As a way of procrastinating from doing more work on the adventure-campaign book I've been working on seemingly forever I decided to collect my miscellaneous "OSRIC" house rules and additions that weren't included in The Heroic Legendarium, either because I only came up with them after the contents of that book had been finalized or because for whatever reason I forgot to include them there. A lot of this stuff is pretty simple and minor, to the point that it didn't necessarily need to be formalized in writing, but a couple of them are more substantial and impactful.
While I'm not so naive as to believe anyone besides me would want to actually use all of these rules and rulings in their games (surely anyone running a 1st edition game at this point has already resolved all of these issues to their satisfaction many years ago), maybe some folks will find something they like here, and - as always - I've already done the work of writing it all up so why not share it, right? So, that said:
Update: In a fit of inspiration, I decided to combine this document with the other house rules and play aids I've published here over the last couple years (since the HL text was finalized) into a smallish (20 page) pdf and put it up on DriveThruRPG as PWYW. I'm still a second-class citizen there so it hasn't gone live yet, but should within the next couple days (and when it does I'll probably make another post about it with a link). The Necropolis conversion notes aren't included (both because they're incomplete and because I'm not sure it would actually be legal to upload them for sale there - I know people sell 5E conversion guides for old 1E modules but am not sure what the rules are for that and don't want to take any chances and risk a repeat of last year's Lulu fiasco) but everything else is. Most of you reading this have probably already downloaded anything that you're interested in, but it might still be convenient to have it all in a single file, plus it will at least theoretically reach the people who (shockingly!) don't read this blog.
