The Hypogean Oracle Review Post-Mortem

 The judging period for the Adventure Site Contest III is officially over, so it’s time for a post-mortem on my entry, The Hypogean Oracle.

There are five official judges in this contest. Unfortunately, I can only link to two reviews. Owen Edwards and Grutzi at Tiny Pink Tentacle just didn’t get to my entry in time. No shade on them, there were just a lot of entries this year. JB at B/X Blackrazor apparently has a beef with ACKS and phoned in his reviews of the ACKS entries. Worse, his review of my entry was literally just him abusing the Lord’s name. I’m not linking to it and I recommend praying for him.


The remaining two reviewers wrote very good, insightful reviews. Ben Gibson’s is here, and Shocktohp’s is here. I’ll go through my takeaways from both at the same time.


The Good


The Hypogean Oracle

Both Ben and Shocktohp enjoyed the titular magic item. I was worried reviewers would find it a bit verbose - it takes up a fair amount of space with its custom spell effect.


Story Web + Random Encounter Compatibility

Shocktohp liked the inclusion of story web connections. Both reviewers appreciated the option of dropping in randomly or placing ahead of time with rumors. For me, this was a big part of how I wanted to make the site valuable for real GMs. With the flexibility to seed it into your sandbox in an area where you can use rumors to point to it, or to use it to cover random encounters, the site can be useful in more campaigns.


Regular Good Stuff

Ben notes the map flow with multiple exploration options, and interesting monster interactions.


The Bad


Pushing the Page Limit

I received the frowny-face of Commodore for putting the random encounter table and Hag repertoire on the map page. In my defence, even some previous years’ winners put encounter tables and extra fiddly stuff on their map pages (see for example Etta Capp’s Cottage and Lipply’s Tavern from ASC I). Maybe the repertoire was pushing it.


Level Range

Shocktohp had two major complaints and this was the first one. I didn’t give a level range, and he said it wasn’t clear when/where players are supposed to encounter it. A second part of this complaint is that the Oracle would be more useful around levels 4-6 when clearing wilderness, but hags are very tough for characters of that level range.


I didn’t give a level range because I don’t use them. Hag lairs come up on the wilderness encounter tables in ACKS. When you travel the outlands, you can run into a hag lair whether you’re level 4 or 14, and per MM, hag lairs always contain 3 hags. I also think the danger level of the site is pretty well telegraphed by the 8HD galdrtre at the entrance.


Now if we’re following the JJ setting construction guidelines, we roughly divide sites into low, medium and high levels. In that framework, this would probably be considered a high-level site. I could’ve labelled it as such.


The criticism about the oracle being more valuable at mid levels is valid. One caveat though is that the oracle can discover underground locations. These might not be normal wilderness locations. They could easily be locations missed during the process of clearing the wilderness because they’re dormant. They could be parts of the underdark or mythic underworld totally unsuited to mid-level play. Obviously setting dependent, but I wouldn’t write it off at high levels.


Expected Treasure Value

Shocktohp’s second complaint was that the treasure value is kind of light, and he is definitely correct. He added it up and got 16,500, which is exactly right if you don’t count the very heavy workshop equipment. That stuff is worth another 10k but isn’t easily portable.


Harder to directly value is the regrowing crystal. ACKS being the greatest TTRPG ever made, of course there is a correct answer to the present value of 500gp per month given the game economy’s assumed interest rate of 3% per month (yes of course I’m serious, it’s in the Judge’s Journal Appendix E: Economics). The math is just 500 / 0.03 = 16,667gp.


Total monster xp is right around 10,000, so the rough expected treasure value is 40,000gp. And if you include the cheesy justification above, there’s 43,167gp of treasure. But yes, including the future value of components is a bit of a stretch, so I could easily add ~15,000gp of treasure to this site.


Of course another solution would be to reduce the lair to a single hag. It neatly solves both Shocktohp’s complaints, with the only downside being that it doesn’t fit the criteria of an MM hag lair.


Weak Helpers

Shocktohp pointed out that the potential help from the galdrtre and cave bear are not likely to be very useful, since hags can deal with a cave bear with a single spell, and a galdrtre is too big to enter the dungeon. I’d push back on this a bit. A spell that turns a cave bear to dust isn’t turning a PC to dust after all, and that character is also potentially useful as a source of information or a future henchman. The galdrtre can’t enter the basement, but it can provide information, and can deal with hags outside, potentially ambushing them with the PCs.


