Boon of Sentient Bonded Weapons

Your wife, Jane, didn't leave you alone with nothing when she died. As a contingency, she left an ai copy of her mind in nanites to still be with you even after death. Guided by your heartband pact, they will envelop weapons you bond with, improving them beyond what you were capable of before. Most importantly, where the weapons before had no sentience, now they carry Jane's sentience that you can call upon for aid.

Phalanx Protocols: The nanites are capable of replicating Jane's quick thinking intellect to help survive dangerous situations. During initiative, extra phalanx protocols become available to you. When you would be hit by an attack or are forced to make a saving throw, you can use your reaction to expend a number of phalanx charges up to your charisma modifier to add a bonus to your armor class or saving throw equal to the number of charges expended, potentially causing the attack to miss or for you to pass the save. As a bonus action, you can expend a phalanx charge to gain expertise for one minute with your bonded weapons. Out of initiative or not in combat, the weapons can be consulted with. As an action out of combat, you can expend a phalanx charge to use your bonded weapon’s sentience ability modifier for intelligence and wisdom ability/skill checks.

Sentience: Jane's mind is within the nanites, thus your weapons speak as well and might not agree to do evil or malicious aligned acts. They have an intelligence score of 20, a wisdom score of 20, and a charisma score of 12. They are neutral good aligned.
