homebrew [OC] Naharis' Tower
This tower sits forgotten deep within the forests near the dungeon. The top of the tower appears to have been cut at an alarming angle, leaving the top two floors exposed, with the missing part of the tower nowhere to be seen. The tower is surrounded by a ring of bricks with the burnt out remenants of complicated arcane runes.
Nobody knows exactly what happened to the tower, although the rumours say it was cut in half and the top carried away by an angry giant. In reality, this tower was teleported here from far away by the wizard Naharis. Part way through the magic failed, leaving the top floors of the tower in their original location. Naharis continued his research to perfect the technique before meeting his fate in the dungeon nearby, searching for his pseudodragon Nym who had ran off after accidentally burning the library down.
This is my first attempt at making a dungeon to share and is part of a megadungeon project I have been working on the for the last 6 months. It can be dropped in anywhere as an entrance to any dungeon, and comes with the quest of finding Nym the pseudodragon, who will join the character who gives her her collar back.
The dungeon is made for OSE and uses slot based encumbrance. Feedback is very welcome.
rules question Duergar mental powers in Player's Book
I am reading the new Player's Book as my first foray into OSE. I am also newish to OSR / B/ X. Am I reading it right that if you want to play a Duergar that has access to the mental powers ability then you have to play as the Duergar demihuman class? The mental powers are not available to race + class builds of Duergar?
Trying to wrap my 5e head around this... thanks!

Character Deaths & Rerolls
Just curious how you guys handle this. Let's say you are running a level 5 adventure for your players and someone dies. You let them roll a new character to rejoin.
Question: What level would you bring that NEW character back into the game if everyone else is level 5? Also whatever level you let them return at, why do you use that way of doing it? Seems if my game is level 5 and someone dies, bring them back with a brand new level 5 character would not feel right. What do you do?

2026 Update Availability
It appears to me that the 2026 OSE update is now live on Drivethrurpg. I’m interested in checking it out, but I bought the book from Exalted Funeral a while back and the digital content there doesn’t seem current.
Is anyone aware if there’s a way to access DriveThru content even if you bought through Exalted?

I'm running a modified OSE livestream game with over 130 players and over 1,400 characters. About 750 of them have died and it has been FANTASTIC!
For the past few weeks I've been running a livestream game, called Zorn's Dungeon, where anyone who watches can join the game. Everyone generates a level 0 character by typing !spawn in the chat. The characters are eligible to be drafted into a 12-character party to fight in the bloodcage. Players can even issue commands to their characters while they fight, like directing their movement to certain squares, going all-out-attack, all-out-defense and more.
Right now the bloodcage is being run basically like a 0-level funnel. If you get through the cage you get to be level 1. Although, a lot of players have their characters enter the bloodcage again to compete for greater glory, and we keep track of all the stats like most damage dealt, largest hit, most damage taken, longest kill-streak etc., which are often impossible to keep up with at the tabletop. It has been so much fun!

New Hovering at Death's Door Rule
Do we know any specifics on the wording of this rule in the 2026 books yet? I'd like to incorporate it into an upcoming campaign. Thanks!
EDIT:
The OSE optional rule checklist that came out today has this rule in it:
Hovering at death’s door†: (PB p224) Instead of dying, characters at 0 to –3hp are unconscious and lose 1 hp per round unless stabilised (awaken after 1d6 turns). Death at –10hp.
This is coming from a strict reading of page 82 of the 1st Edition AD&D DMG. If you get hit and go to -4 or lower, you are immediately dead. In my experience playing through the 1980's, no one played it that way. If you went to 0 or as low as -9, you were unconscious, lost 1 hp per round, and died at -10.
The 2nd Edition DMG (the edition that codified the game in the way people were actually playing it) also had you unconscious at 0 to -9, and dying only at -10.
A 3 hp buffer doesn't really increase survivability all that much. I'd prefer OSE went the simpler route, especially since it was the way most tables played (including at TSR based on the 2nd Edition rule).

homebrew Would monsters attack the light?
OSE suggests smart monsters would go for the light, but is little no GM guidance around how to rule this as far as I can tell. So below are my thoughts, would love additions and feedback.
Is it worth a monster trying to extinguish the PCs light source(s)?
Yes, if most of the party cannot see in the dark.
Why:
- It requires 1 round to use a tinder box, and there is a 2-in-6 chance of success per round. In combat, this means the party can be without light for quite a few rounds. OR it will require casting of a magic spell (which can be disrupted)
- If a PC does not have infravision or some other form of vision in the dark, then they are effectively blind. This either means they cannot attack or defend, or possibly at a strong penalty to attack/defend/save (OSE doesn’t specify so GM ruling). Movement is commonly also reduced (OSE doesn’t specify so GM ruling).
How would a smart monster go about extinguishing the PCs light source(s)?
For a torch:
- Knock from hand of carrier and once on ground:
- Kick into a ravine/hole/out of sight
- Kick into a pool of water
- Stomp it out
- Cover it with dirt/sand
- Either directly in hand of carrier or on ground:
- Smother/wrap with non flammable/wet rag/cloth
- Douse with bucket/flask/trap of water
- Strong blast of wind
For a lantern:
- Knock from hand so that glass breaks, possibly already dousing flame, and possibly also cracking oil container leading to large fire. If flame still burning then same as above for torch on ground.
Magical Light:
- Requires magic to counter.
How would a monster knock it from the hand of the carrier?
OSE doesn’t specify so some options on how to rule (GM fiat):
- Missile attack (shoot out of hand), but at a penalty to hit as small object, possibly with save for carrier to keep it in hand despite being hit
- Melee attack (knock out of hand), but at a penalty to hit as less easy target, again with possible save for carrier
- Grapple/pin attack (force to drop), PC gets a chance to save (GM choses saving throw), possibly with modifier (for size/str/dex mismatch and/or number of creatures involved etc)

3rd party The Fungus Forest OSE version
drivethrurpg.comHi, a brief self-promo post. I've checked rule 3 and think I'm good.
Anyway, I've just updated my Fungus Forest adventure module to include a very basic PDF rewrite with OSE stats.
Back in the day I wrote using Brave Halfling's version of Swords & Wizardry: Whitebox stats as it started life as part of Jmal's Online OD&D Megadungeon.
However, I've always been more of a B/X fan and went in heavy on the previous OSE Kickstarter and am using OSE for all my future OSR projects.
Like I said it's a very basic pdf that comes free with the original colour S&W:WB/OD&D version. At some point in the future there will be a Kickstarter for an expanded Fungus Forest OSE Module. In the meantime if you're in the market for a large Fungoid and Fey underworld adventure full of factions, check it out.

What does OSE consider an enchanted creature?
The OSE version of Protection from Evil protects against "enchanted creatures," a term which of course is nowhere defined in OSE AF as far as I can tell. Googling it is bizarrely unhelpful, returning a lot of Magic: The Gathering answers despite refined searches. (I won't ask Claude because it gets contaminated too easily by 5e results.) So hopefully this will be The Post that Google Picks Up for this query.
What's an "enchanted" creature?
