Musings on Weapon-as-Initative

I've been trying to keep my posts pretty structured, tho this one may ramble a little.

After an exchange with Miranda of In Places Deep over on Bluesky, I started thinking about weapon-as-initiative, and it quickly reached the point where I realized I wasn't going to get anything else done until I wrote a little blog post about it.

Weapon as Initiative

From Fantastic Medieval Campaigns by Traverse Fantasy
 

The basic system: In Chainmail, weapons are given a number from 1-12, abstractly representing length. For dungeon crawling, you can use that number as an initiative score, counting down from 12 on the first round (representing the reach advantage of long weapons) and then counting up each subsequent round (representing combat getting all close and claustrophobic). I believe Tonisborg uses a system like this, tho I haven't actually read it.

The cool side effect of this is it means daggers and other small weapons basically get a double-move when the initiative flips, before the order settles back out. This sort of makes me want to try variable weapon damage, a system I don't usually use (I love my d6s).

Some Thoughts

A lot of my DMing in the last couple years has been 1-to-1, so I've mostly been using a simple side-based initiative to reduce rolling. As I'm recently getting ready to play with a full group again, I thought this would be a good time to try out a new initiative system anyway. Then it clicked for me that going by weapon type would actually be even less rolling, which I'm maybe a little silly for not noticing.

This system really appeals to me as a DM, since I could just keep a little list of players numbered by weapon type, and then slot monsters in when combat starts, and either rolling to break ties or trying some kind of simultaneous resolution.

If your gonna use the table anyway...

This is the part where I shill for Big Matrix. I've never run a game using this table but now I really want to. I like that FMC provides a target number version of the table, rather then just listing attack bonuses vs every armour tier, since that math seems quicker, at least for me. Probably in practice I'd probably keep the chart behind the screen. Not everyone at my table has experience with od&d, and I don't want to scare anyone away with a player-facing matrix.

I also like that the weapon vs. AC table could kind of take the place of varying weapon damage, making weapons like longswords scary because they hit more, but with an interesting give-and-take with their speed.

Monster-as-Weapon

Obviously monsters that can wield weapons do initiative and attacks as the weapon they're using, but what about monsters that don't? Initially, I was just thinking of giving them an initiative score, but I actually really like the idea of assigning a weapon to "fight as." It would look like this:

Red Dragon. HD 10, AC as Plate, Combat as Longsword.

The idea here being that a dragon's claws are able to shred through armour as effectively as a longsword, and that it's reach would be loosely equivalent for initiative.

I could definitely see this being transferable to other monsters. Oozes could fight as Flail, representing pseudopods which could punch around shields at weird angles. A ghoul's claws could fight as daggers.

That brings me to the end of my rambling I think! Thank you for reading :)

October Monster Roster

I really enjoy campaigns with a small selection of monsters. Luke Gearing wrote about this here . Mark Rosewater of Magic: the Gathering often says "Restrictions breed creativity." At least he used to. I haven't followed Magic in a while. That's the whole intro, I think. It's October, so I wanted to make a small list of spooky monsters, for dungeons which are creepy and/or wet. These are less new monsters and more re-imaginings of pre-existing ones. Here they are: Deathless Legion 1 Hit Die, AC as Chain. Desiccated corpses with pale grey flesh, clad in ancient armour. Very tactical and coordinated, communicating to one-another through battle-sign. Make no noise, but their armour clinks and sheds rust particles, which can give them away. Armour is either bronze rusted blue-green, or iron rusted deep orange, depending on the era of the corpse. Each legionnaire has a gold coin under it's dried, black tongue. Malice Hounds 1 Hit Die, AC as Leather. Twisted, lanky

FMC House Rules

2024/11/19: Added a ruling on HP and character death. I read it in a blog post a long time ago, but can't for the life of me remember what the post was. If anyone knows, plz lemme know! I've been flirting with the idea of starting an FMC campaign with some friends, and I wanted to compile some house rules into one place to make that a little easier, in case that does end up happening. As follows: Mortals: Prices are silver standard. Pay 1% of XP per month as living expenses. Use simple encumbrance except in edge cases. Armour prices are 25/100/1000. Any class can wear any armour. Replace Int and Wis with Arcane and Faith. Explained here. Use ascending AC. Fighters add HD to attack rolls. Everyone else progresses normally. Fighters have 1d+2 HD at 1st level, 2d+1 at 2nd. If you are reduced to 0 HP (don't bother tracking negatives), you are Injured, but can still act. Any subsequent damage will kill you. If you take massive damage equal to or greater than your maximum HP, so

od&d Witch

Image
Primary inspired by this article on thief knacks from Rise Up Comus. I'm also a huge fan of this little spellbook by Substitute Adventurer on Itch.io. I've always liked witches. Lately I've been rocking with Berserk's take on them specifically. I love the way they seem to understand what's actually going on with the world, at least more then others do. This witch is a little more chaotic though. The powers that be are fickle. This is maybe a little high complexity for od&d, but I've still chosen to go with it, since od&d is usually my preferred system.  The Witch by John William Waterhouse Class Attributes Prime Requisite: Faith (wisdom). You follow the Mother, she of the earth and the sky. You follow a loose pantheon of other gods too, when it suits you. Hit Dice and Combat Ability: As a Cleric. Equipment Restrictions: You may not wear armour or wield weapons forged with iron. Weapons purchased during character creation are made of bronze. Cool we
