You learn an attunement ritual that transforms a one-handed melee weapon into a weaveblade. You perform the ritual over 1 hour, which can be done during a short rest. The weapon must be within your reach throughout the ritual. If the weaveblade was made from a weapon with magical properties, those properties persist.

The weaveblade is a martial melee weapon with the Finesse and Light properties and sheds dim light in a 15-foot radius. The weapon is composed of a hilt that, while held in your hand, can emit a blade of pure radiant energy without requiring an action. The blade deals radiant damage and its damage die is 1d8. You can use the weaveblade as your spell casting focus.

You can have up to two weaveblades created this way. If you attempt to create a third weaveblade, you must break your attunement with one of the other two weaveblades, which reverts the transformation back into the weapon it was previously.

Proficiency with a Rapier allows you to add your proficiency bonus to the attack roll for any attack you make with it.
