Welcome to Elderfield School Guide — Elderfield High
Last updated: 2026-09-27 · 8 min read
Elderfield High is the school the game never points you at. It opens late, it sits east of town rather than in it, and the three school scenarios inside it are the whole requirement for Ghost Hunter — a completionist achievement most players never touch. The school's own enemies punish a single damage type, and the Lost children flip into a second, meaner state halfway through the fight.
Elderfield High is in the Town Outskirts (East). It contains three school scenarios, and completing all three unlocks "Ghost Hunter" — a 0.1% achievement — effectively completionist tier. The school's own enemy roster is Teacher's Pet (Insight element, weak to Darkness) and the Lost Schoolboy and Lost Schoolgirl (Curse element, weak to Insight, and both of which flip into an Enraged state mid-fight with higher stats). Bring both a Darkness weapon and an Insight skill — the school is built to punish having only one damage type.
Where the School Is

The school sits in the Town Outskirts, on the East side — the same outer ring of town that holds the Workshop and the Beginner Mine on its west side and Tanner's Cabin and the Old Woods entrance to the north. If you have found the Workshop, you have already been through the area the school is attached to.
Access is not a key or a purchase. A letter from Edwin about the school is what opens the area up, and finding the next step after that is where people stall: the school has no puzzle layer to solve, so an unresolved objective can turn into two in-game days of walking the grounds looking for a trigger that does not exist. If you are holding an unresolved school objective, enter every room you can and interact with everything.
| Getting there | Detail |
|---|---|
| Region | Town Outskirts (East) |
| Trigger | A letter from Edwin about the school |
| Nearest fast travel | The Town (North) bus stop is the north-side unlock at 200 Gold. The Town (West) stop (50 Wood) cuts across to the Library and the western side |
| Recommended point in the run | Late. The achievement is 0.1% — this is not an area to attempt while your gear is still on the Stone rung |
The Three School Scenarios
The achievement text is explicit: "Ghost Hunter — Complete all 3 school scenarios in Elderfield High." That gives the objective a hard shape even though the individual steps are not spelled out in-game.
| Achievement | Requirement | Global completion | Type |
|---|---|---|---|
| Ghost Hunter | Complete all 3 school scenarios in Elderfield High | 0.1% | Exploration |
| Snooping Around | Slay the Hall Monitor | 30.4% | Combat |
The Hall Monitor is an Insight-element enemy fought in the Mall F1 Hallway, not at Elderfield High — it is a school-themed enemy that lives in the Mall. "Snooping Around" is therefore a Mall achievement, not a school one, and it sits at a far more common 30.4% completion. If you have been searching the school for it, that is the mistake. The Mall side is covered in the Mall guide.
The School Enemy Roster
Three enemies are found at the school. All three are built around the game's element triangle, and all three are unfriendly to a player who has only invested in one damage type.
| Enemy | Element | Weak to | Level range | Notable drops |
|---|---|---|---|---|
| Teacher's Pet | Insight | Darkness | LV3–LV4 | Cleansing Balm, Mystery Steak, Bloody Skin, Apple (rare), Viscera |
| Lost Schoolboy | Curse | Insight | LV1–LV4, plus an Enraged state | Dreampearl Seed, Crushed Bones, Bloody Skin, Viscera, Mysterious Ooze |
| Lost Schoolgirl | Curse | Insight | LV1–LV4, plus an Enraged state | Extra Pouch, Crushed Bones, Gem Bag, Bloody Skin, Mysterious Ooze |
Teacher's Pet — the Insight problem
| Stat | LV3 | LV4 |
|---|---|---|
| Max HP | 300 | 350 |
| Defense | 40 | 60 |
| Magic Defense | 40 | 60 |
| Attack | 32 | 46 |
| Magic Attack | 32 | 46 |
| Agility | 60 | 75 |
Look at the Agility. At 60 to 75 it is the stat that matters most, because in this game turn order and action points decide how much happens per round — a 75-Agility enemy is acting early and often. The 300-to-350 health pool combined with 40-to-60 in both defence stats means this is a genuine damage check rather than a speed bump, and the Darkness weakness is the answer: a Blade or Staff of Darkness converts a long fight into a short one. What to forge and in what order is in the forging guide.
Teacher's Pet also drops Apple rarely, which matters more than it looks — see the cross-system note below.
