Ichthyosauria is the region added by the Tides of Oblivion DLC, Jerold's story. It is by far the largest map: six areas, 11 elevators, five ladder kicks, 23 crates, 36 stair objects and nearly 200 regular enemy rows, mainly Gold Diggers, Venomous Impostors and Assassins. Its bosses are Guderian the Guardian, the Treasure Thieves and The First Fallen: Handel.
See Maps#The regions for all regions and Chapters#Ichthyosauria (DLC chapter 9) for this chapter's story.
Sub-areas and carriage stops#
Six areas (1 to 6). One extra stop is listed: Stonefin Shoal. Unlike the base chapters, the story table's AreaId column says 2 for this chapter, which does not match the six areas used by its spawn rows (inferred: it only names the starting area group).
Map entry: Ichthyosauria (site 900). In-game blurb: a short text about a sleeping monster under the sea and a river of souls (summarised).
| Stop | Site id | Opens when (quest) | Notes |
|---|---|---|---|
| Stonefin Shoal | 901 | quest 95163, quest 41001 | Jerold joins the party (ES_StoryDialog 94038); the boss Edith dies |
The scene itself contains 2 carriage point(s): point 1 (area 2, direction 2); point 2 (area 2, direction 2).
Altars#
Altars 1 to 5 complete quest 95191 once quest 95190 is done.
| Altar (save id) | Needs quest | Resting completes quest |
|---|---|---|
| 1 | 95190 | 95191 |
| 2 | 95190 | 95191 |
| 3 | 95190 | 95191 |
| 4 | 95190 | 95191 |

The five Heggies of this region:
| Frog id | Start mood | Gift that raises mood (+1) | Gift that lowers mood (-1) | Neutral gift | Gifts needed to finish | Cheapest total cost |
|---|---|---|---|---|---|---|
| 9129 (area 6) | 2 | 20 Sanity offered (costs 10) | 40 x Bone Fragment | 3 x Anthozoan Bones | 3 | 30 Sanity |
| 9130 (area 4) | 2 | 40 x Bone Fragment | 2 x Health Potion | 3 x Anthozoan Bones | 3 | 120 x Bone Fragment |

Hidden mechanics#
- Stonefin Shoal needs two flags. The stop requires both quest 95163 (Jerold joins) and quest 41001 (boss-mode exit). Every listed quest must be complete (stop-visibility code,
fs_savestory.lua), so you need both. - Two Heggie achievements. The 40 frog rows split by chapter: the 35 Heggies of chapters 1 to 7 count toward Naturalist (goal 35), and the 5 here count toward Dominator's Revelry (goal 5). Both goals need every Heggie of their group (Heggie offerings#Rewards).
- Pickups are re-rolled by journey. Items found only in journey 1: none. Items that only appear from a later journey on: none. Items whose total amount differs between journey 1 and journey 4: Big Bone (59 to 51), Blessed Antitoxin Potion (2 to 4), Blessed Elixir of Stamina (2 to 3), Blinding Smoke (4 to 6), Elixir of Health (1 to 3), Elixir of Recovery (2 to 3), Fractured Body (18 to 25), Huge Fang (13 to 15), Poison Awl (5 to 7), Sour Conifer Leaf (3 to 5), Wildfire (3 to 5). The columns that switch are explained in World mechanics#Scene pickups and the journey.
- No Dark Mist walls here. Rebounding black-fog walls exist only in chapters 1 to 5 (World mechanics#Walls).
New Game Plus and Arcade#
Enemy level range by journey over all placements, bosses included: journey 1 1-30, journey 2 1-50, journey 3 1-70, journey 4 1-89. The journey value is capped at 4 (BattleData.GameLoopMax = 4; see Maps#hm-enemy-levels-scale-by-journey-not-by-region).
This region has no Arcade copy. See New Game Plus for loop rules.
