Magic Items

Wondrous item, common (requires attunement by a spellcaster)

Etched with eldritch runes, this 1-inch-diameter ruby allows you to use a simple or martial weapon as a spellcasting focus for your spells. For this property to work, you must attach the ruby to the weapon by pressing the ruby against it for at least 10 minutes. Thereafter, the ruby can't be removed unless you detach it as an action or the weapon is destroyed. Not even an antimagic field causes it to fall off. The ruby does fall off the weapon if your attunement to the ruby ends.
The Undisputed Multiversal Championship belt is made of polished gold and inlaid with decorative gems. The blood-red rubies inset into the belt can be removed only by the reigning Multiversal Champion. Once removed, they function as rubies of the war mage.

You gain one 9th-level spell slot, provided that you already have one.

Imbued with the power of the Multiversal Championship, you gain an additional 9th-level spell slot, provided that you already have one. This epic boon, granted only to the greatest champions, enhances your magical prowess, allowing you to cast the most potent spells with unparalleled mastery.
Note: In T4 only you can replace all consumables with a boon; while a boon can be given to a character that is not yet 20th level it does not take effect until they reach that level. You need to include this information in the adventure.

Ring, rare
You have Resistance to Force damage while wearing this ring. The ring is set with pearl.
