This is a partial list, since the revisions are still in process: 1. Option for Ascending Armor Class. The OSRIC default system for AC will remain descending, but there will be a section explaining how to use Ascending AC, and all AC notations will be "dual-system" like in Swords & Wizardry. For example, AC 4 will show up in OSRIC 3.0 as "AC 4 [16]." We have found through Swords & Wizardry that this dual notation isn't intrusive. 2. Adding Encounter Distance to the combat sequence, per AD&D rules. Not precisely the same method -- the AD&D rules for encounter distance and especially how they interact with surprise are at wargame-level complexity, when they really don't need to be. But encounter distance has been a missing element in OSRIC, so the basic concept is now in there. 3. Adding a Monk class. Numerically very close to the original, but with certain abilities dependent on meeting the stat minimum. 4. Initiative Sequence. The changes here are mostly nuanced, but we are bringing the system closer to the AD&D method of declaring your action at the start. The one "major" change is that you roll your own side's initiative (1d6, and you go in the stated segment) instead of rolling a die for the "other" side. 5. Item Saving Throws. This is the first area where we are backing away from the AD&D rules more than in OSRIC 2, due to licensing/legal under the CC as opposed to the OGL. We have trimmed down the number of materials affected, and slightly trimmed down the number of categories. It's now a quicker table to use, which is actually probably preferable for what it's used FOR (fireballs, disintegration), but it does mask some of the high detail of the original (no distinction between thick and thin rope, and so on). Material categories are Crystal/Glass, Leather, Metal, Paper, Pottery or Bone, Rope or cloth, Stone or gem, and Wood. Threat categories are Acid/Corrosion, Cold (Magical), Disintegrate, Fall (each 10ft), Fire (Magical), Fire (Normal), and Lightning. 6. Gnomes and halfing multiclass characters are limited to leather armor if using a character ability from a non-fighter class (e.g., casting spells or using thief abilities), not always limited to leather armor only. This brings the rule into line with 1e. 7. Slight changes to the fighter and the illusionist XP tables to bring them closer in line with AD&D. 8. Adding the DMG rules for druids, clerics, etc. to scribe scrolls and brew potions into the OSRIC class description (in other words, this is new to OSRIC but brings it in line with AD&D). 9. Changed the high level thief's spell casting from scroll to match AD&D more closely. 10. Returning the saving throw bonus for Dex on aimed magic items, AoE spells and other "GM says this is a Dex-type save" situations. This brings the rules closer in line with AD&D (was not included in OSRIC 2.0).

All physical book pledges receive PDFs of the books purchased in that pledge (in all layouts, even if the pledge was for a specific layout) and the Reference PDFs are included with all physical book purchases. So the "Player Guide only" physical book pledge does not receive PDFs of the GM Guide, but does receive PDFs of the Player Guide and the Handy Reference PDFs (which are basically from the Player Guide). All other physical book pledges (containing both rulebooks) receive all the layout options in PDF form and also receive the Handy Reference PDFs.

BackerKit Crowdfunding is an all-or-nothing collaborative funding platform. Creators share their project ideas and set a funding goal with a deadline. Backers pledge money to help make the project possible.

If the project meets its goal by the deadline, pledges are charged and the creator moves forward. If it doesn’t, no one is charged.

Pledging in crowdfunding is a commitment to support the creation of a new product or project. Unlike a traditional purchase, you're not buying an item that already exists. Instead, your contribution helps bring a creative idea to life, and in return, you typically receive rewards (such as the product itself) as a thank you for your early support.

1. Select a pledge level with the reward(s) you would like to receive
2. Select any add-ons
3. Confirm your pledge!

• You are charged only if the campaign meets its funding goal.
• Charges happen when the campaign ends, not when you pledge.

After the campaign ends, you'll receive a survey to pay for any applicable shipping fees, calculated based on your shipping address.

Pay Over Time allows you to split your pledge into multiple payments over a set period. Your card will be charged according to the payment schedule (four monthly payments). Only available for projects that enable this feature. Learn More »

Only the project creator and the BackerKit Support Team can see your pledge and contact information. Other backers and the public cannot see your individual pledge amount or personal details.

You can change or adjust your pledge level and add-ons before the campaign ends. After the project concludes, cancellations or changes are at the creator's discretion and may depend on what stage the project is in.

Overtime Mode extends your campaign past its original end time to give backers a final chance to make their pledge. It will add an additional 10 minutes past the end time as long as pledges keep coming in. The campaign will end when there is a 10-minute period without any new pledges.

For specific questions about your pledge or the project, you can view the Project FAQ below, search for your answer within the project, or send a message to the BackerKit Support Team or to the project creator.