Yes, most players slaughter the bear and fight the tree, but that’s ok, the option is there. I don’t think I’d change anything here.


Oracle Missing Apparent Value

Yep, just a mistake on my part.


Hags Missing Spells

Shocktohp notes that the hags don’t have Rune of Warding or Illumination, Perpetual in their repertoires. This was intentional and I think it makes sense. As witches, hags are studious spellcasters, and they can swap out those spells after casting them. Unless I’m missing something (very possible) there’s no requirement to keep a perpetual spell in the caster’s repertoire in order to maintain it.


Coming Revisions

With all this considered, a v2 for this site is planned, with the following minor revisions:

  • Add magic item apparent value

  • Add map scale

  • Increase treasure values

Adventure Site Contest III: All ACKS Entries

As mentioned on this blog back in January, Ben Gibson has been running the Adventure Site Contest III and this year has seen a high number of quality ACKS II entries, including (if I do say so myself) my entry The Hypogean Oracle.

There was a request over at the Autarch discord to compile all the ACKS entries, so I've taken a pass over them and compiled this list.

I may have missed one or more, and there may also be more to come. I'll update as that comes to light!

Dark Age of Eracost Session 29

 From my perspective, playing Fingol.

Party

  • Baron Fingol Innes, Navgarine Keeper of the Stars 5

    • Kilosz the Cataphract, Fighter 4

    • Tavenna, Navgarine Keeper of the Stars 3

    • Ranenno, Navgarine Forester-Bard 2

  • Karmrakir, Tratkean Thief 4

    • Nalin, Assassin 3

    • Gregosz, Fighter 2

    • Uomir, Fighter 2

    • Szaldar, Keudan Priest 2

    • Runor, Venturer 2

  • Frannoc Dreiwan, Navgarine Agent 3

    • Llewyn, Lynx 1

Summary

Nearly two weeks of downtime passed, with Fingol and Frannoc travelling to Rantal, and Karmrakir taking ship to various Navgarine towns.


The party delved deeper into the Talbruin tin mine, battled more Attercops and recovered a couple of magic items.

Recap

Nov 6, 427


After leaving the mines with a decent prize of coin, Fingol was eager to travel to Rantal. Ravenna would soon be finishing her task of gathering rare books, and it was about time to expand the mercenary force in a bigger market.


Ranenno had business of his own there, so the two set out with Llewyn, and Fingol’s expeditionary force. Karm had (probably very illegal) business of his own in Talbruin, but graciously (shockingly?) lent us his venturer henchman Runor.


Nov 8


Fingol put out postings for henchmen and mercenaries, and Runor sold off the two potions from the tin mine. While Frannoc went about his own business, Fingol studied Spellward, finally finishing it on the 11th.


Frannoc asked Fingol pointedly about natural power, and took a great interest in the technique for dispelling natural power. So much so, he purchased the formula for a potion of dispel natural power from the School of the Ebony Sun. He gave it to Fingol along with a 400gp contribution toward the improvement of the alchemy lab.


To that end, since buying of alchemy tools was going very slowly, Frannoc and Fingol decided to import some additional tools.


Nov 14


Hirelings reported to Fingol, and negotiations went disastrously. Although all the potential recruits had heard of Fingol’s exploits, the impression upon meeting him in person was apparently underwhelming. Nine heavy spearmen were recruited, but crossbowmen and a priest refused offers.


The final applicant was a familiar face… Sapporobir Caan! Although he had cut ties with the party, he drunkenly stumbled into Fingol’s recruitment and applied. This negotiation also went south when Sapporo remembered that he’d have to work with Karmrakir again if he joined.


Nov 15


With city business complete, the party set off, leaving Iahzir in charge of finishing the tool acquisitions. They returned to Vigilant Keep and left the wagon and goods, then set off back to Talbruin.


Nov 18


Re-entered the tin mines.


Down on the second level, two groups of attercops were slain, and some treasure recovered, including a sword +1, watchful.

