D&D 5e House Rules: Crafting, Materials, Magic Items and Economics

This is my first draft and there is likely to be some minor changes going forth.

The basic rules for crafting make sense when dealing with simple crafting but quickly breakdown as unrealistic when dealing with let’s say a goldsmith crafting a gold ring with a large emerald setting. At 5 g.p.’s a day the ring would take months to craft while a silver ring could take weeks or at least several days even if plain and unadorned.

So, in the rules that follow I will cover how each item has a complexity of design, a material that can modify the difficulty in successful crafting, a level of quality which can modify the value and/or functionality, and how long it takes to craft plus some basic economics on running a business or being an employee for those characters who focus on being a business owner or guildmember or master in their downtime. The more skillful the smith the less raw material is wasted or lost in the smithing process.

A common material could be a malachite stone, copper, bronze, iron, oak wood, beaver fur, cow leather, or granite. Common materials have a base minimum value of 1 g.p. a day for determining amount of work done and cost of materials though this could be modified by local conditions, prosperity of the region, and supply and demand. The base time to craft is the basic cost for the item as listed in the PHB such as 10 g.p.’s for a battle axe.

Uncommon materials could be a garnet or agate, dwarven steel, common mithril, silver, electrum, Fey-bronze, iron-oak, mink fur, wyvern leather, or marble. These have a base minimum value of 20 g.p. a day for determining amount of work done and cost of materials though depending on the material the costs can far exceed that starting value. The crafting time using most uncommon materials is twice as long as the value listed in the PHB such as 20 g.p.’s for a dwarven steel battle axe though some uncommon materials may be harder to work and have an higher multiplier.

Rare materials could be a ruby or emerald, noble mithril, admantine, gold, platinum, Ebon Ash wood, Holy Willow, fur from a Feywild Polar Bear, Shadow touched stone, and Dragon teeth or scales. They have a base minimum value of 100 g.p. a day for determining work done and cost of material. The crafting time using rare materials is usually five times that of the basic cost for the item though gold is easier and only has double the normal time when used for jewelry.

Very Rare materials could be a star ruby, royal mithril, primal gold, fur from a Primal Cave bear, a claw from an ancient dragon, marble carved from Mount Meru, and other such potent or valuable material. They have a base value of 500 g.p. a day for determining work done and cost of material. Crafting time is usually five times that of the basic cost fro the item.

Legendary materials might be a gem grown from the heart of an elder tree in the sacred grove of the first elven nation that holds an echo from that ancient time, a scale from Tiamat, iron ingots mined by undead dwarven masters in Hades and smelted by Hephaestus himself, locket of hair from the Freya, or Hide from a slain Nemean Lion.

Overhead per day of crafting is typically around 1 g.p. and covers everything from sales and property taxes, bribes, expendables such as wood or coal to burn at a smithy, and paperwork.

Labor and Lifestyle costs are based partly on the prosperity, trade, and urbanity of the locale but commonly sit at 5 s.p. a day worth of lifestyle and 1 g.p. a week for wages for apprentices and at least 1 g.p. in pay or lifestyle for a journeyman, and 5 g.p.’s a day or more for a master.

The Labor “Retail Value” equals Proficiency/Familiarity bonus + Ability Score Modifier + Tool Quality Modifier

For example:

A human Journeyman smith crafting a warhammer with iron has a Strength Modifier of +1 and a Proficiency of +2 with average “apprentice” tools that provide no bonus would do 3 g.p.’s of labor a day. This would add to the 1 g.p. in material and 1 g.p. in overhead so the total retail value of labor would be 5 g.p. a day. The smith would complete the warhammer in 3 days since the cost in the PHB is 15 g.p. There would be 6 g.p. worth of material and overhead involved and if the smith sold the warhammer to a merchant for 9 g.p. then he would have made 3 g.p. for 3 days of work if working for himself and probably less if an employee with a typical employee making a basic lifestyle for the 3 days and maybe half a gold in wages. If the smith was lucky and an adventurer commissioned the warhammer for retail price then the smith would’ve made 9 g.p. for 3 days of work or 3 g.p. a day.

A dwarven master smith crafting a dwarven warhammer made of royal mithril for his king. She has a Strength Modifier of +5 and a Proficiency of +5 with rare crafting tools providing a +3 bonus would do 13 g.p. of labor a day. Each day of labor would use 500 g.p. worth of material as royal mithril is treasured for its ability to attract legend and thus magic making it highly likely to become enchanted through use over time. The dwarven smith completes the royal warhammer in five days (65/13 = 5) using 2500 g.p. worth of material and 5 g.p. in overhead. The royal commission paid 5000 g.p. so she made close to an hefty 500 g.p. a day profit though if the GM used my optional rule requiring a DC check after completion of the item and failed then that is risk of wasting a lot of expensive materials!

Optional Rule: Crafting Failure

Each item has a DC to craft as a base item which can be modified by the type of material. Difficult to work materials place the craftsman with a Disadvantage on their roll. Easy to work materials give Advantage on their DC check. Simple products lower the DC category by one while complex products can greatly increase the DC like a master poisoner’s secret recipe of instant death or the careful and precise grinding and glasswork necessary for a quality spyglass or building a massive cathedral. Failure means the item is unusable or if the roll was close has an hidden or obvious flaw such as a sword that works fine until it gets below freezing when it becomes brittle or in the case of art just doesn’t show the emotion intended or just isn’t any good.

