    OSRIC conversion for 2E

    It turns out that legally sharing our homemade adventure modules with each other is difficult if it relies on licensed 2E content (such as PHB spells, MM monsters, etc), so for the purely selfish reasons of hoping I end up seeing some homemade modules posted that I can then shamelessly steal and use in my game, I've decided to convert OSRIC for the 2E ruleset. Note that this is meant to be played in 2E... it's not a separate "OSRIC" ruleset. I have seen that there was some other OSRIC content community mods in the past, but I think they were meant to be used with an OSRIC extension that changes how the 2E ruleset plays. This is not meant to change any of the rules of the 2e ruleset or how the game plays... it's just a different set of data than what you'd get from the 2E Player's Handbook or Monstrous Manual.

    Work in Progress

    So far, I've converted all of the races, classes, weapons, armor, and spells from the OSRIC core rules into a module, and am currently working on monsters. I plan to grab the monsters from both the core OSRIC book as well as Monsters of Myth. I currently don't plan to convert any magic items.

    This is all free for anyone to use, obviously. It follows the same license as OSRIC, and I'm not a lawyer, but I think that basically means you can use it in your published content (free or even for money) so long as you include the license and attribution. If you're going to sell any content you make using spells/monsters/etc from this, though, don't trust my word for it... look into that yourself.

    Once this is done, since I'm a little crazy, I plan to tackle a For Gold and Glory conversion too. That one more closely matches 2E's rules and would be a better fit for the ruleset, but a lot of modules I'm converting on a personal basis come from OSRIC content, so I wanted to start there first.

    I will post updates to this thread as I complete the NPCs from the core OSRIC book and then the Monsters of Myth book. I plan to have the NPCs use the 2E Thac0 table for monsters rather than the OSRIC Thac0 tables, but otherwise their stats and abilities are going to match what's in the OSRIC books. I'm undecided if I'll use the 2E DMG's guidelines for determining XP for a monster, or if I'll enter whatever value OSRIC would have based on the creature's average hit points (since in OSRIC, XP often looks something like 75xp + 2xp/hp). I'm open to suggestions there, but I'm leaning towards 2E, with an eyeball towards how For Gold and Glory handled XP values for similar monsters (which, of course, in practice really means how the Monstrous Manual handled XP for similar monsters).

    I've tried to add effects where appropriate to spells, classes, and races, but I have not playtested much of this. Please let me know if you use it and find problems. In particular, let me know if you see problems with spells with Auras, which are a new effect type I don't have much experience with. In some cases I just used the aura as a visual indicator but you still have to add the desired spell effects "manually" to who you want.

    One final note... OSRIC handles spellcasting a little different than 2E. Druids have a separate spell list, as do illusionists, and there are no spell "spheres" for clerics. There were quite a few spells that would have been of the same type (Arcane or Divine), maybe even the same level, but been slightly different depending on if it was for an illusionist, a magic user, a druid, or a cleric. Since the 2E ruleset code for determining spell level for effects only supports "Divine" and "Arcane" magic, I handled it as follows:

    Cleric spells are "Divine" and have an empty sphere attribute.
    Magic User spells are "Arcane" and have an empty sphere attribute.
    Druid spells are "Divine" and have "Druidic" as their sphere.
    Illusionist spells are "Arcane" and have "Phantasmal" as their sphere.

    Please let me know if you have any feedback or see things to correct, or want to help out (such as converting magic items).

    This is a monumental task. After doing the PHB/DMG/MM I know just how much work it is. Thanks for taking it on!

    This could legally be used to convert OSRIC adventures (like the Advanced Adventures) for FG.

    One more note... I'm also developing an extension that adds various bits of extra automation and house rules to the 2E ruleset. You might see some text in the "properties" field on armor or weapons that make no sense to you. That's because they're for use by my extension. If you aren't using the extension, they'll have no impact on your game.

    I want to help out as long it does not involve too much effect coding...cause i just don t get it...unfortunately. Happy to do the donkey work though.

    BTW Can someone make a program/mod/ext/whatever with drop down menu for making effects that i just need to copy paste or even better a magical item/spell creator with built in effect coding? pretty please...

    That only had 5 classes, no items, no spells, and no NPCs. This is meant to cover everything (though I'm still working on the NPCs). It also said it was for use with the 1E extension, so I wasn't sure if that would have an effect on the way the data was input (my guess is, for the classes, it doesn't matter).

    The end goal here is to give a DM everything they need for content that can then be shared (because of the licensing differences between OSRIC and 2E) or sold.

    This started because I had started converting some Advanced Adventures on my own for use in 2E. Then I heard that FG had the rights to sell some of those, but the sold conversions can't contain any links to the 2E PHB or MM data. I personally am not looking to sell any of those modules, but this might help those who do want to convert and sell them. It also bugged me that if I made a cool adventure, I couldn't actually share it with the community if it contained Monstrous Manual NPCs or PHB spells and items. This gets around that (though the For Gold and Glory conversion will be an even better fit for that case, as it's basically reskinned AD&D 2e, whereas OSRIC is more like AD&D 1e reskinned).

    And, eventually, I plan to convert The Halls of of Arden Vul for my own use, and this is a necessary first step for that.

    monsters spells and items are in post 2 https://www.fantasygrounds.com/forum...D-Core-Ruleset the remaining classes in post 1

    that said the first bunch of classes are done very basically in the pre official days of the rule set but the monster mod is useful source for all those monsters that got dropped from 2e. I'm not even sure the first edition extension even works anymore

    Nice! I just took a look and there was a lot there! I haven't gone over it in a ton of detail but it looked like a lot of spell effects, damage buttons, and monster effects were missing though. Dragons seem to be missing powers like their breath weapons, etc.

    I'm a big fan of automation so definitely want that.

    I'm not sure whether the best path forward is to somehow merge these efforts or just keep them separate. What are you feelings about it, Hawkwind?

    Having all the effects tied to spells, powers, npcs and items will be instrumental in giving it the automation that is currently in the 2E content.
