Wargear

Protection

Mundane armor is not commonly worn in the Dodekapolis, enchantments being far more preferred. All the same; shields, leather, chain, plate, and even bespoke suits of plate can be found in bazaars for very reasonable prices. These armors are assumed to be layered; chain includes leather, and plate includes chain and leather. If you are just ‘upgrading’ your armor, you can subtract the prices of the armor you already have. For example, if you already have leather armor and want to add chain to it, it might (prices can vary) cost 130 copper instead of 180. Bespoke armor is the exception to this. By definition, the entire set is made to measure so it must all be bought together at once. This layering is also reflected in the weights listed below.
Something’s armor is what you subtract from any applicable source of damage that is done to you.
Something’s defense is a bonus you get to the required attack roll to hit you.
Armor and defense only apply to certain attacks and/or sources of damage, and these are noted in the description of the item.
For more details on the rules of combat, see the page on Warfare.

Weapons

Like armor, most mundane weaponry is not terribly favored in the Dodekapolis. Heavy, large, and antiquated, most citizens balk at the idea of carrying a sword, axe, or bow around a city. Stiletto daggers however do have some favor among citizens from all walks of life. More on weapon abilities, range, damage, and wounding can be found on the page on Warfare.

Firearms were the hot new thing until the Paroxysm brought ruin to the Prime Material. The specific salt used in their alchemical ammunition was unique to an intelligent and expanding coral colony in the Nidaj Bay, which was at the center of the surge of energy which collapsed the Deepline. As far as anyone knows, the salt is gone for good and the ammunition that existed three years ago is all there ever will be. Ammunition prices have skyrocketed while the firearms themselves have dropped in price, but it varies wildly based on circumstances.

Torch: Weapon either simply glows or is ablaze with a heatless and smokeless flame, shedding light as a torch. Cost: 25 to 40 copper. An additional 20 to 30 copper can be spent to make it activatable

Wands are the weapon of choice for most citizens. They’re small, light, and skill in using them has a perception of sophistication and class.
Wands
Battle:Available in acid, cold, fire, force, lightning, and sonic varieties. With a successful attack, wielder can deal d6 damage of the appropriate type to a target within 30 feet. Cost: 7 to 9 copper per charge, up to a maximum of six charges.
Telekinesis: As a reaction, wielder can expend a charge to gain 5 pound telekinesis within 30 feet of their line of sight until the end of their next turn. Cost: 11 to 13 copper per charge, up to a maximum of six charges.

Extra Charges
Some items have charges and are priced by how many charges they start with. Unless you’re having something made custom or are buying from a discount goods vendor, items off the shelf will be made with the normal maximum amount of charges. It is possible though to “overcharge” an item, though many artificers refuse to do so. The work is risky and dangerous, not only endangering the item but the life and limb of the artificer. Overcharging has a tendency to result in small but very lethal explosions when not done very carefully by skilled hands. Each additional charge costs the maximum value of the existing charges. A proficient artificer can overcharge an item by 5 charges, an expert by 8, and a master by 10.
