Walkthrough

The Secluded Cove is north-east of the druidic ritual circle in the Emerald Grove. Upon approach, strange singing can be heard at X: 271 Y: 523. Near the water, a child Mirkon is enchanted by the singing of harpies X: 327 Y: 549. The party can try to focus on the singing or tell Mirkon to return to shore.

If the party focus on the singing, they can try to resist the song:

• [WISDOM] Struggle against the music's pull. (DC 5)
• [WISDOM] Struggle against the music's pull. (DC 5 ) (if passive DC 10 Nature roll passed)
• [DRACONIC BLOODLINE] [CHARISMA] Foul creatures - mere carrion birds compared to your bloodline. Focus the will of the dragon against their song. (DC 5)
• [SORCERER] [CHARISMA] Focus your will. Improvise a magical shell to dampen the music. (DC 5)
• [BARD] [PERFORMANCE] Focus by singing: 'There once was a lady who met with a merrow, and tried to disclose it to her foolish fellow...' (DC 5)

If the party successfully resist the song, they can attempt to overpower or distract Mirkon:

• [BARD] [PERFORMANCE] Focus by singing: 'There once was a lady who met with a merrow, and tried to disclose it to her foolish fellow...' (DC 5)
• [BARD] [PERFORMANCE]  '... Her man would not listen, he thought it tall tales, until he rubbed up against all of her scales!'  (DC 10 )
• [BERSERKER] [PERFORMANCE] ROAR. OVER. THE VOICE. (DC 10 )
• [BARBARIAN] [PERFORMANCE] Drown out the harpies with a ROAR. (DC 10 )

Regardless of what the party tells Mirkon, he attempts to move closer to the harpies.

The harpies utilize a combination of the terrain and their  Luring Song to bring Mirkon and the party into close range. One harpy always remains at a distance to perform the song, which can cause party members to waste their combat turns if they fail to resist. Meanwhile, the other harpies fly close to attack the party. Any attempts to approach distant harpies will be slowed because of the area's Difficult Terrain. The harpies can  Fly over the distance and terrain, which allows them to easily  Multiattack.

It is recommended to use ranged attacks and spells on the singing harpy to break their Concentration. If successful, it is suggested to fight aggressively before another harpy sings again.

In preparation for combat, it is possible to  bless the party before speaking with Mirkon to improve the party's resistance to Luring Song. Using gnomes, elves, or half-elf characters with Advantage on saves can improve the likelihood of resisting the song. It may also be helpful to utilize the high ground flanking Mirkon.

A viable yet violent strategy to protect Mirkon involves throwing or shoving him away from the shoreline and the harpies. Tossing him provides more distance from the enemies to reduce his likelihood of being killed.

A party member can cast  Calm Emotions to protect Mirkon and all party members within its casting radius from being affected by Luring Song, which significantly reduces combat difficulty. (The game log will still show a saving throw being rolled, but the characters are unaffected on failures.) Alternatively, the party can use  Silence and keep their entire party within the silenced area. In both cases, the party should be careful to prevent the caster's Concentration from being broken. If the party member casting Calm Emotions or Silence is a cleric, they can cast  Sanctuary on themselves to prevent broken Concentration.

However, note that casting Silence over Mirkon before speaking with him immediately triggers the fight and skips all dialogue. If the player character decides on this strategy, it is advised to cast Silence over Mirkon and the entire party.

Once the harpies are defeated, Mirkon informs the party that he needs to get back because Mol will be mad at him. Before leaving, he tells them to find Doni and tell him that they want to see the "Dragon's Lair".

If the party trigger this quest and long rest, Mirkon will die. Mirkon will also die if the party resolve  Save the Refugees by completing the Rite of Thorns or evading the goblin attack.

Quest rewards

• Entrance into the tiefling children's hideout, the "Dragon's Lair"

Notes

• This quest is triggered when crossing X: 299 Y: 542.
• Helping Mirkon is an easy way to gain favor with Mol and initiate  Steal the Sacred Idol.
• Saving Mirkon grants Slaying the Piper for the urchin background.
• Although he has no notable possessions, pickpocketing Mirkon while he is entranced will grant The Allure of Coin for the criminal background.
• Long rests will not fail the quest after discovery.
• Killing the three goblin leaders before completing this quest will result in its failure.
• The bard's ability to use Performance against the harpies is a reference to the bard's ability in past editions called "Counter Song".
• While talking to Mirkon, using Improvised Melee Weapon with another character and moving him away from the beach actually breaks him from the harpies' trance and completes the quest without requiring to fight them. The harpies will be revealed in the map after that.
