Network System Success Rates

The following table summarises the chances of success (in percentages) for various Target Numbers in the Network System (used by Sertorius, Servants of Gaius, Terror Network, and Wandering Heroes of Ogre Gate (all affiliate links)). The resolution mechanic is "compare highest result of Nd10" (except for 0d10, where the result is the lowest of 2d10). I have included probabilities only up to 6d10 as it is a soft cap in Ogre Gate.


0d10 1d10 2d10 3d10 4d10 5d10 6d10

Review: Engines & Empires

This review is part of a series on thematic OSR games (as defined here). Also note that some of the links below are affiliate links (meaning I get a small percentage of the sale without extra cost to you).

Engines & Empires is an old-school steampunk fantasy game. It has seen multiple iterations over the years (the first version saw the light of day in 2008, I think). This review concerns itself only about the most recent edition released in 2017.

XP for Exploration in Hyperborea

This is a fairly lazy post about adapting Jeff's eXPloration idea to Hyperborea. I'm a little behind with finishing my reviews due to editing a fantastic (and quite gigantic) book. Nevertheless, I'll try my best to squeeze one in before the end of the month.

In this variation of advancement, XP is awarded solely for visiting major cities, studying the Great Obelisks, and finding hidden wonders. The XP awards aren't divided among party members, and each character can earn XP for visiting a given location only once. I would probably use my own set of hexcrawl procedures to run such a thing.

Visiting any one of the twelve great cities of Hyperborea is worth 2000 XP. The great cities are the following:

  • City-State of Kor (Fields of Vol)
  • City in the Clouds (Floating Island of Paradoxon)
  • Gal City (Gal Hills)
  • Krimmea (Kimmerian Steppe)
  • City-State of Khromarium (Lug Wasteland)
  • Pandoros (New Amazonia)
  • Fidib (New Pictland)
  • Fazzuum (Scythium)
  • City-State of Orcust (Skarag Coast)
  • Erikssgard (Vikland)
  • City-State of Yithorium (Zakath Desert)
  • Port Zangerios (Zangerios Islands)

Studying any one of the Great Obelisks for a week is worth 5000 XP.

Lastly, every region has 4-6 hidden wonders. Finding them earns the characters a progressively larger XP reward within a region (that is, finding two wonders in two separate regions nets 200-200 each, while finding two in the same earns 200+500). The rewards are as follows:

  1. 200
  2. 500
  3. 900
  4. 1400
  5. 2000
  6. 2600

For instance, the Gal Hills might have the following hidden wonders:

  • the burial mound of King Arlan the Wolf
  • the sacred grove of the blackthorn druids
  • the spring of beauty
  • the menhirs of the elements
  • the pool of visions
  • the slumbering evertree

Lessons Learnt Running Megadungeons

Disclaimer: Some of the links below are affiliate links (meaning I get a small percentage of sales without extra cost to you).

I have been running megadungeon products a lot. I've run Barrowmaze (the first volume) for two regular players in person, I am still technically running Dwimmermount for a face-to-face group (although we only played like 3 sessions each year, and none so far this year), plus I am actively running Rappan Athuk online (we spent about 20 sessions down there, but the campaign is on the cusp of turning into something very different).

I have tried to summarise my thoughts about running megadungeons, focussing on some of the issues that I have. I must add that I immensely enjoy reading and running megadungeons, so these concerns aren't about invalidating the concept but rather things that if solved would make it an even better, smoother, and more rewarding experience. I should also add that these issues may come up in other types of adventures as well; they just seem exacerbated in megadungeons.

TL;DR: (1) consider the costs and benefits of grids and gridless dungeons; (2) add environmental cues around branching off points on the map; (3) use observable warning details around traps consistently; (4) secrets doors should always be interesting; (5) random encounters should have details that you can build on

Current AS&SH House Rules

Attribute Generation
Roll 3d6 in order to generate your first array. Your second array is the inverse of this (18 and 3, 17 and 4, 16 and 5, etc.). Choose whichever array you want. Make sure you qualify for the class you want to play.

This house rule is taken from Esoteric Enterprises (aff link), and it's supposed to provide a nice middle ground between 3d6 in order, 4d6 drop lowest, and 3d6 arrange to taste. I personally haven't tested it; I just assume Cavegirl did.

Hit Points per Level
Upon attaining a new level, either roll a single HD (plus CON modifier) and add the resulting amount to your total HP, or reroll all your HD (and CON modifier times your new level) to determine your new HP total. If the reroll would result in no increase in HP, increase your total HP by 1 instead.

This is a house rule I have been using for years now. It has worked fine so far. The intent is to alleviate the impact of really bad hit point rolls in the long run.

Scroll Use
Spellcasters can identify scrolls of any tradition. They can also use scrolls of any spell level. When they use a scroll of a different tradition, there is a 2-in-6 chance of miscasting (1 random target, 2 half efficacy, 3 half duration, 4 lose 1d4 random ability points, 5 opposite effect, 6 different spell of same level).

This one's a bit trickier. I haven't actually tested it at all. Since AS&SH uses so many different spell schools, the scrolls in most OSR modules would need to be tweaked, otherwise only Magicians and Clerics would have a chance to find usable scrolls (let alone learn new spells). This house rule is basically my lazy way of handling that instead of rerolling every scroll found on the fly using the tables in the rulebook, while also helping out casters in situations where I actually do roll on those tables.

Encumbrance
Encumbrance limits are calculated based on one’s Constitution score.

This one we haven't tested yet, although The Nighmares Underneath (aff link) already does this. It makes more sense in the fiction (because encumbrance isn't really about raw strength but endurance, plus STR already has so much going on for it.

Critical Hits
If an attack roll is a natural 20, use the standard critical hit table in the rulebook. Furthermore, critical hits add a notch on the target’s armour (or shield, if they so choose).

Critical Misses
If an attack roll is a natural 1, the attacker chooses among the following options:
1) Weapon gets a notch (-1 to-hit and damage per notch; breaks at 3 notches)
2) Attacker is disarmed (weapons falls 2d6 feet away in a random direction)
3) Attacker gets off-balance (-2 AC penalty for 1 round)
Unarmed attacks always result in off-balance, while ranged attacks always result in a notch.

Weapon notches have been part of my game for a really long time (about 30 sessions, probably more), and they have proven to be a very nice addition. The intention is threefold: (1) to incentivise bringing more weapons along, while balancing encumbrance; (2) to surprise the GM and the players at the table at times; (3) and to provide another resource to juggle, one which is decoupled from levelling. Repairing weapons costs one-third of its gold value per notch, which is especially expensive for magical weapons (although they are able to withstand more notches in general). High quality weapons are easy to model in mechanical terms without introduction to-hit and damage bonuses, too. It also generates anecdotes, like the fight with a bunch of skeletons, where the party suffered like 10 notches and had to retreat immediately, even though they had plenty of HP and spells. Even trivial fights may deplete precious resources now, which is a huge positive for me. As for the other options, I have tried similar outcomes in the past, but this is the first iteration I find actually fitting. This way every attack has a possible negative outcome, but there is also player choice involved for most cases.

City of Masks - First Peek

Here is a little preview of something I have been working on: a city supplement presented as a random encounter table. Below you can find a work-in-progress description of a district, plus a piece of the encounter table expanded.

Review: Songbirds

Note that some of the links below are affiliate links (meaning I get a small percentage of the sale without extra cost to you).

Songbirds is a fantasy game based on the system of Into the Odd, albeit with a lot of changes. It mixes the simplicity and adventure game core of its parent game, and then mixes it with indie narrative concepts. It is similar to Whitehack in that regard.
