The Wrath of Pyrakmon

One-Shot · 6 Players · Level 8 · Greek Mythology · ~3.5 hrs / 3 Encounters

SESSION SUMMARY

Style: Mythic Sea Voyage / Dungeon Assault
Setting: Isle of Kyklos — open Aegean trireme deck, ruined coastal temple, Cyclops sea cave
Win Condition: Defeat Pyrakmon, rescue Elara's crew, recover the Naxian Seal
Players: 6 × Level 8 · ~3.5 hours · Quest Object: Wineskin of Maron (payoff Enc. 3)

A Naxian merchant hires the party to reclaim her crew and the Naxian Seal from the Elder Cyclops Pyrakmon. Survive a harpy ambush at sea, navigate a Medusa's shattered temple, then confront Pyrakmon in his cave — Elara's divine wine is their best edge: "No giant can resist it."

"Sailors of fortune — my name is Elara of Naxos. The creature Pyrakmon has taken my crew and my livelihood from the waters between here and his wretched island. I offer eight hundred gold pieces to any soul brave enough to see them returned. Come to the Anchored Krater before the tide turns. I have a gift that may prove useful — something the giant cannot resist." — Note by harbour boy, blue wax seal · Elara of Naxos

Major Beats

Hook — The Anchored Krater: Elara briefs the party, hands over the Wineskin of Maron, and explains Pyrakmon cannot resist divine wine.
Encounter 1 — Storm of Feathers: Harpies + Matriarch attack the trireme. Sail survival determines rest before landing.
Encounter 2 — The Shattered Temple: Kithara the Medusa guards the cave path — fight, sneak, or negotiate for fire-vulnerability intel.
Encounter 3 — The Eye of Pyrakmon: Storm the cave; use the wineskin; target the eye; free the bone-cage crew; recover the Seal.
Resolution: Crew freed, Seal recovered. Elara pays; if pressed, reveals the Seal's true power as a campaign hook.

A desperate Naxian merchant hires the party to brave the Isle of Kyklos, where the Elder Cyclops Pyrakmon has seized her crew and her most prized possession — the Naxian Seal, a trade charter with hidden divine power. The heroes must survive a harpy ambush at sea, navigate the petrifying domain of a vengeful Medusa, and finally confront Pyrakmon himself in his reeking cave. Elara has pressed a flask of supernaturally potent wine into their hands and assured them: "No giant can resist it." Shrewd Aegean merchant. Provides the party with the Wineskin of Maron and a briefing: Pyrakmon is a glutton for fine wine and will accept it as a peace-offering before turning violent. Secret: The Naxian Seal is a Binding of Poseidon — the holder can command sea-spirits to fill or deny sails within ten miles. She hasn't told the party.

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 — Storm of Feathers

Medium · ~20–25 min · ~4–5 rounds · 5× Harpy + 1× Matriarch · XP adj. ~3,400 | Terrain: Trireme Deck, 60×20 ft

Storm-cover ambush at sea. Two harpies bank for sails; Matriarch dives highest-AC PC. Charmed oarsmen are the clock. Win: kill/drive off all harpies before sails destroyed and too many crew overboard.

Sails (2): AC 10, 20 HP each. Both intact = Long Rest before Enc. 2; one down = Short Rest; both down = no rest + 1 Exhaustion each PC. 3 crew overboard = treat as both sails down.
Terrain: Rigging difficult (DC 12 Ath/Acro climb 15 ft w/o Dash); Crow's Nest 25 ft (DC 13 Ath); Mast = ¾ cover; oar banks = half cover (dive attacks disadv.); wind: PC shots NW disadv.; harpy shots with wind adv.
Overboard: Rail + fail DC 12 DEX when pushed/charm-walked → sea; swim 15 ft/rd; DC 14 Ath/rd or +1 Exhaustion.
Init: 5 harpies as group; Matriarch separate. Sail Targeting: 2 designated harpies claw sail as action (no attack vs Sail AC if uncontested). PC Reaction interpose → take claw hit instead.
Luring Song — Crew: 8 crew WIS +0; DC 11 WIS start of turn or walk toward singer. Matriarch Song DC 14.
Matriarch AI: R1 Dive Bomb (40 ft descend); R2 Talon Rake grapple + lift 15 ft. Flee: no Matriarch + 3+ harpies dead → DC 11 WIS morale next rd.
Skill checks: DC 13 Ath (BA, adjacent) grab charm-walker; DC 14 Animal Handling calm charm; DC 14 Performance counter-sing 1 crew (Matriarch targets counter-singer next); DC 15 Perception spot Matriarch pre-R1 (loses Dive Bomb BA).
Harder: 7 + 2 Matriarchs; 1 hidden crow's nest Surprise; sails 15 HP. Easier: 3 Harpies, no Matriarch; Song DC 9; sails 30 HP; 5 crew.

