Crafting follows the same basic rules found in the Player’s Handbook (page 187), in addition to those found in Xanathar’s Guide to Everything (starting on page 78) with the following considerations.
Crafting Enhanced Items
Enhanced Items are items, typically weapons or armor, with special non-magical properties. Enhanced Items typically require special materials and knowledge for their construction, so be sure to consult the DM before attempting item enhancements. Items can have multiple enhancements, and can be modified after their construction. The cost of enhancement is listed in gold pieces (gp) and the time it takes to install is based on the value of the item being enhanced (including any previously installed enhancements). These costs are for crafting these enhancements yourself. If you wish to hire an artisan to perform the modifications for you, the costs shown here are doubled.
The following are a selection of enhancements that can be applied to weapons:
Keen Edge (weapon modification). This enhancement doubles the critical range of the weapon, meaning it will score a critical hit on a natural roll of 19 or 20. Only piercing or slashing melee weapons can be given the keen edge enhancement. This benefit doesn’t stack with any other similar effects. Cost: 200 gp.
Balanced. This enhancement applies the finesse property to the weapon, allowing you to use your choice of Strength or Dexterity modifier for the attack and damage rolls. You must use the same modifier for both rolls. Cost: 100 gp.
Serrated Edge. This enhancement applies the bleed property to the weapon, which causes wounds to bleed profusely. Only piercing or slashing melee weapons can have a serrated edge. Cost: 100 gp (1d6), 200 gp (1d8), 300 gp (1d10), 400 gp (1d12).
Brutally Weighted. This enhancement adds weight to the contact end of a bludgeoning weapon, causing it to do more damage. Weapons with this enhancement use a damage dice one size higher than their original value. Cost: 200 gp.
Intuitive Design. This enhancement makes a martial weapon into a simple weapon, allowing characters lacking proficiency in martial weapons to wield it. Cost: 200 gp.
Silvered. This enhancement plates the item with silver, which some monsters are vulnerable to. Cost: 50 gp (for 1 weapon or 10 pieces of ammunition).
Master Crafted. This enhancement is a complete improvement in materials and quality of the weapon, improving both its form and function. Weapons with this enhancement gain a bonus to attack and damage rolls. Master Crafted is not cumulative, meaning you must replace Master Crafted +1 with a Master Crafted +2, or +3, paying the full price for new enhancement. Cost: 200 gp (+1), 400 gp (+2), 800 gp (+3).
Armour & Clothing Enhancements
The following are a selection of enhancements that can be applied to armour and clothing:
Hidden Pockets. This enhancement adds hidden pockets, which can be used to attempt to hide up to 5 lb. worth of items on your character. Cost: 25 gp.
Sound Deadening. This enhancement adds a textile lining to metallic surfaces, which absorbs sound and removes an armor’s disadvantage on stealth. Cost: 50 gp.
Master Crafted. This enhancement is a complete improvement in materials and quality of the armor, improving both its form and function. Armor with this enhancement gains a bonus to its AC. Master Crafted is not cumulative, meaning you must replace Master Crafted +1 with a Master Crafted +2, or +3, paying the full price for new enhancement. Cost: 200 gp (+1), 400 gp (+2), 800 gp (+3).
