Crafting Magic Items

NOTE: As discussed and settled on 5/15/2015, here are a few clarifying notes on the crafting rules:

1. In regards to the Caster Level (CL) used for the DC;
(a) It’s 3x the enhancement bonus
(b) It’s the CL listed for a weapon/armor special property
© if you are adding both an enhancement and property at once, it is the higher of the two.

2. For the “flat rate” special properties, they are external to the enhancement bonus system (bonus squared x 2000GP for weapons or 1000 GP for armor) in terms of Price, crafting time, and cost. However, as a House Rule, each of these “flat rate” properties will count as a +1 towards the total +10 enhancement.

3. Curses can not be removed from items.


Here are the rules, cut and pasted, somewhat edited for space, along with links to weapon & armor properties.

To create magic items, spellcasters use special feats which allow them to invest time and money in an item’s creation. At the end of this process, the spellcaster must make a single skill check (usually Spellcraft, but sometimes another skill) to finish the item. If an item type has multiple possible skills, you choose which skill to make the check with. The DC to create a magic item is 5 + the caster level for the item. Failing this check means that the item does not function and the materials and time are wasted. Failing this check by 5 or more results in a cursed item.

Note that all items have prerequisites in their descriptions. These prerequisites must be met for the item to be created. Most of the time, they take the form of spells that must be known by the item’s creator (although access through another magic item or spellcaster is allowed). The DC to create a magic item increases by 5 for each prerequisite the caster does not meet. The only exception to this is the requisite item creation feat, which is mandatory. In addition, you cannot create potions, spell-trigger, or spell-completion magic items without meeting its prerequisites.

While item creation costs are handled in detail below, note that normally the two primary factors are the caster level of the creator and the level of the spell or spells put into the item. A creator can create an item at a lower caster level than her own, but never lower than the minimum level needed to cast the needed spell. Using metamagic feats, a caster can place spells in items at a higher level than normal.

Magic supplies for items are always half of the base price in gp. For many items, the market price equals the base price. Armor, shields, weapons, and items with value independent of their magically enhanced properties add their item cost to the market price. The item cost does not influence the base price (which determines the cost of magic supplies), but it does increase the final market price.

In addition, some items cast or replicate spells with costly material components. For these items, the market price equals the base price plus an extra price for the spell component costs. The cost to create these items is the magic supplies cost plus the costs for the components. Descriptions of these items include an entry that gives the total cost of creating the item.

The creator also needs a fairly quiet, comfortable, and well-lit place in which to work. Any place suitable for preparing spells is suitable for making items. Creating an item requires 8 hours of work per 1,000 gp in the item’s base price (or fraction thereof), with a minimum of at least 8 hours. Potions and scrolls are an exception to this rule; they can take as little as 2 hours to create (if their base price is 250 gp or less). Scrolls and potions whose base price is more than 250 gp, but less than 1,000 gp, take 8 hours to create, just like any other magic item. The character must spend the gold at the beginning of the construction process. Regardless of the time needed for construction, a caster can create no more than one magic item per day. This process can be accelerated to 4 hours of work per 1,000 gp in the item’s base price (or fraction thereof) by increasing the DC to create the item by 5.

The caster can work for up to 8 hours each day. He cannot rush the process by working longer each day, but the days need not be consecutive, and the caster can use the rest of his time as he sees fit. If the caster is out adventuring, he can devote 4 hours each day to item creation, although he nets only 2 hours’ worth of work. This time is not spent in one continuous period, but rather during lunch, morning preparation, and during watches at night. If time is dedicated to creation, it must be spent in uninterrupted 4-hour blocks. This work is generally done in a controlled environment, where distractions are at a minimum, such as a laboratory or shrine. Work that is performed in a distracting or dangerous environment nets only half the amount of progress (just as with the adventuring caster).

A character can work on only one item at a time. If a character starts work on a new item, all materials used on the under-construction item are wasted.

