Quests linked to the Ancestral Domain
Three quests involve the Ancestral Treechnid: Munster Makes the Mystery Less Mysterious, A Hysterical Judge, of which it is the first step, and Vengeance by Proxy for Bontarians. Accept them before entering: a fight won without the quest in progress doesn't count.
Head to the heart of the Domain, then defeat its master. After the preparations at Hel Munster's, defeat the Ancestral Treechnid in a single fight, talk to it, then join Silvosse.

The 5 rooms of the Ancestral Domain
Four fights against the Dark Treechnidians, then the Ancestral Treechnid. Their summons quickly clutter the map: keep escape lines open. For each room: the scenery, then the tactical view with the starting cells (blue: you, red: the monsters). Tap an image to enlarge it.

Defeat the Ancestral Treechnid
Every AP spent has a price
Paralysing Branch poisons its target for three turns: at the end of each of its turns, it takes damage for each AP used. The effect can be dispelled. Otherwise, play short turns with the affected character.

It has 53% resistance to Earth, Water and Neutral, but -5% to Fire and Air. Sylvan Bite removes 2 AP and 100 power at 2 RNG, Paralysing Branch punishes your AP up to 8 RNG. It summons a Major Arachnee from turn 3 and heals itself from turn 4.
Sylvan BiteUp to 2 RNG without line of sight: -2 AP for one turn and -100 power for two turns.
Paralysing BranchEnd-of-turn poison, three turns: damage for each AP used. It can be dispelled, up to 8 RNG, once per target.
Summoning of Major ArachneeFrom turn 3, cooldown of 5 turns: a Major Arachnee near him.
Treechnidian RegenerationHeals itself, from turn 4 for the boss, cooldown of 5 turns. The Venerable has it too.
The four-step strategy against the Ancestral Treechnid
Fire and Air. Its only two weaknesses. Build your damage turns around these elements: with anything else, it takes less than half of your hits.
Stay beyond 2 RNG. Sylvan Bite reaches 2 RNG, even without line of sight, and costs you 2 AP and 100 power for two turns. Hit him from farther away and spread your characters out.
Dispel Paralysing Branch. The poison doesn't stack, but lasts three turns and reaches up to 8 RNG. Dispel the affected character, or have them spend only the essential AP.
Summons and healing. From turn 3, it summons a Major Arachnee, and from turn 4 it heals itself, each time with a five-turn cooldown. Keep steady pressure on it and clear away summons that block your lines.
The monsters of the Ancestral Domain
Four level 74 to 82 Dark Treechnidians, which remove AP and MP and summon relentlessly. Earth and Water against the Dark Treechnee and the Arachnotron, Fire against the Dark Treechnid. Resistances in red are their weaknesses.
In which order to kill the monsters
- Venerable Treechnid — it removes 3 AP in contact, 2 MP at short range, and heals itself.
- Arachnotron — its Complicity spell gives it power, range and critical, and it removes MP from afar.
- Dark Treechnee — it teleports onto you and reduces your resistances.
- Dark Treechnid — it hits from afar and locks you with its summons.

Preparing your run through the Ancestral Domain
A level 80 to 90 dungeon for teams that hit in Fire or Air and can handle AP removal. People come for the quests, the Ancestral Treechnid Roots and the boss's soul, required by the Ochre Dofus: plan for a Soul Stone for Average Souls (captures up to level 100).
How to enter the Ancestral Domain
The entrance is in the Dark Forest, in the Treechnid Forest, at : talk to Kikat Trunky to enter, and again to leave. The nearest zaap is the one at Crackler Mountain . You need an Ancestral Domain Key (consumed), the key ring, or the automatic group search.
Crafting the Ancestral Domain Key
It is crafted at a handyman. Four ingredients drop from the dungeon's monsters, at nearly 40%: Dark Treechnid Root, Venerable Treechnid Root, Dark Treechnee Bark and Stale Meat. Kralove (fishing), Freyesque Orchid and Flax (harvesting) complete the recipe.

Which team to bring against the Ancestral Treechnid
Fire and Air. The boss resists Earth, Water and Neutral by 53%. At least two Fire or Air characters shorten the fight considerably.
Dispelling and range. Paralysing Branch can be dispelled, and Sylvan Bite only reaches 2 RNG. A team that plays at range and dispels takes very little from the boss.
The comfortable classes. Classes that hit in Fire or Air at range are the most comfortable; a dispeller clears Paralysing Branch.
The five achievements of the Ancestral Domain
Each achievement rewards 2,853,000 XP and 2 Ancestral Treechnid Root, Duo doubles the XP. Special and Duo are both played at range: do them in the same fight.
| Achievements | Condition | Points | XP |
|---|---|---|---|
| Defeat the Ancestral Treechnid in this boss's dungeon. | 10 | 2 853 000 | |
| Defeat the Ancestral Treechnid in its dungeon while completing the “Nomad” challenge. | 10 | 2 853 000 | |
| Defeat the Ancestral Treechnid in its dungeon while completing the “First” challenge. | 10 | 2 853 000 | |
| Defeat the Ancestral Treechnid in its dungeon while completing the “Duo” challenge. | 20 | 5 706 000 | |
| Defeat the Ancestral Treechnid in its dungeon while completing the “Respectful Distance” challenge. | 10 | 2 853 000 |
Special: Respectful Distance
No enemy may be within 3 cells or less of an ally when it deals damage. Stay away from all enemies, summons included: Spimushes, Major Arachnee and Trunknids count. Check positions before each attack, and beware of the Dark Treechnee's and the Arachnotron's teleports.
First
The Ancestral Treechnid must be finished off first. Focus your Fire and Air attacks on it from the start. No summon or weakened monster may die before it: watch out for area damage.
Nomad
Use all your MP every turn; partial dodge makes it fail. Plan your movement before your spells. Avoid ending up stuck to the Trunknids and Sticky Trees: a partial dodge would make the challenge fail.
Duo
Two characters maximum, fewer than 20 turns. Two characters that hit in Fire or Air at range. Remove the summons that block your lines, without needless detours.
Drops and loot of the Ancestral Domain

Capturing the soul of the Ancestral Treechnid
