Item Crafting Rules

Scavenging:
After a fight, or during short/long rests, players can call for a scavenging check to look for either specific types of material or just to gather the remains of anything they might have found or may find in the surrounding area. Depending on your skill check, either Investigation, Survival, Medicine, Nature, Arcana, you may roll a number of D12’s and gather that many types of scrap based off the DM’s discretion. Each area or kill can be scavenged twice. Any further attempts afterwards may incur story-based outcomes or effects. 

Outcomes:
1-5 1d12
6-10 2d12
11-15 3d12
16-20 4d12
20+ 4d12 +special

(liquids require 10 units to fill up a standard glass bottle)

Each unit of scrap weighs 1lb

Crafting rules (number of scrap needed to make the item):
 Common items: 8

Uncommon items: 16

 Rare items: 32

Very Rare items: 64

Artifacts: 128

Legendary items: 256

magic items can be subjected to various effects that can either temporarily suppress or fully drain the magic from an item

in the case of magic drain, items can resist a number of magic drain effects depending on their rarity shown in the table below. Campaign specific Legendary and Artifacts are immune unless the DM informs you of otherwise. Fixing magic items can be done physically with the mending spell, but to repair the magical runes or circuits requires a wizard/artificer and an associated tools check, the dc is listed on the tables below:

An attempt at a simpler or rules lite version of the crafting rules, as the previous version is extensive 

Scavenging:
After a fight, or during short/long rests, players can call for a scavenging check to harvest Special parts of interest from a monster, Monster hunter style. Using either Investigation, Survival, Medicine, Nature, Arcana, you roll to see how many item charges you get from the creature, plantlife, or environment. Each area or kill can be scavenged once (Once per day in the case of traveling on the road). Any further attempts afterwards may incur story-based outcomes or effects. 

Outcomes:
1-5 1 charge
6-10 2 charges
11-15 3 charges
16-20 4 charges
21+   5 charges

Item application is simplified. Each Special Item Charge can be used in 2 ways

• to make an item of your choice as long as you have the tool proficiencies
• as a special Material used as part of the component of a spell. (If the spell does not have an inherent material component, then it gains a material and somatic component when you use the Special Item Charge) 

Item effects are based off the creature it was initially taken from.  DC's, damage dice and the like are taken straight from the statblock.  

ITEM CREATION:
the special item is described on obtainment and given 3 example abilities that could be crafted into an item.
The DC for crafting an item taken:

8+ Total creature hit die (so if a creature has 11d8 hit die, you add 11)

The Rarity of the item is determined by the chart below:

The DC, damage output, or statistics of an item effect is the same DC as the monster. To change the DC you have to sacrifice an item in your possession of a rarity equal to the DC that you want. Damage dice numbers also stay the same as the creature unless an item that has more damage dice of the same type is sacrificed.

Any item that gives resistance requires 2 Special item charges, 3 for immunity

If you succeed the Craft Check by 10 or more you get a free bonus on one of the Item's stats. If you fail the craft check you produce an item with some drawbacks based off of materials expended. A Nat 1 expends the item and causes a random side effect based off the crafting process.

Creating items can be done with different types of scrap. Item creation checks will be tool checks against a DC= 10+amount of extra scrap used (the additional scrap outside of the scrap needed to make a base item)

• Gloves = 2 scraps

• Boots = 4

• Pants = 6

• Shirts = 8

• Armor = 10

• Weapons = 9

Artificers are able to shorten the time of crafting magical items to a long rest by using 1 charge of their magical tinkering and recycling an existing magic item that has a similar effect or theme.

Miscellaneous items require between 1 to 4 scrap to start. For potions & poisons it takes 3 scrap base. Adding in the types of scrap you scavenge along the way will allow you to modify potions and poisons you make. If you are proficient with the Alchemist kit, Herbalism kit, or Poisoner's Kit you may roll a tool check (DC = number of additional scrap added) to attempt to make double the amount of the brew, a critical success means you produce 3 bottles of your chosen potion. Base poisons created have the following features

• have a DC13.
  
• For damage, it starts off with 2d6
  
• Applications is always injury. *ingestion automatically increases save DC by 1
  
• Timing is instantaneous, and if you want healing - it starts off with 2d4+proficiency and intelligence or wisdom.
• The poison lasts for 1 minute with the afflicted creature making another saving throw at the end of their turn
  

You can upgrade these individual stats by applying more materials in the following ways:

• For each scrap you can upgrade the DC by 1 to a limit of 22. 
• You can change the poison/potion application with 1 scrap
  

• For the damage you can up the damage dice by 1 per scrap. For 2 scrap, you can change the application type or damage die. 

• For the timing, every piece of scrap you add provides an hour to the activation condition. 

• The duration of the poison's effect increases to 10 mins with 1 added scrap, 1 hour for 2 scraps, 1 day for 8 scraps, 1 week for 16 scraps

• The creature makes no further saving throws for the duration of the poison effect for 12 scrap

  
  

Additional conditions can be added to a poison, but requires a certain number of scrap per condition as seen in the list below.

• • Annoying costs 1 additional scrap

  • Inconvenient require 2 additional scrap

  • Deadly requires 4 additional scrap

  • You may add a Biteback condition for 2 scrap, which is an additional effect that activates when the poison is neutralized magically. If the Biteback includes another condition you must pay the cost for the additional condition.
    

When the poison is activated it lasts for 1 minute. At the end of each of their turns the creature can make a saving throw to overcome the poison.  This part of the poison can be augmented in the following ways with scrap

• The duration of the poisons increases to 10 mins with 1 added scrap, 1 hour for 2 scraps, 1 day for 3 scraps, 1 week for 4 scraps
  

• The creature has disadvantage on the saving throws for 3 scrap
  

• The creature makes no further saving throws for the duration of the poison for 6 scrap
