Every Game Master has their fair share of custom content and home-brew incorporation. We add a mundane item here, a magic item there, pull from previous editions, or adapt from other mediums. Hell, maybe we'll change the setting altogether; flip the script and play in the whimsical alternate dimension of: Milwaukee.
Whatever the case, each Game Master has their own house rules and a whole bevy of alternative items, mechanics, and elements ready to be created, discovered, and reinforced by their players...
So I thought I'd talk about mine.
The Timeline Of Io's Seven Ages
My setting of Io enjoys seven distinct settings, or Ages, in its interwoven timeline. I did this originally to be able to offer an abundant mix of games inside the same system but with a progressive timeline. What this created was a beast of internal consistency, where the actions of a party of adventurers on Tuesday could potentially affect the world experienced on Wednesdays, and the actions of the Knight Owls could have echoes in the Gray Owls campaign. I was careful to allow a large enough passage of time to avoid any weirdness, but the extra-meta knowledge of players in multiple campaigns has been pretty cool.
What it's also done is allowed me to create a literal progression of industry from age to age, unlocking special race, class, and item options setting to setting - all of which have lore and reasoning implications. ...Like how the heck Illithids (literal Mind Flayers) became a playable race in the 6th age of Io-Firma (the Gray Owls setting). So here's a quick overview of how each Age functions and what type of setting it offers.
The NEXUS: where all creation began - the world and its gods came into being in the Nexus, where the raw energy found in its core flowed through the planet and forged the elemental forces. Many believe it still exists to this day, somewhere far beyond the planar circle yet intimately close - like a door waiting to be opened. The details of its location have been lost to antiquity, a single remnant referred to only as The Song Of The Ancients.
Io-Temm: The Worldshaping - The first age of Io, where the Seven Wings birthed the now known pantheon and their inevitable war that shaped the main continent of Erena, the disparate islands of Abaddon, and the kingdoms beyond the Aether.
Io-Sooth: Mortal's Edge - Classic D&D fantasy setting; the second age entertains the birth of the mortal races, created by the first known pantheon. Tiamat and Bahamut - Dragonborn; Pelor - Humans; Morahdin - Dwarves; Corellon - Elves; you get the idea...
Io-Ren: Balance and Ruin - The flames of industry have begun to burn and the mortal races try to harness the power of the gods, ushering in an age of demigods, exploration, and tempting fate. Campaigns: Tuesdays, Thursdays, Knight Owls Season 1
Io-Shar: The Broken Seas - After a cataclysmic event involving an ancient being ripping a hole in the plane of Water, the world has flooded and expanded into an age of naval piracy, massive sea creatures, and temporal storms. Campaigns: Wednesdays, Knight Owls Season 2, Knight Owls Season 3.
Io-Empyr: Cloudsinger - After a sky pirate and his merry band pierced the Veil Of Heaven, cities rose into the sky, forming Clusters of new nations and expanding the world further. Steampunk airships, sky pirates, and tears in the threads of the Feywild and Shadowfell summon a whole new caste of creatures and entities that threaten to take the sky for their own. Campaigns: Cloudsinger (YouTube)
Io-Firma: The Reclamation - Magic is broken. A Prime God is dead. The world is dark and deadly and cold. Shattered psions, enlightened gnolls, ancient detectives, hired guns, and mature themes, this is not an age of heroes. No, this world is just a tad...gray. Campaigns: Gray Owls (21+)
Io-Nixx: The Sundering - Not much is known of this age, as only one adventuring party has caught a glimpse of it. It is a battle; constant and enormous, where literal gods clash in the skies. It may even mark the end of the world as we know it.
So, depending on the age, we can assume that certain gear is available as industry increases. Sooth and Ren are pretty similar, but Ren's adventurers begin to discover the powerful Legacy Weapons from Temm (the first age), tapping into the power of the gods before the turn of the age. Cataclysm changes things in Shar, and the world adapts; ships, naval warfare, cannons, spell cannons, automated ships, subs - Outlaw Star style ship combat. Empire allows more steampunk gunslinging, taking the naval concepts to the air at the peak of an industrial revolution. Then Firma comes along and everything breaks, and it breaks hard; whole classes are gone, or changed dramatically; races disappear, others resurface with new abilities, and no one truly knows how the world works anymore - with magic mostly illegal for the lower class, now we've got to find other ways to get it (drugs, I'm talking about magic drugs).
So without going into too much detail with the various Ages, the following are *mostly* available in all of my games.
I like to employ all that the Player's Handbook has to offer for 5E, but sometimes I draw some extra inspiration from my Pathfinder days (extensive weapon lists), and add on a little extra blades for good measure. None of these are Masterwork (so no +1's, or cutting through resistances), but there might be some other cool perks. I've always been a fan of incorporating more martial arts weaponry (given my own background), and like utilizing die steps to help illustrate a power increase. Also-also, not everything is available at every shop. These custom mundane items, along with other items, might fluctuate depending on supply, demand, harvest, and other such factors age to age. Again, lore and reasoning for the world. The mass production of Duskweave in the third age led to a near extinction of the Displacer Beast packs, and no one's heard of a Pack Lord in eons. Whoops.