Strategic Overview

Fingol’s Goals

Immediate

  • Grow the domain of Vigilant Keep

  • Find the properties of the Staff of Ninavar

  • Find Ierocain

  • Settle the score with the Nimonuin Trade Guild

  • Overthrow Lord Priest Ilmevon of Talbruin

  • Learn more of the monster-siphoning magic used by Ierocain

The Hypogean Oracle


I've been in the midst of a couple large ACKS projects - on one hand rebooting the sandbox for my home game, and on the other working on a large adventure site. That site is a multi-level manor house with a big dungeon beneath and lots of custom stuff. But I wanted to slip in a small project too, so I'm not going forever without finishing something.

To that end, last month I put together an entry in the Adventure Site Contest III, run by Ben Gibson at Coldlight Press.

It's a small, high-level wilderness lair based around a mash-up of ideas my wife and I had. I wanted to do an earth elemental-themed location, and Brooke suggested an observatory. So, I combined these ideas into a magic item that acts as an underground observatory, allowing a user to find nearby dungeons. The rest of the location grew organically from thinking about where such an item could be found.

Ben's review of the site is already up, and others should be coming soon from the other reviewers.

For anyone following along the contest who wants to see the full details, you can download it from google drive.

If you like it and want to support my goal of making tens of dollars publishing RPG content, it is now available on DriveThru RPG (pay what you want).

Dark Age of Eracost Session 28

From my perspective playing Fingol.

Party

  • Baron Fingol Innes, Navgarine Keeper of the Stars 5

    • Ranenno, Navgarine Forester-Bard 2

  • Karmrakir, Tratkean Thief 4

    • Nalin, Assassin 3

    • Gregosz, Fighter 2

    • Uomir, Fighter 2

    • Szaldar, Keudan Priest 2

    • Runor, Venturer 2

  • Frannoc Dreiwan, Navgarine Agent 3

    • Llewyn, Lynx 1

Summary

The party collected their pay and gained some measure of favor from the Lord Priest Ilmevon of Talbruin by delivering proof of the beastmen and attercop found in the tin mines. After two days' rest we delved again and encountered some men from the rifts.

Recap

Nov 3


“Beastmen and worse, my Lord Priest.”


Ranenno displayed the string of hobgoblin heads, and Karmrakir the head of the hideous attercop.


This time, Lord Priest Ilmevon (formerly transcribed as Ilmanar) was more subdued. Faced with proof of his mistake, he asked for time to consider his next move, and paid us a month’s wages. Asked about the attercop’s claim to be there for “vengeance”, he had no idea. Asked about the possibility of Gadaszin being beneath our feet, he gave a non-answer.


Although he was no longer hostile, his lazy answers and request for a month to think about what to do about the mine continued to convince us of Ilmevon’s incompetence. We also needed funds beyond just a month’s merc wages, so we decided to return to the mine again and get to the bottom of it. The foreman had promised us whatever loot we could find beyond their tin ingots.


The next two days were spent resting and engaging in some rumormongering, buying and selling. Fingol continued to study his book of Spellward (5/7).


Rumors:

  • An assigner cult has arisen in Zel Charakt.

  • An old man arrived in Talbruin, stared into the sea, and then set off in a boat and never returned.

  • The corruption of Gadaszin appears to be pulling back from the Final Wall!

  • A keeper from Navgarine was seen in Talbruin.

  • The Duke’s expedition to Zel Charakt failed. Now there will be a war!


Nov 6


Explored the mines without splitting the party this time.


Slew a group of gnolls and proceeded to the lower level. Frannoc, scouting alone, spotted some men with the glass-like appearance of men from the Rifts. He snuck away without being seen.


We arrived in force and engaged them with lightning, slaying all but one. Frannoc chased the man and convinced him to parley. He spoke in Ancient Aramat, which the priest Szaldar and Fingol were both well familiar with. The man’s name was Saulos. We questioned him, but he remained very tight-lipped. He revealed that his group had been searching for two others of their kind, but would not reveal his greater mission or the name of his master. He offered two small onyx gems in exchange for his life, but Fingol demanded information, or his life. He refused, so Fingol followed through on the threat and blasted him with lightning.


Fingol attempted to harvest ectoplasm from the men, but they were not truly ghosts. They carried a decent sum of coin and gems, as well as two potions and a mysterious dust.

The Hypogean Oracle Review Post-Mortem

  The judging period for the Adventure Site Contest III is officially over, so it’s time for a post-mortem on my entry, The Hypogean Oracle....
