"Not the hero's name — the sand's. Strike the hide, stake the charge, leave the legend empty."— Carved on the Olive-Resin Club's twelfth notch

Key NPCs

  • Archon Melanthios — Host; forbids naming Heracles in the arena.
  • Thaleia of the Bit — Stablewright; pens, nets, and horse-sense.

Major Beats

  • Mist → stadium; club gifted; six labor-gates named.
  • Gate I: Lion (hide) → Hydra (heads + fire cauterize; Head Tracker).
  • Gate II: Mares (recruit Thaleia) → Stymphalian flock (thunder / nets).
  • Gate III: Erymanthian Boar (capture preferred) → Cretan Bull (Hard; stake the club).
  • Mortal olive crown — no demigod steals the ending.

Encounter 1 — Gate I: Lion & Hydra

Medium–Hard · ~50–55 min · Waves 1–2 · Labors I & II

Overview

Two waves, 2–3 minute gate-reset (no short rest). Nemean Lion first, then the Lernaean Hydra — same multi-head puzzle the library uses elsewhere, compressed for the sand.

🗺 Terrain

Stadium floor · 80×80 ft sand · 10-ft wall · four gates · two sand-pit traps (DC 14 Dex or prone) · braziers at each gate (lit; fire for cauterize) · mural ring of the Twelve Labors.

Wave A — Nemean Lion

  • Win: 0 HP, pin (3× Athletics DC 16 after bloodied), or drive through North gate.
  • Hide ignores mundane non-bludgeoning; Olive-Resin Club ignores once/encounter.
  • Chant Clock: hush demigod-name shouts (Intimidation/Persuasion DC 14).

Wave B — Lernaean Hydra

  • Start 5 heads. Sever on 25+ damage hit (or called shot). Multiattack = number of heads.
  • Cauterize stump with fire/acid same round (torch from brazier, spell, or club + flame) or it regrows two heads at end of hydra's turn (max 8).
  • Win at 0 heads or 0 HP after final head. Handlers flood the sand if the fight exceeds ~8 rounds.

Hydra Head Tracker

Click a head to sever it (after dealing a head-severing hit). Use + Regrow Head if the stump was not cauterized with fire or acid.

Active heads: 5 · Max: 8 · Reactions: 5

Nemean Lion (Arena Echo)

20 (+5)STR
15 (+2)DEX
18 (+4)CON
4 (−3)INT
14 (+2)WIS
10 (+0)CHA

Skills: Perception +6, Stealth +6

Hide That Will Not Cut. Immune to damage from nonmagical attacks that aren't bludgeoning. Magical piercing/slashing deals half. Bludgeoning, force, and the Olive-Resin Club ignore this trait.

Pounce. If the lion moves at least 20 ft. straight toward a creature and hits with a claw, the target must succeed on a DC 16 Strength save or be knocked prone. Bite as a bonus action.

Arena Echo. Slayable labor-echo. Same iconic threat as other lion hunts in the library — Heracles is not present.

Attack. Bite +9 to hit, 16 (2d10 + 5) piercing plus 7 (2d6) thunderous roar damage, or Claw +9 to hit, 14 (2d8 + 5) slashing. Multiattack: two claws or one bite.

Roar of the First Labor (Recharge 5–6). Each creature of the lion's choice within 30 ft. that can hear it must succeed on a DC 15 Wisdom save or be frightened until end of its next turn.

🐍

Lernaean Hydra (Arena Echo)

Huge Monstrosity · CR 8 · Wave 2 · Labor II · Library centerpiece

20 (+5)STR
12 (+1)DEX
20 (+5)CON
2 (−4)INT
10 (+0)WIS
7 (−2)CHA

Starts with 5 heads. Use the Head Tracker below.

Multiple Heads. While it has more than one head, advantage on saves vs. blinded, deafened, stunned, and charmed. Sever a head when a single hit deals 25+ damage, or a called shot after bloodied (DM fiat). Each severed head removes one bite from Multiattack.

Reactive Heads. One reaction per head — usually opportunity attacks.

Wakeful. While it has at least 2 heads, it cannot be surprised.

Regrow (unless cauterized). At the end of its turn, if a head was severed since its last turn and the stump was not dealt fire or acid damage (or a club cauterizing strike), it grows two heads (max 8). Same gimmick family as other hydra set pieces in the library.

Arena Echo. Not Echidna's brood-mother fight — a staged labor-echo. Heracles absent.

Multiattack. The hydra makes as many bite attacks as it has heads (max 8).

Bite. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 10 (1d10 + 5) piercing.

Olive-Resin Club

Wondrous weapon (club), labor token

Appearance: A short olive-wood club sticky with dark Nemean resin; twelve notches cut into the haft.