Failure: Both sails destroyed → row exhausted, no rest, 1 Exhaustion into Enc. 2. 4+ crew lost → Kairos unavailable in Enc. 3.

Resolution: Both sails intact → Long Rest. One sail → Short Rest. Matriarch corpse DC 12 Investigation → silver armband (eye + ΠΥΡ) — Pyrakmon sentinel hint. Grappled PC falls ≤15 ft (1d6) if Matriarch dies mid-lift.

ENCOUNTER 2 — The Shattered Temple

Hard · ~30–35 min · ~5–6 rounds · 1× Kithara + 4× Skeleton Archer · or bypass | Terrain: Ruined Coastal Temple, 80×60 ft

Medusa Kithara (cast off by Pyrakmon) animates petrified victims. Not mindlessly hostile — hates Pyrakmon. Win: defeat or bypass; clear path to sea cave. Bonus: stand-down → fire weakness + crew alive intel.

Terrain: 8 columns (¾ cover; LoS break = Gaze off); 4 deep-shadow 10×10 zones (lightly obscured; DC 16 Perception locate Kithara — she starts in shadow); Altar centre (DC 14 Religion → Adv.

Bronze Mirror: Action angle shield → Kithara DC 15 CON or Restrained until end of her next turn; immune after first successful save. Full Action — hand to support PC.
Negotiate: Call "We are enemies of Pyrakmon!" (Action) → she skips that PC this rd (skeletons still act). DC 15 Persuasion → skeletons off 1 rd, listens. DC 17 Persuasion + proof (wineskin or Matriarch armband) → full stand-down, free shield, full intel (eye +2d6 fire; right-socket blind spot; crew in bone cage). Won't join combat; leaves island if given proof of his death.
Skeletons: Awaken Dead BA R1. Crumble if she dies. Never animate if negotiated before R1. Prioritise PCs not averting eyes.
Stealth bypass: DC 14 group Stealth. Success: no combat, no intel. Fail: Surprise + all PCs DC 14 CON or start Restrained.
Harder: 6 Skeletons; regen 10 HP/turn while any stand; Gaze DC 15. Easier: 80 HP, Gaze DC 12; 2 Skeletons; Persuasion DC 13.

Failure: Stealth fail → Surprise + possible Restrained openers. Petrified PCs freed later are Stunned until end of next turn.

Terrain: Fire pit 15×15: 3d6 fire (DC 14 DEX half); shove into pit free with Greatclub if within 10 ft. Bone cage N: freed sailor while he's alive = 1-in-4 chance next Rock (DC 15 DEX or 4d10+7). Chains: DC 18 Ath break early; he releases both BA R1. Rock piles unlimited ammo. Stalactites above pit: DC 16 attack/STR → 20-ft zone 2d10 (DC 16 DEX half) + extinguish fire (dim light).

KEY ITEMS

◈ Wineskin of Maron

Wondrous Item (Uncommon) · Session McGuffin · 3 Uses · Given by Elara at start

Appearance: Hammered gold flask, grape-vine relief · 2 lb. Wine of Maron, priest of Apollo — supernaturally potent; Giants have Disadvantage on the CON save.

Pre-Combat Offer (best): Offer before initiative — Pyrakmon accepts greedily. Distracted 1 full round → free surprise round of actions.

