rulings: magic item creation & earned resistances


Magic item creation


Here's a first stab at my magic item creation rules. This was inspired by someone else's idea on /r/osr I think, and adapted to Knave. In practice using this idea has been pretty spontaneous in play, and happened thrice now over the course of around ~18 sessions. So not hugely common. Also, it's only been weapons so far, which perhaps speaks to the style of my game, but I'd like to lean into this idea further for armour, lanterns, rope — perhaps even the party's mule, Clem.


The basic setup is magic items can't be crafted, per se, and certainly not purchased reliably. They're created in the heat of the moment, during an adventure.


Weapons


When a PC strikes a powerful blow that slays a creature — think crits on the killing blow, or juuuust manages on the to-hit but still rolls max damage, that type of thing — the weapon may be imbued with magical force. Mechanically, their formerly mundane weapon gains a +1 echantment and counts as magical, but it also gets a +3 enchantment against the specific creature type that birthed it in the first place.


For predatory creatures usually encountered alone, this may be after killing a single one. For creatures that travel in packs, are docile, etc, this may be after having established a pattern of killing them before the critical blow is landed.


Eg: Shyan having beaten several goblins in combat, lays another dead with a critical strike. She finds her blade suddenly imbued with magic, then and there. It's now a +1 blade, with +3 against goblins.


Armour


If a PC would have suffered a killing blow were it not for a piece of armour, it can be imbued with resistance to that particular creature's attacks. Mechanically this would mean suffering no harm from damage rolls in the bottom half of the bracket, ie, 1-3 on a 1d6.


If the PC has a shield and is missed by 1 (the defense value of the shield) then it's the shield that becomes magical, not the body armour. Not sure how to handle helmets, which, in Knave, also provide 1 defense.


Eg: Fassn has a defense of 12, as he's unarmoured save for a shield. He's attacked by a glob of poison from a trashcrab, but it rolls a 12 to hit, so Fassn is protected, thanks to the shield. The trashcrab's damage roll was enough to have killed him, and he feels magic suffuse the shield. It's now +1 defense (bringing its total as shield to +2) with +3 against trashcrab poison.


Admittedly this one would be more fiddly, and I'm not sure PCs want to track a floating defense score varying by creature type. I might instead rule the shield is a +1 and resists poison, leaving the specifics up to the table.


Healing items


This is something I've done in the game as well. PCs were getting paralyzed by ghoul touches and didn't have a clear way to cure this. Thanks to random character generation, one of the PCs had flowers in his inventory. Mundane, as far as we could tell. But he opted to use them as smelling salts for a paralyzed friend, and since he'd already beaten the touch himself thanks to a good save, I ruled that he could allow his paralyzed friend a fresh save himself, with advantage. Sure enough, the flower helped his friend, and we discovered its properties in the fiction.


Magical resistances


Something else we've seen at the table is a growing resistance to certain toxins. As above, the party encountered several ghouls, and many came in contact with a paralyzing touch. I ruled that once you had beaten the paralyzation sucessfully, your antibodies learn about it, and so future saves can be made with advantage. You can effectively develop resistances from exposure.


This has the effect of making the game easier, and more surviveable for low level PCs, but it also keeps the wheels turning in combat and helps not to bog down in, in this case, multiple PCs being paralyzed for several rounds. While that can be exciting, it can also be a drag, so this is a way to slowly guard against that.


A downside is a PC should maybe track the creatures they've grown resistant too, 'cause I as the ref don't want to. Maybe if I have them make a standard save somwhere down the line someone will pipe up and ask for advantage, due to previous exposure I'd forgotten about. If so, great! They're engaged and contributing to the game. If not, well, meet or beat a 16 I guess...




Surely there's more to say on this topic, and I'll continue to expand and refine my thinking as we play. What are your thoughts? How do you handle magic items? What would you love to see tried sometime at the table? Share your ideas in the comments.

session summary: knaves of the earth, 200223

Following their intuition and the cool chill coming from above, the party returned to the buried pyramid's torture chamber and tore aside the vertical stretching rank and wich. In doing so, Luwang was buffeted by a forceful blast, the bellowing screech of High Priest Vladdis. The wraith bore an icy longsword and an amulet and charged for Luwang, but failed to injure the skeleton. As Luwang swung his silver greatsword, Mirabilis, sensing the amulet's importance, sprung to the sarcophagus to deface it wih his file. Doing so caught Vladdis' attention, so Ferris sprung in to divert it. Unfortunately, the vandalism was too strong a lure, and Vladdis grazed Mirabilis's helmet, sending a cold, coursing shock through the former thief's body, leaving him stunned. Ferris plunged his icy touch into the spectre's ethereal form, and with an outpouring of willful magic, froze the wraith completely, letting it shatter upon the sandstone floor. Attempting to shake off t...

The Hess' nest stinks of rotting fish. Our Hess partner introduces himself as Jez, along with his friends, rotund Gruzz, who bears a third eye, SaSo, and Nant, whose scales lack all pigment. We discuss the Hess' missing idol until wormlings assault our position from all sides. We take one out with a bear trap, and do our best to spike the doors closed, but a brawl breaks out. Alongside the Hess, we slaughter and loot them all. Umesh scouts our surroundings, finding a pile of "fake dead," before Gruzz reveals a secret door in their lair, filled with loot. With the Hess, we head to the wormlings' hideout and sack it, too. The Hess tell us of their twisted cousins, the Yoch Hounds, and we encounter old writing under algal growth, telling us to "pray before the benediction of Kezek; the blessed may pass the fall and come to the deep." Kezek, we learn, is the Hess' idol. Shortly thereafter, we reach a massive lizard carving with outstretched hands, surrou...

Yama, Ade, Qui, Bishal, Umesh, w/ tipsta as ref Jade's Favour has been making money and moves in the world; found a new home for a dragon, uncovered the secrets of the sky metal, funded an insurgent group in the Roach Feeders. Now we're on a quest to recover the world's most powerful magic word: Reincarnate. We seek the watchtower in the Topaz Isles. With the help of Spider Climb, Yama reaches the top, spying on the way a family of spiderpedes, as well as some conspicuously tidy rooms. At the summit, he finds four platonic solids of pure sky stone, and vaults them down for the gang to recover. In his descent, Yama encounters a brilliant gold and red elemental lion — the Sakomere Guardian — while the gang below is set upon by a clutch of grim natives bearing spears. Yama pleas his case, and the lion agrees to show the way to the Grand Palm in exchange for the solids' return. The lion and its followers depart as Yama is killed by a spring trap of spiders, so the gang foll...