Duskweave = made from Displacer Beast pelts, and thus has a smoky dispersal that shifts and moves as the armor moves.
Magic Items and Ammunition
Now, many of these additions are lifted from my Knight Owls Armory, but if you don't normally venture over there, you'd never see them. So here they are anyway for your consideration.
Charged Arrow - 150 gp - in addition to the damage of the bow, this arrow deals 1d6 lightning damage and is consumed upon impact.

Topaz Burst - 250 gp - in addition to the damage of the bow, this arrow deals an additional 2d6 lightning damage and is consumed upon impact.
A good many of the magic items in Io are remnants of the past, but as time marches on, more and more wondrous things become available to the standard market, such as:
Cloak of Shadows - 1000 pp - an adapted Cloak of Elvenkind that grants the wearer advantage on Stealth checks and imposes disadvantage on creatures trying to perceive you. Also, when moving after sunset, roll a set of percentile dice. On a 75 or higher, the shadows wrap around you, granting you Invisibility until you make an attack, cast a spell, or meet direct sunlight.
Ring of Animal Influence - 5100 gp - this ring has 3 charges, and it regains 1d3 expended charges daily at dawn. While wearing this ring, you can use an action to expend 1 of its charges to cast one of the following spells: Animal Friendship (save DC 13); Fear (save DC 13), targeting only beasts that have an intelligence of 3 or lower; Speak with Animals.
Ring of Bravery (Attunement) - 2000 gp - wearing this ring grants you Advantage when saving against becoming Frightened.

Alchemy and Herbalism
Alchemy and Herbalism, especially as it pertains to potion making as a pursuit, has really come to fruition in Io-Shar, where my industry-heavy players reside. They crave that personal control of their universe, and I LOVE IT.
So, potion-making in Io borrows from Skyrim, The Witcher, and my own head, as well as a blend of other home-brew resources dotting the landscape of Reddit, DM's Guild, and the Open-Gaming License. All that being said, let's run it down a bit.
Quick Brewing Overview
In Io, there are a large number of known ingredients that create specific effects in the brewing process, while others might augment or dilute others. Bloodgrass, for example, can be used to add an additional 1d4 to the healing amount for a healing potion you are brewing, but Rubygrass (grown in the Feywild), will actually REMOVE a d4 from the healing (the taste is sharp and difficult to swallow). So we use Herbalism to "enhance" the potion. We call them Enhancements. Some can cancel each other out, while others augment the effects.
Then, there are ingredients that we actually derive the Enchantment from. We treat them as our Core. The intended potion effect. Like using Void Root to brew a Potion of Flying.
Finally, we need a Base. The liquid that we'll be using. Some potions can be brewed in water, while others require Holy Water as their Base, or Salt Water, or Liquor. Specific liquids may also imbue the potion with specific properties.
So, if I want to brew a Healing Potion, I need at least a Base and a Core.
Base: Water. Core: Cherrymoss Extract. Then 3 hours.
If we want, we can mix in some Ground Ephedrana to increase the die step of the healing potion from 2d4 to 2d6. Finish the brew and you've got a "boosted" healing potion that heals 2d6+2 hit points.
And that's one potion. Booyah.
....Experimenting with all of this is going to be A LOT of FUN.
So there's a lot going on, and I haven't even talked about the Prestige Classes or the Legacy Weapons (they're coming, don't worry), but this post has gone on long enough, and hopefully it clears up any confusion from looking at the lists from the Knight Owls armory moving forward. :)