It is possible to enhance or build upon an existing magic item. Only time, gold, and the various prerequisites required of the new ability to be added to the magic item restrict the type of additional powers one can place.
The cost to add additional abilities to an item is the same as if the item was not magical, less the value of the original item. Thus, a +1 longsword can be made into a +2 vorpal longsword, with the cost to create it being equal to that of a +2 vorpal sword minus the cost of a +1 longsword.

MARKET (BASE) Price
Armor bonus (enhancement) = Bonus squared x 1,000 GP
EXAMPLE: +1 shield = 1000GP
(meaning 500GP & 1 day to create)

Weapon bonus (enhancement) = Bonus squared x 2,000 GP
EXAMPLE: +1 sword = 2000GP
(meaning 1000GP & 2 days to create)

If you need another character to supply one of an item’s requirements (such as if you’re a wizard creating an item with a divine spell), both you and the other character must be present for the entire duration of the crafting process. If the GM is using the downtime system, both you and the other character must use downtime at the same time for this purpose.

Creating Magic Armor

To create magic armor, a character needs a heat source and some iron, wood, or leatherworking tools. He also needs a supply of materials, the most obvious being the armor or the pieces of the armor to be assembled. Armor to be made into magic armor must be masterwork armor, and the masterwork cost is added to the base price to determine final market value. Additional magic supply costs for the materials are subsumed in the cost for creating the magic armor—half the base price of the item.

Creating magic armor has a special prerequisite: The creator’s caster level must be at least three times the enhancement bonus of the armor. If an item has both an enhancement bonus and a special ability, the higher of the two caster level requirements must be met. Magic armor or a magic shield must have at least a 1 enhancement bonus to have any armor or shield special abilities.

If spells are involved in the prerequisites for making the armor, the creator must have prepared the spells to be cast (or must know the spells, in the case of a sorcerer or bard) and must provide any material components or focuses the spells require. The act of working on the armor triggers the prepared spells, making them unavailable for casting during each day of the armor’s creation. (That is, those spell slots are expended from the caster’s currently prepared spells, just as if they had been cast.)

Creating some armor may entail other prerequisites beyond or other than spellcasting. See the individual descriptions for details.

Time Required Crafting magic armor requires one day for each 1,000 gp value of the base price.

Feat(s) Required: Craft Magic Arms and Armor.

Skill(s) Required: Spellcraft or Craft (armor).

Creating Magic Weapons

To create a magic weapon, a character needs a heat source and some iron, wood, or leatherworking tools. She also needs a supply of materials, the most obvious being the weapon or the pieces of the weapon to be assembled. Only a masterwork weapon can become a magic weapon, and the masterwork cost is added to the total cost to determine final market value. Additional magic supplies costs for the materials are subsumed in the cost for creating the magic weapon—half the base price of the item based upon the item’s total effective bonus.

Creating a magic weapon has a special prerequisite: The creator’s caster level must be at least three times the enhancement bonus of the weapon. If an item has both an enhancement bonus and a special ability, the higher of the two caster level requirements must be met. A magic weapon must have at least a 1 enhancement bonus to have any melee or ranged special weapon abilities.

If spells are involved in the prerequisites for making the weapon, the creator must have prepared the spells to be cast (or must know the spells, in the case of a sorcerer or bard) but need not provide any material components or focuses the spells require. The act of working on the weapon triggers the prepared spells, making them unavailable for casting during each day of the weapon’s creation. (That is, those spell slots are expended from the caster’s currently prepared spells, just as if they had been cast.)

At the time of creation, the creator must decide if the weapon glows or not as a side-effect of the magic imbued within it. This decision does not affect the price or the creation time, but once the item is finished, the decision is binding.

Creating magic double-headed weapons is treated as creating two weapons when determining cost, time, and special abilities.

Creating some weapons may entail other prerequisites beyond or other than spellcasting. See the individual descriptions for details.

Time Required Crafting a magic weapon requires 1 day for each 1,000 gp value of the base price.

Feat(s) Required: Craft Magic Arms and Armor.

Skill(s) Required: Spellcraft, Craft (bows) (for magic bows and arrows), or Craft (weapons) (for all other weapons).
