logs (½ cover); 2× boulders (¾ cover); overturned cart (½ cover, blocks move); E undergrowth strip 10 ft DT; dappled light (no darkness penalty).
Free hunters: DC 12 Athletics or Dexterity to cut/untie, or 1 attack on ropes. Freed hunter joins next turn on own init. 2 Hunters guard cart — attack PCs adjacent to bound hunters.
Recruit (after combat): DC 12 Persuasion (duty/village/honor); DC 14 Intimidation (comply but −1 attacks Enc. 3); DC 11 Insight first → lost companion to the creature — address it = auto-Persuasion. No check if same guild/region/knows them.
Pack Lord behind boulder directing; flees ≤15 HP if pack mostly dead. Rampage: gnoll that drops a PC can BA Bite again — watch unconscious PCs.

Failure: Hunters not recruited → Enc. 3 has no ranged DPS (~10–14 dmg/rd) and no Hunter's Mark.

Resolution: 2× Trail Hunter join Enc. 3 — boulder perch, longbow, init 12. Bryn uses Hunter's Mark on Hydra turn 1.

ENCOUNTER 2 — Ruins of the Old Frontier Shrine

Moderate · ~50 min · ~6–8 turns · 2,350 XP | Terrain: Ruined Shrine & Courtyard 120×90 ft

Baseline 8× Skeletal Hoplite + 2× Skeletal Minotaur (overview lists 10/3 for denser load). Pyrrha & Lysander shelter at outer wall. Win: clear undead; scavenge; recruit Lysander.

Terrain: broken columns (½ cover); 3× fallen stonework DT; E vines DC 13 Athletics climb/swing; collapsed altar inner courtyard; cave steps beyond inner temple.
Patrol: 5 hoplites outer courtyard; 5 + 2 minotaurs near cave steps. DC 12 Perception → notice pattern; ambush plan = adv. on initiative.
Shield Wall: hoplites within 5 ft get +2 AC. Reformation: 0 HP → prone, rises next init with 5 HP unless radiant/fire/bludgeoning while prone. Learn via DC 15 History/Religion.
Minotaur Charge: DC 14 STR or prone + pushed 10 ft. Wave 2 (rd 4 / Hard rd 3): +4 Hoplites from cave mouth.
Pyrrha: DC 14 Persuasion (or rescue) → Polished Bronze Mirror + Stonechill Water locations; patrol intel = adv. init.
Lysander + note: DC 13 Insight → fire lore + Splashfire coaching; aid DC 8; gives 2× Fire Flask. Without note: DC 13 Insight → Blindfolds if entering the cave.
Scavenge: Mirror; Stonechill ×2; Blindfold of Apollo ×3; Oil of Stonecleansing ×1; Fire Flask ×2 (note → Lysander). Maguffin scroll is already from Aldric.

Failure: No Lysander → no coaching/flasks; party may forget to activate Splashfire or not know why fire matters (DC 15 Nature/Arcana mid-fight).

Resolution: Scavenge items for Enc. 3. Lysander joins Enc. 3 on init 10 (Sacred Flame, Cure Wounds, Bless, Splashfire callouts) if recruited.

ENCOUNTER 3 — The Bilewyrm's Maw (Boss)

Moderate · ~70 min · ~6–8 turns · 3,900 XP | Terrain: Cave Entrance 120×90 ft

1× Marsh Hydra (5 heads, HP 155) at cave mouth — not surprised (Wakeful). Optional allies: hunters (init 12), Lysander (init 10). Win: reduce Hydra to 0 HP; fire on final sever turn = permanent kill.

Terrain: flanking cliff routes; cave mouth 30×25 ft (60 ft dark — Hydra won't retreat in); 4× boulders ¾ cover (hunter perches); 2× bog pools 20×20 DT; 2× bone piles 10×10 DT; N/S cliffs 30 ft, climb DC 14 Athletics.
Bog Lurker: 30 ft radius always DT; DC 13 Dex or −10 ft speed.
Sever head: ≥25 damage in one turn from one or more melee attacks. End of Hydra turn: +2 heads per severed since last turn (max 7) unless any fire damage this turn.
Fire sources: Scroll of Splashfire Blessing (primary — 2d4 on hit / 1d4 on miss for 10 min); Lysander Sacred Flame 1d8/turn; Fire Flask ×2 (BA 10 ft / Action 20 ft). Unused scroll + no other fire → caps at 7 heads. Learn weakness: DC 15 Nature/Arcana once/turn.
Reactive Heads: +1 reaction/head beyond first (OA only), max +4. Reach 10 ft. Mud Thrash (recharge 5–6): 10 ft, DC 15 Str or prone + restrained (DC 13 Athletics escape).
Allies: Hunters longbow +5 from boulders (~10–14 dmg/rd combined); Bryn Hunter's Mark +1d6 (1/enc). Lysander Sacred Flame + Bless + emergency Cure Wounds.

Failure / no fire: 7-head hydra for multiple turns — activate Splashfire early; flasks/Lysander as backup.

Reward: One PC keeps the Scroll of Splashfire Blessing after victory.

Victory: HP 0 ends fight. Fire on final head-sever turn cauterizes stump permanently. Aldric pays bounty on return; recruited NPCs stay as frontier contacts.

Handout · Given at session start

Text: "Fire does not merely wound — it silences. What steel severs, flame must seal. Take the Splashfire Blessing — coat a bow before the cave. Ask the blind priest at the old shrine; he will know."

Payoff (Enc. 2): Show to Lysander → he recognizes Aldric's hand, explains Head Regrowth, coaches Splashfire activation, gives 2× Fire Flask; recruitment aid DC 8.

Without Lysander: scroll still usable; DC 15 Nature/Arcana mid-fight (1/turn) to learn why fire matters.

Scroll of Splashfire Blessing

Wondrous Item (maguffin) · From Aldric · Quest reward (1 PC keeps)

Soot-edged scroll. Activate (BA, 1/LR): coat one ranged weapon for 10 minutes.

Hit: Target takes extra 2d4 fire; each other creature within 5 ft. also takes 2d4 fire.
Miss: Intended target still takes 1d4 fire.
Hydra: Any Splashfire fire seals Head Regrowth that turn. Ideal on a PC archer or Trail Hunter bow.
Reward: After victory, one character may keep the scroll.

Fire Flask ×2

Improvised Weapon · From Lysander (note shown) · Backup

Clay flask of marsh-pitch fat + striker-wick. Shatters; sticky flame.

Action: Throw ≤20 ft (+PB Dex). Hit: 2d6 fire.
Bonus Action: Throw ≤10 ft (+PB Dex). Hit: 2d6 fire; miss: 1d6 splash to target.
Special: Any hit = fire damage to Hydra this turn → no head regrowth at end of Hydra's turn.

Gaze deflection via reflection. Bonus action to angle at reflective surfaces (DC 14 Sleight of Hand). Location unlocked via Pyrrha (DC 14 Persuasion / rescue).

Throw range 20 ft.: target speed halved; disadvantage on next save vs. breath effects. Pyrrha reveals location (DC 14 Persuasion).

Blindfold of Apollo ×3

From Lysander · Freely given if party enters cave

While worn: blindsight 15 ft.; immune to gaze-based effects. Lysander carries them; offers freely if told the party intends to enter (or with note path).
