Magic Item Creation by NPC

The difference in magic item crafting rules between the Dungeon Master's Guide (DMG) and Xanathar's Guide to Everything (XGtE) lies primarily in their approach to cost, time, and the inclusion of specific crafting components. The DMG offers a framework focused on gold cost and time based on item rarity, while Xanathar's introduces a more detailed system involving exotic materials and adventure-based acquisition

 

Using DMG (Pg# 128 /129) not Xanthar due to no quest or rare ingredients by PC. Assuming we are asking someone in the city to do this for us. 

Magic Weapon’s

+1 Uncommon - 500 gp - 20 days / x2.8 Weeks

+2 Rare - 5000 gp - 200 days / 28.5 Weeks / 6.5 Months

+3 Very Rare - 50,000 gp - 2000 days / 285.7 Weeks / 131.4 Months / 5.48 Years

+4 Legendary - 500,000 gp - 20,000 days /  2857 Weeks / 1315 Months / 110 Years

NPC’s Time and Money Costs 

+1 Uncommon - +30 gp 

+2 Rare - +300 gp

+3 Very Rare - +3000 gp

+4 Legendary - +30,000 gp

Asking someone in the city to undertake this great expense of time and money will result in them charging for their work beyond what is presented in the guide. The guide assumes YOU are doing the work. 

Presented here are MY npc’s rates adjusted for the campaign.
