Brother of Gold and Bone

You learn from the Brothers of Gold and Bone the secret and ancient art of creating gold infused with holy energy and how to use it to supplement your equipment.

You can spend a month and 20x the value of the item in gold to gild a nonmagical weapon or armor that contains metal. You must have access to blacksmith tools and a forge for the whole month. Each time you stop, 1 days worth of progress is lost. You must keep the weapon or armor on you at all times until the item is fully infused or all progress is lost. Once you complete it, you must speak the ancient words "I offer the bones of my foes to cleanse this gold" in dwarvish and equip the item. You must then strike the final blow on an enemy of dwarvenkind (DM note: This is a dragon, drow, or giant of CR 13 or higher) or a treasured friend while using or wearing the item and say "Holiest of metals, give me your strength to defeat my enemies" in dwarvish to complete the ritual. You gain the benefits of a long rest immediately upon completing the ritual. You can only work on one item at a time and only you can use the item. 

After fully imbuing an item, it gains the following benefit depending on if it is a weapon or armor:

Weapon: The weapon gains finesse, light and thrown (20/60) if it doesn't already have them. The weapon deals an extra 1d6 radiant damage on a hit. You can use an action to call the weapon to you if it is within 100ft of you, making a melee attack against up to one creature between you and the weapon. The weapon travels in a straight line and cannot move through sturdy objects or around corners.

Armor: The armor loses any strength requirements and any Disadvantage on stealth. When you reduce a hostile creature to 0 hit points, you may gain temporary hit points equal to your total level among all classes. While you have these hit points, the armor glows, giving you disadvantage on stealth checks. When you are hit with an attack, you can expend your temporary hit points to cause the armor to flash brightly and blind the attacker, forcing them to reroll their attack and potentially miss.