Handout. "Not the hero's name — the sand's. Strike the hide, stake the charge, leave the legend empty."

Enc. 1–2. As a weapon: +1 club. Once per encounter, a hit ignores the Nemean Lion's Hide That Will Not Cut. Once during the Hydra wave, a hit with the club may be declared a cauterizing strike if a free hand holds flame (torch/cantrip): that stump does not regrow.

Enc. 3. Plant in the sand as an action (DC 14 Athletics or Strength). Until the start of your next turn, the Cretan Bull's next charge must target the stake or take 4d10 piercing and fall prone (no save). Once during the Boar wave, as a bonus action, plant briefly to grant allies advantage on the next shove/grapple against the boar.

👤

Archon Melanthios

Human stadium-lord, quest giver · Lawful Neutral

Appearance: Gold-dusted cloak, olive diadem, voice trained to carry over 10,000 throats.

Motivation. He will reopen the Labor Games only if living champions prove mortals still matter without demigods.

Secret. The beasts are arena-echoes of the Twelve — Melanthios forbids naming Heracles in the sand.

Hard rule. If the crowd chants the demigod's name for three rounds, Hera's omen-crows blot the sun and the finale becomes Deadly — break the chant first.


Encounter 2 — Gate II: Mares & Stymphalians

Medium–Hard · ~55–60 min · Waves 3–4 · Labors VIII & VI

Overview

Short rest (~10 min) before Gate II. Mares from the East chute; then a Stymphalian flock from the open sky (same bronze-beak threat as Stymphalian Storm). Thaleia is chained at the bit-rack during Wave 3.

🗺 Terrain

Oval · East chute · West pen lever · bit-rack · blood-slick difficult terrain · Wave 4: hanging bronze gongs (action: Performance/Athletics DC 14 to clang — flock disadvantage 1 round).

Wave A — Mares of Diomedes

  • 3 mares (Hard: 4). Free Thaleia to recruit (or vow to pen, not slaughter).
  • Skill path: drive 3 through West gate (shove / lariat / Animal Handling DC 16).
  • Mare reaches stands → Chant Clock +1.

Wave B — Stymphalian Flock

  • As written: 6 birds (Easy 4 / Hard 8). Flyby + Dive Bomb. Thunder/gongs impose disadvantage.
  • Skill path: 4 successes before 3 failures (Performance, Athletics gongs, Survival herding, Arcana weather DC 15) drives the flock into the West pen netting — ends the wave with half the remaining birds captured.
  • Thaleia nets: Ready vs dive. Combat win: reduce flock to ≤2 or force a scatter (all bloodied + one gong success).

Olive-Resin Club

Wondrous weapon (club), labor token

Appearance: A short olive-wood club sticky with dark Nemean resin; twelve notches cut into the haft.

Handout. "Not the hero's name — the sand's. Strike the hide, stake the charge, leave the legend empty."

Enc. 1–2. As a weapon: +1 club. Once per encounter, a hit ignores the Nemean Lion's Hide That Will Not Cut. Once during the Hydra wave, a hit with the club may be declared a cauterizing strike if a free hand holds flame (torch/cantrip): that stump does not regrow.

Enc. 3. Plant in the sand as an action (DC 14 Athletics or Strength). Until the start of your next turn, the Cretan Bull's next charge must target the stake or take 4d10 piercing and fall prone (no save). Once during the Boar wave, as a bonus action, plant briefly to grant allies advantage on the next shove/grapple against the boar.


Encounter 3 — Gate III: Boar & Bull (Boss)

Hard · ~60–65 min · Waves 5–6 · Labors IV & VII

Overview

Water and a cheer only — no full rest. Erymanthian Boar (Calydon-scale quarry energy, capture-preferred labor) then the Cretan Bull Hard finale.

🗺 Terrain

Cratered oval · South debris · pillar stubs · North pen + portcullis · sand-stake squares for the club.

Wave A — Erymanthian Boar

  • Charge + Relentless. Preferred win: capture/pen while bloodied (3× Athletics/Animal Handling DC 16 + portcullis).
  • Club: once, brief plant → advantage on next shove/grapple vs boar.
  • If the boar fight exceeds 5 rounds, Melanthios may release the Bull early (overlap — brutal).

Wave B — Cretan Bull (Boss)

  • Legendary actions. Charge / Sandstorm Bellow / Earth-Shatter Hooves.
  • WIN — MAGUFFIN: Plant Olive-Resin Club (action, DC 14). Next charge hits stake or 4d10 + prone.
  • Pen track while bloodied, or slay. Chant Clock 3: bull heals 40 once + extra legendary that round.
  • Portcullis or 0 HP → mortal olive crown; murals of the absent hero look away.