Why the School's Lost Children Get Tougher Mid-Fight
The Lost Schoolboy and Lost Schoolgirl share the same HP and Agility envelope and differ mainly in whether they lean physical or magical. Both have a second state — Enraged — with strictly better numbers, which is why a fight that looked under control can turn in the middle.
| Stat | LV1 | LV1 Enraged | LV2 | LV2 Enraged | LV3 | LV3 Enraged | LV4 | LV4 Enraged |
|---|---|---|---|---|---|---|---|---|
| Max HP | 25 | 25 | 75 | 100 | 75 | 100 | 125 | 150 |
| Defense | 11 | 13 | 15 | 20 | 38 | 45 | 55 | 60 |
| Magic Defense | 11 | 13 | 15 | 20 | 38 | 45 | 55 | 60 |
| Agility | 9 | 9 | 20 | 20 | 60 | 60 | 75 | 75 |
The pattern to plan against: the enrage adds HP and both defence stats, and it does not slow them down. Agility is identical in and out of the enraged state, so you do not get a turn-order reprieve for the tougher phase — you simply have to out-damage a bigger pool at the same speed. On a level 4 Lost Schoolboy that is 25 extra HP and 5 points in each defence; on a level 2 it is the largest relative jump (75 to 100 HP plus 5 in each defence), which makes the lower-levelled children the more swingy fights in percentage terms.
Their Attack and Magic Attack values diverge, so knowing which one you are facing helps: the Schoolboy leans physical, the Schoolgirl leans magical. That decides whether you want physical or magical mitigation up before the enrage lands.
What to Bring to the School
The school is a late-game area with a late-game element spread, so preparation is mostly about damage types and sustain:
- A Darkness weapon. Teacher's Pet is the only Insight-element enemy in the school and it is also the tankiest. A Blade or Staff of Darkness is the difference between a fight and a grind.
- An Insight source for the Lost children. Both are Curse element and both are weak to Insight. If your build has no Insight answer at all, the two Lost fights are where you will notice.
- Sustain, not burst. Teacher's Pet has 350 HP at LV4 with 60 in both defences. Bring cooked meals rather than relying on healing skills, because food also covers the turns you spend not attacking.
- Something for the enrage. Because Agility does not change when the Lost children enrage, plan the second phase as a fresh damage race rather than assuming you can burst them down.
- Cleansing Balm if you have it. It is a Teacher's Pet drop, which is a strong hint that the fight can inflict something you will want to clear — see blessings and curses for what the game's status effects actually do.
How the School Feeds Other Systems
The school is not a self-contained side area, and the clearest proof is a single item: the Apple. It is a rare drop from Teacher's Pet, and it is also one of the six items required by the Orange Room's "Unique Enemy Drops" painting in the Art Gallery. Two separate systems, one item, one specific enemy.
That matters because the Art Gallery achievement track is one of the other 0.1% completionist checks in the game, and the Orange Room's Adventure paintings are the hardest of the six rooms precisely because they are assembled from drops that live behind specific enemies and events. If you are working on Art Restoration or Supporting Arts & Culture, Elderfield High is on your supply route. The full room-by-room breakdown is in the Art Gallery guide.
The other cross-link is the achievement list itself. Ghost Hunter sits in the same collection tier as "the full Art Gallery" and "all 3 school scenarios" — the achievements guide groups those together for a reason: they are the completionist checks with no partial credit, so they are best attempted once your combat and economy side is genuinely finished.
Troubleshooting
Most school problems are placement and damage-type mistakes rather than bugs.
| Problem | Cause | Fix |
|---|---|---|
| Cannot find the school | It is in the Town Outskirts (East), not in Town itself | Head east out of Town into the Outskirts; the west side of the Outskirts is the Workshop and Beginner Mine |
| The school objective does not advance | The scenarios have no puzzle layer to solve | Enter every room and interact with everything, rather than hunting for a hidden trigger |
| Cannot find the Hall Monitor | It is not at the school | It is in the Mall F1 Hallway. See the Mall guide |
| Teacher's Pet is taking forever to kill | 350 HP at LV4 with 40–60 in both defences | Exploit the Darkness weakness. An Insight or neutral weapon turns this into a long fight |
| A Lost child suddenly got harder | The enrage state adds HP and both defences | Agility does not change when they enrage, so treat the second phase as a fresh damage race |
| Unclear which achievement the school belongs to | The school's achievement is Ghost Hunter, not Snooping Around | It is the 0.1% "complete all 3 school scenarios" entry; Snooping Around is the Hall Monitor's Mall achievement |
| Looking for an Apple | It is a rare drop from Teacher's Pet | It is also required for the Art Gallery's Orange Room — see the Art Gallery guide |
| Deciding whether the school is worth the trip | It is a 0.1% completionist check with a unique drop route | Do it last, after combat and economy are settled |
