In the demon-infested world of Shin Megami Tensei V: Vengeance, Mandrake Roots serve as vital quest items, particularly for the side mission known as “The Root of the Problem.” These roots, harvested from the eerie Mandrake demons, are essential for crafting potent medicines used by fairy allies. This guide provides an in-depth look at sourcing these items, from initial quest acceptance to delivery, while addressing challenges in both the original Canon of Creation and the expanded Canon of Vengeance paths.
Understanding Mandrake Roots and Their Lore
Mandrake Roots originate from Mandrake demons, mythical plant-like entities whose humanoid roots are prized in alchemy for healing potions. According to game lore, uprooting a Mandrake triggers a deadly scream capable of killing those nearby, adding a layer of peril to their acquisition. In SMT V Vengeance, these roots are not mere collectibles; they unlock interactions with fairy factions and yield combat advantages.
These demons typically appear around level 30, making them accessible mid-game but demanding preparation. Their weaknesses to fire skills make them vulnerable foes, yet accompanying enemies complicate hunts.
Quest Initiation: Starting The Root of the Problem
The quest activates in the Fairy Village within Shinagawa, post-completion of the “A Golden Opportunity” main quest but prior to “Go to Yuzuru’s Aid.” Locate Silkie, positioned near Oberon and Titania. She requests eight Mandrake Roots to restock her medicinal supplies, cautioning about nearby threats.
- Prerequisites: Progress through Shinagawa’s main story until Fairy Village unlocks.
- Acceptance Location: West of the Fairy Village Leyline Fount.
- Dialogue Trigger: Speak directly to Silkie for the quest log entry.
Accepting the quest spawns Mandrake encounters north of the village, transforming the area into a farming hotspot.
Prime Hunting Grounds: Shinagawa Fairy Village Area
From the Fairy Village leyline, venture north toward Gotenyama. Mandrakes populate this forested zone, often in small groups initially. Each defeat yields one root, necessitating at least eight battles.
| Location | Enemy Level | Key Weakness | Notes |
|---|---|---|---|
| North of Fairy Village (Gotenyama) | ~30 | Fire (Agilao) | Initial solo Mandrakes; escalates with Narcissus. |
| Shinjuku National Park (Alternate) | ~30 | Fire | Canon of Vengeance relocation option. |
Proximity to the leyline facilitates repeated runs, minimizing travel time between fights.
Combat Strategies: Defeating Mandrakes and Narcissus
Mandrakes succumb quickly to fire attacks like Agilao or Maragi. Stock demons with these skills—Jack Frost or Pixie variants work well early on. However, after securing the first two roots, Narcissus reinforcements join, starting with one, then two, and finally three per pack.
Narcissus employs Sexy Dance for charm ailments, disrupting party cohesion. Fortunately, they share Mandrake’s fire vulnerability. Prioritize fire bursts to clear adds swiftly.
- Party Setup: 2-3 fire users; include ailment cleansers like Patra.
- Tactics: Target Mandrake first for the root drop; use Magatsuhi for AoE fire if available.
- Ailment Mitigation: Equip accessories resisting charm or maintain Me Patra.
Encounters are unavoidable pairings, so endurance farming is key. Eight wins secure the quota without excess grinding.
Canon of Vengeance Specifics: Relocating Silkie
In the Canon of Vengeance route, delaying the quest past “Go to Yuzuru’s Aid” triggers a Fairy Village assault, dispersing Silkie. Quest progress persists, but delivery shifts to Shinjuku’s Da’at ward.
Head northwest from the Shinjuku Gyoen leyline, near demon NPCs and a Magatsu Rail. Silkie awaits there immediately upon map entry, streamlining completion. This adjustment preserves rewards without penalties.
Quest Rewards and Long-Term Value
Delivering eight roots grants 6,000 EXP for the party and the Fairy Talisman. This accessory empowers Fairy demons with Fairy Banquet, a potent Magatsuhi buff enhancing team performance.
Repeat deliveries aren’t specified here, but similar quests offer ongoing gems—check Silkie post-completion. The talisman shines in Fairy-heavy builds, amplifying buffs in boss fights.
Additional Mandrake Encounters Across SMT V Vengeance
Beyond the quest, Mandrakes feature in other content:
- Mita Abscess: Triple Mandrake miniboss blocking Tokyo Tower path.
- Shiba Park Subquest: “Pollution Panic”—defeat five Azumi for Yoma Talisman.
- Shinjuku National Park: Random spawns teach skills like Shibaboo and Patra.
These bolster root farming if quest stock runs low.
Optimizing Your Hunt: Tips and Builds
Recommended Demons
| Demon | Level | Key Skills | Role |
|---|---|---|---|
| Oni | 25+ | Agilao, Tarukaja | DPS + Buffer |

Farming Efficiency
- Leyline Reloading: Fast travel to reset spawns.
- Essence Farming: Fuse fire essences for broader coverage.
- Incense: Boost EXP/Macca for quicker leveling.
Avoid overleveling—level 30 party suffices.
Common Pitfalls and Troubleshooting
- Missed Village: In Vengeance, proceed to Shinjuku promptly.
- No Drops: Confirm Mandrake defeat; roots auto-collect.
- Escalating Foes: Stock anti-ailment tools early.
- Quest Lockout: Complete before advancing main story if possible.
Broader Context: Mandrakes in Megami Tensei Series
Mandrakes recur across titles, from Strange Journey’s screaming lore to Persona 5’s Death Arcana role with Pulinpa and Energy Drop. In SMT V, they teach Poisma and Shibaboo, enriching fusion options. Vengeance expands their utility via new routes.