Combat (Action): Adjacent: DC 15 Athletics or Sleight of Hand to deliver 1 measure. Target must be willing or Grappled. Pyrakmon: Disadv. on DC 17 CON. Fail: Poisoned + Incapacitated until end of his next turn. Success: Poisoned only (Disadv. attacks/checks).

All 3 uses: Automatic fail. Incapacitated 2 full rounds — prime window for eye called shot (AC 20, 15+ dmg → Blinded permanently).

DM note: Only Maron's vineyard can refill — potential campaign hook.

Naxian Seal

Quest Object · Recover from Pyrakmon's shiny pile (N wall) · DC 14 Investigation

Appears as: Trade charter / merchant seal of Naxos.
True nature (Elara's secret): Binding of Poseidon — holder can command minor sea-spirits to fill or deny sails within 10 miles.
Reward: 800 gp on delivery; +200 gp if all 6 crew alive. If party confronts Elara about the Binding: she claims it by Naxian law; offers one extra warehouse magic item for silence. Campaign hook if revealed.

NPC QUICK REFERENCE

Elara of Naxos — Quest Giver

Medium Humanoid (Human), NG · Non-Combatant · Merchant of Naxos

Appearance: Mid-forties, salt-bleached hair, ink-stained fingers; sea air + expensive perfume. Rarely raises voice; never bluffs when she can negotiate. Carries small bronze knife; will not fight. Languages: Common, Elvish.
Motivation: Rescue her 6-person crew; recover the Naxian Seal; return home. Pays 800 gp + 200 bonus if all six survive.
Secret: Seal is a Binding of Poseidon (sail fill/deny within 10 mi). Hasn't told the party — fears they keep it.
Roleplay: Briefs at Anchored Krater; hands Wineskin; insists Pyrakmon is a glutton for fine wine. If confronted about Seal: "Mine by Naxian law and Poseidon's blessing" — offers one extra magic item for silence.
Stats: Non-combatant — no combat block.

Captain Kairos — Trireme Captain (Ally)

Weathered sailor · Loyal to Elara's coin · Commands 8 oarsmen

Motivation: Get the ship and crew home; follow Elara's contract.
Role in Enc. 1: Survives unless DM rules otherwise. Crew charm-walks are his crisis. Beaches at island cove and waits.
Enc. 3 assist: If signalled and ≤3 crew lost Enc. 1, arrives end of Round 6 with 4 oarsmen to carry out survivors. If 4+ crew lost overboard, unavailable (managing reduced crew).
Roleplay: Practical, curt; improvises if sails/crew fail but party drifts (treat as both-sails-down rest).
Stats: Ally NPC — no combat block needed; focus on timing / availability.

Kithara — Medusa of the Shattered Temple

Potential Ally · Enc. 2 guardian · Full combat stats on page 3

Motivation: Survive in bitter solitude; hate Pyrakmon with cold ferocity. Enslaved by him years ago, discarded when she displeased him. Animates petrified prior visitors as Skeleton Archers.
Secret / Intel if stand-down: (1) Eye vulnerable — fire attacks deal +2d6 to the eye; (2) slight blind spot to the right of the socket (old scarring); (3) sailors alive in bone-and-chain cage at cave rear.
Roleplay: Pause if PC calls "We are enemies of Pyrakmon!" DC 15 Persuasion = listen 1 rd; DC 17 + proof (wineskin / Matriarch armband) = full stand-down, free Bronze Shield, full intel. Award full combat XP. Won't fight alongside party; promises to leave island if given proof of his death. Recurring NPC potential.
Stats: AC 15, HP 127, Gaze DC 14 — see creature card. Dying merciful kill may whisper eye intel.

Session Aftermath & Hooks

Full victory: All crew alive + Seal → 1,000 gp total; Elara may reveal Binding if pressed.
Partial: Pyrakmon down, crew losses → 800 gp, no bonus; Seal still recoverable.
Hoard: 1,200 gp coin/jewellery; Protection from Evil and Good scroll; Stone Shape scroll; Trident of Fish Command.
Hooks: Wineskin refill only at Maron's vineyard; Seal Binding as political/naval power; Kithara as recurring ally if Pyrakmon dies; Matriarch armband proves Cyclops uses harpy sentinels island-wide.
