Attuned Weapon

You gain proficiency with a single martial weapon. You learn a ritual that creates a magical bond between yourself and this weapon. You perform the ritual over the course of an hour, which can be done during a short rest. The weapon must be within your reach throughout the ritual, at the conclusion of which you touch the weapon and forge the bond. Once you have bonded a weapon to yourself, you can't be disarmed of that weapon unless you are incapacitated. If it is on the same plane of existence, you can summon that weapon as a bonus action on your turn, causing it to teleport instantly to your hand.

You may have only one weapon bonded at a time. If you attempt to bond with a second weapon, you must break the bond with the first.

In addition, when attacking with a bonded weapon that lacks the two-handed property, you can use your Intelligence modifier, instead of Strength or Dexterity, for the attack and damage rolls.

This weapon acts as an Arcane Focus.