The base DC (common) for most weapons, most small objects of art, simple housing, is the number of days spent crafting times 5 which creates a weapon or item at the level of quality of the materials.

The base DC (uncommon) for longbows, most armor, most medium objects of art, basic housing is the number of weeks spent crafting times 5.

The base DC (rare) for advanced tailored armors, vehicles, fortifications, and most large objects of art is the number of months spent crafting times 5.

The base DC (very rare) for advanced and large sea vessels or mansions, keeps, and cathedrals is the number of seasons spent crafting times 5.

The base DC (legendary) for flying citadels, planar ships, 1000 foot bronze statues, great Pyramids, and other world class projects is the number of years spent crafting times five.

Optional Rule: Exceptional Success

When you double the base DC on your crafting roll the Quality of the item goes up by 1 category. A common item that would be limited to a common enchantment now counts as an uncommon item. If you triple the base DC than it goes up by 2 categories et cetera.

Optional Rule: Item Quality and Enchanting

A quality crafted item like all things that exhibit excellence and develop interesting stories tend to attract and collect magic. A knowledgeable and powerful character can take advantage of this and craft items with the potential to become magical over time or even weave magic into the crafting of the item at the beginning. As is often the case items with minor magics at creation can achieve Legendary status when wielded by great heroes or villains or as the case of the Moonblades of the Elves of Toril when wielded by generations of heroes.

The quality of the item must match or exceed the level of the enchantment. A Legendary Quality sword could accept any level of enchantment while a common blade would be limited to a common enchantment. A common quality blade could develop into a Legendary Artifact but wouldn’t be crafted it would be earned by the blade.

When enchanting an already crafted item or when enchanting while crafting the artificer rolls either Arcana, Alchemy (potions), Nature, or Religion depending on the type of character and the type of enchantment. Any character with a Class can enchant an item though those that require a spell require a spellcaster to make who knows and can cast the spell.

An alternative rule is to replace the 25 gp in labor for enchanting with the ability modifier + proficiency + tools (Enchanting Lab or Zen garden or Sacred Grove or Cathedral Chapel) times 5=X g.p.

A cleric of a charismatic religion could focus his passion of his zeal to create an holy avenger while a monk could spend her day dwelling on the riddle of the wolf while raking sand and trimming bonsai trees and would use Wisdom and Nature and a druid could craft a magical staff while carving in the tranquility of the sacred grove.

If the character is crafting and artificing at the same time the total time crafting is doubled as long as the enchantment matches the material quality and the artificing. This increases the material cost spent on the item as it will take longer to craft. The artificing DC matches the crafting DC.

Crafting magical potion batches has a DC of 5 plus 5 for per level of the spell and requires common materials for a 1st level spell and one tier better for each level after that. For each level of material surpassing the requirement the DC is lowered by 5. The base cost used for how long it takes to craft the potion is the DC of the Alchemy task. Legendary ingredients allows up to 9th level potions though few would try to attempt that. Each batch has 1d6 potions of the type crafted.

If adding an enchantment to an existing item the time for artificing and the DC for artificing is the same as shown on the optional rule for Crafting Failure with the number of days, weeks, months, seasons, or years determined by the DM based on the item and what the enchantment is. A common enchantment has a DC of 5, uncommon 10, rare 15, very rare 20, and 25 for Legendary.

For example:

An elven smith Leiwand is crafting and artificing a Longbow which has a base retail price of 50 g.p. He and his adventuring party had gone deep into the Feywild and in the course of battle a treant was slain by a fire giant and some of the wood was still good so he harvested it. Using leather from a young adult red dragon he slew a few years ago for the grip and gut sinew from a fey saber tooth tiger he begins his crafting of a rare magical item. It will have a +1 to attack and damage and sets the arrows on fire as they get fired adding 2 points of fire damage to each arrow plus an extra +3d6 of damage towards Giants and Giantkin. The adjusted retail cost is 250 g.p. and the smith has a proficiency of +5 plus Expertise and a Dexterity of +4 and rare tools to provide a +3 bonus and a total of +17 and 15 days to make. This rounds up to 3 weeks which is doubled for a total of  6 weeks because of artificing. The DC for crafting is 15 and for artificing is Nature + Wisdom against a DC of 15. He rolls a 14 for a total of 31 and that doubles his craft dc so the quality goes from Rare to Very Rare. The artificer roll succeeds as well. The Quality level is Very Rare but the enchantment is Rare so the item has room to grow.


Marekanos the Barbaric’s Battle-Axe Chilldeath had been a favorite of his father and had at the time he claimed it a common enchantment but after slaying the Crimson Necromancer and the Demi-Lich of Kora it became far mightier by absorbing both the Legend and a share of the magical energies that were expelled at their destruction. After slaying and bathing in the blood of the tyrant Dragon-King Torenus who was an ancient white dragon the Battle-Axe earned its final name as it protects the wielder from the cold and cold magic while also dealing chilling and necrotic damage alongside every strike. So, a minor magical weapon became an artifact of incredible power during the century of adventuring the Half-Elven barbarian survived and continued its adventures in the hands of first his half elven daughter Tiana from an human mother as Chillend rejected the other daughters who didn’t express any elven features and after her death by her half sister the half elven Alrekanos born of an elven mother as Chillend rejected those kin who expressed only elven traits.
