Filro

Filro the Forgotten is a hostile male Drow Wizard located in the Dread Hollow area of the Underdark. Can be spoken to with  Speak with Dead.

Overview

Filro fights alongside the Hook Horrors that patrol around the Sussur Tree. Filro holds the Icy Crystal, one of the three pieces required to rebuild the powerful Mourning Frost.

History

Xargrim, Filro, and Dhourn were trying to find the Adamantine Forge somewhere within the Underdark. Filro was tasked with learning about any defense mechanisms within the forge and learned of a guardian of the forge that could be injured while it was in magma, and that was vulnerable to a "hot hammer".

Abandoned by his companions after they turned on each other, Filro was found by a pack of Hook Horrors who took him in and cared for him.

Speak with Dead

When the spell is used, the talking party member must pass a DC 20 Deception check as the mad Drow will accuse the party of killing their 'beloved'. Failure will have him refusing to talk. If successful, it's possible ask questions normally.

Party member: Who are you?

• Filro: FIlro... forgotten... forsaken...

Party member: You lived among these creatures?

• Filro: My pack... found me... fed me... gnome flesh...

Party member: How did you come to be here?

• Filro: Chasing... mystery... riddle... lie... the Adamantine Forge...
  • Party member: The Adamantine Forge - what is that?
    • Filro: Workshop... of great Silouv... Yali...
    • Filro: Artefacts... beyond price...
  • Party member: Where would I find this forge?
    • Filro: Location... was Dhourn's task... I learned... of the Guardian...
      • Party member: What's the 'Guardian'?
        • Filro: Protector... of the Adamantine Forge...
        • Filro: Born... from hellish heat... in hellish heat... destroyed...
  • Party member: Who is this Dhourn your records mention?
    • Filro: Friend... enemy... like Xargrim

Party member: The glowing tree - what is it?

• Filro: It... stills the Weave... protects me from... the others...
  • Party member: What others?
    • Filro: Xargrim... Dhourn...
    • Filro: Three seek... Adamantine Forge... only one of us... may find...

Encounter details

Filro will use the the height advantage he has among the cliffs and roots to throw down debilitating spells onto intruders for the monstrosities to pick off. He favors casting  Tasha's Hideous Laughter to make his enemies fall  Prone, leaving them open for a Hook Horror's deadly  Multiattack (Hook Horror). Grouping up near him on the high ground can also lead to a lethal outcome if he uses his  Thunderwave to knock party members off the cliff.

If the Bulette is still alive when the party begins the fight with Filro and the Hook Horrors, then it has a chance of burrowing out of the ground to join the combat. Its  Territorial passive leads to it attacking the Hook Horrors before going after the party.

Tactics

Filro has low Wisdom and Charisma, making him weak to spells with such Saving Throws. A well aimed  Shove can also instantly kill him via fall damage or by knocking him into a chasm, though in the latter case you risk losing the Icy Crystal he carries.

The party can also consider not fighting the Bulette until it makes its appearance during this fight. The Bulette and Hook Horrors will deal good damage to each other, potentially weakening all of them enough for the party to kill them.

Also, if Sovereign Glut is a follower, he can use his Animating Spores ability to revive a Hook Horror as a "Spore Servant", letting you use their powerful natural abilities against the other Horrors and the insane wizard.

Notes

• If you kill Filro before encountering Dhourn, you may tell Dhourn that you killed Filro in place of discussing the Adamantine Forge. If you successfully deceive Dhourn that Filro had nothing of note, you may avoid combat with Dhourn entirely (or at least get an opportunity to position yourself for the fight.)
