Schrödinger's Backpack

Every character has a backpack or equivalent carryall.
It is assumed that your pack contains:

  • 1 week of rations
  • water skin
  • bedroll
  • change of underthings
  • Something Class-specific (equipment for maintaining weapons, spell book, holy symbol, lock picks, etc.)

All other contents are uncollapsed wave functions.

When you need something, roll against your WIS (or maybe LUCK, if you have a Luck stat) to see if you thought to pack it.

  • First item: roll 1d6. (Automatic success if WIS is 6+)
  • Second item: roll 2d6. (Automatic success if WIS is 12+)
  • Third item: roll 3d6. (Automatic success if WIS is 18)
  • Etc.


The GM may add/subtract a die to/from the roll based on how likely they think it is to be in your pack.

You may only roll once for a given item in a given adventure.

Once an item is produced from the backpack, write it down. That item is now definitely in your pack until the next adventure.

The quantum backpack resets at the end of each adventure.

Before an adventure begins, you may specify up to three items that are definitely in your backpack. To find anything else, however, you must begin rolling at 4d6.

Encumbrance
You can carry stuff until the GM calls shenanigans—usually because of extra weapons or treasure.
First shenanigans: Encumbered. All physical Attributes are effectively at -2.
Second shenanigans: Heavily encumbered. All physical Attributes are effectively at -6, and movement is dropped to Slow.

If “Shenanigans” is too imprecise, then allow each character to carry as many items as their STR. Large items (like two-handed weapons) count twice, and treasure is 100 coins per item. The backpack counts as three items by itself, not counting whatever items you have discovered in it.
Items > STR = Encumbered.
Items > 2*STR = Heavily Encumbered.

Unprepared
If a character starts out an adventure without a pack, they can roll an extra hit die. These extra hit points will last as long as the character remains substantially unequipped. However, the character will have trouble recovering hit points without rations, a comfortable place to sleep, and dry socks to change into. Instead of allowing automatic time-based healing, require checks to hunt, forage, and make camp.



Notes
Just noodlin', over here. I haven't playtested this even a little bit. Or even really thought it through all that much.

Obviously, this is not for games that are focused on resource management.

This is based on a notion +Jarrett Crader  used in his Whitehack Chargen document, which, in turn, is inspired by DungeonWorld.

This would require rethinking starting wealth. Maybe everyone but fighters start out with 3d6 cp?

Addendum
I suppose a character could choose to pack heavy instead of packing smart. Packing heavy would allow you to use either STR or CON as the attribute tested, but would take up... I dunno, six slots instead of three?

Maze Rats by Post

In my previous post, I reviewed a bunch of my favorite rulesets for optimization for Play-by-Post. It occurred to me almost immediately that I hadn't really thought about Maze Rats enough.

In fact, I'd mis-remembered and mischaracterized it. Upon reflection, one of the mechanics I took issue with is actually a big strength. Re-reading the rules, it seems like just a few very simple hacks could make it a highly-optimized PbP game.

As follows:
Danger Rolls are rolled by the GM.

Danger rolls usually fail, so it is in the player’s interest to describe their actions plausibly and mitigate as many risks as they can, in the hopes that they don’t trigger a danger roll.

2d6 + ability bonus ≥ 10

If you have taken enough precautions to have a distinct advantage in an action, but not enough to have eliminated the distinct possibility of danger, the GM will give you a roll with advantage.

3d6 keep 2 + ability bonus ≥ 10

Because each character only has 3 ability scores (STR, DEX, WIL), it s…

Reviewing Rules for Play-by-Post Optimization

I’ve played a lot of PbP games: all your favorite flavors of OD&D, AD&D, and their retroclones, Call of Cthulhu, Marvel Superheroes, Traveller, Dungeon World, etc. ad nauseam.

In almost every instance, I forgot what ruleset we were using at some point. Which is a good thing. Once chargen is over, you spend a lot more time describing your characters actions and poring over the GM’s descriptions than you spend interacting with rules. When you do roll, it’s usually a combat to-hit roll, which you’ve probably programmed into the online dice-roller as a macro. Pretty much any game will work for PbP.

But that doesn’t mean there aren’t points of possible optimization.



Point 1: Resolution. Anything that can keep the action moving is a boon to PbP. A game that requires a back-and-forth exchange of information to resolve an action is going to progress very slowly. A good rule of thumb is that it’ll take 2 or 3 days to get a response from any given player. At that pace, an exchange that w…

Knaves, fancypants

I've prepared a new layout document of Ben Milton's Knaves.

Knaves is a great, light rules set that has an extremely elegant core mechanic while retaining total compatibility with OSR material. It's pretty much the rpg of my dreams.

This document contains the complete rules, plus a bunch of useful hacks from the community, plus a few of my invention, plus some useful resources from Ben Milton's previous effort, Maze Rats.

Here's a link to the pdf:

KNAVES LAYOUT


This is presented with generous permission from Ben Milton, and should in no way be an excuse for not purchasing a copy of Knave from Drive-Thru RPG. It's inexpensive, and deserves your support. Also, Ben's layout is 100% the one you're going to want to print out for reference at the table.

Let me know if you see any mistakes or areas for improvement!
