And thank you for what you’re doing. It’s a great extension.

Oops :D

Thanks for letting me know! I'll fix it in the update coming out soon.

Hello,

I am trying to configure a power that uses a melee attack roll. Unfortunately, I get the following error:

[1/18/2026 3:39:49 PM] [ERROR] Handler error: [string "..ons and House Rules:..agerActorAdvOpt.lua"]:222: attempt to call global 'getAbilityBonus' (a nil value)

I also do not get any message in the chat for an attack roll, even when changing the settings (Ability, Fixed, nothing).

I get the same error if I try to make an attack roll from the Main tab using THAC0 or with a weapon on Action tab.

Sorry about that. I've released a new version that should fix that and address a few other things. If you continue to have issues with the power creation, let me know. I did my best to do the same thing I think you were doing, but not 100% sure. Thanks for the testing and report!

Thanks. Everything seems to be back in order. I have a session tonight to verify.

Made some changes to account for changes in Core and 2E. If anyone sees anything not working, please let me know. Thanks to the individual who reported the issues that this update hopefully fixes for now.

Hi, I am looking to run a 1e AD&D campaign in the near future for some friends and I was planning on using your AD&D options and House Rules extension to do just that. If I wanted to stay as close to Vanilla AD&D as possible would it be better to run it with your OSRIC Ruleset, the 2e Ruleset, or does it not make a difference? I'm sorry if this has already been asked, I looked through the old forum posts but could not find an answer.

I'm trying to run AD&D as I remember it with a group that hadn't played AD&D before, for me using the 2E rules and Doomsword's extension it has the feel. Doesn't quite map (clerical domains and changes to some spells and levels and the like) but by turning off some of the 2E options it's close.

Sorry for not responding sooner.

The most important thing is to decide which rulebooks you want to use if you're not making your own. The paid 2E materials are well-made and will work fine, but there are many things in those that are very much different from their 1E counterparts. If you're fine with that, that will work fine for you. On the other hand, the free OSRIC materials available from the Forge, here, work very well also, and will get you much closer to 1E

After that, it's a matter of deciding whether you want to use the OSRIC ruleset or the 2E ruleset. If you use the OSRIC ruleset, you'll likely want to use the extension, as it gives you much more control over making things more 1E-like. Same goes for the 2E ruleset. The OSRIC ruleset itself was built on the back of 2E, and was designed to eliminate the things in 2E that aren't used in OSRIC/1E. It's a simplified ruleset (and it needs a couple of updates which I can hopefully get to soon), but it's a good start and will do extra things like try to convert the monsters in paid Classic adventures to their OSRIC counterparts. It's really just a matter of preference. Do note that the variations from 2E present in the OSRIC ruleset don't otherwise change the reference materials, and you'll need to make some changes to those books if you want everything to match.

I've been meaning to put together some functionality examples via video, but haven't gotten around to it.

If it were me, I'd try some or all of the above and see what you like best. If you have any other questions, just let me know.

New update is live. It brings a number of improvements to the experience, fixes several option issues, does a better job of automating effects (especially related to death and dying), and hopefully makes all of the PC Death options work properly. There is a lot of redesign under the hood, too, so I would definitely make sure to test out your basic workflow and make sure your options are set the way you like them before you run a game. I don't anticipate problems, but I can't test everything everyone does. I did my best to make sure it works well, though. If you find any issues, please let me know.

Update to fix error message when dropping encounter on ct. Thanks to the individual who reported it!
