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 dice are 3d6. 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.

This item adds proficiency with Firearms, this only applies to the weaveblade. This weapon will show up on your character sheet as a ranged weapon. This is considered a melee weapon with a reach of 5 ft. Ignore all references to Ammunition, Firearms, Range, or Reloading. Ignore everything after this point.

It’s up to you to decide whether a character has proficiency with a firearm. Characters in most D&D worlds wouldn’t have such proficiency. During their downtime, characters can use the training rules in the Player’s Handbook to acquire proficiency, assuming that they have enough ammunition to keep the weapons working while mastering their use.
