Eldritch Chains

You learn an ancient ritual that allaws you to never be caught unarmed.

Your Strength or Dexterity increases by 1 to a maximum of 20.

When you take this feat or as a ritual after that, you can bind yourself to a weapon you of choise. 
Once you have bonded a weapon to yourself, you can't be disarmed of that weapon unless you are incapacitated.
You can summon that weapon to your hand as a bonus action on your turn as long as both you and the weapon are on the same plane of existance.

You can have only one bonded weapon at a time. If you attempt to bond with another weapon, you must break the bond with the curent weapon.
