Rune Squire

You have learned about the ancient practice of rune carving and have used that knowledge to experiment with runes yourself. Choose one rune from the fighter's Rune Knight subclass (detailed on pages 44-46 in Tasha's Cauldron of Everything). Whenever you finish a long rest, you can touch one object and inscribe the rune you choose onto the object. To be eligible, an object must be a weapon, a suit of armor, a shield, a piece of jewelry, or something else you can wear or hold in a hand. The rune you choose remains on an object until you finish a long rest, in which you can remove and inscribe the rune you choose onto a different object. If the rune you choose requires a saving throw, your save DC equals 8 + your proficiency bonus + your Constitution modifier. You must follow the rules on the rune you choose in order to use it properly during combat. The Hill Rune and Storm Rune runes are unavailable for you to choose, even if your character is 7th level or higher.
