Level 3: Sacred Weapon

When you take the Attack action, you can expend one use of your Channel Divinity to imbue one Melee weapon that you are holding with positive energy. For 10 minutes or until you use this feature again, you add your Charisma modifier to attack rolls you make with that weapon (minimum bonus of +1), and each time you hit with it, you cause it to deal its normal damage type or Radiant damage.

The weapon also emits Bright Light in a 20-foot radius and Dim Light 20 feet beyond that.

You can end this effect early (no action required). This effect also ends if you aren’t carrying the weapon.

Soul binder

You gain the ability to bind up to 3 Souls to a weapon or armor, giving it additional attributes. Any soul you encounter will be an option

The quality is determined by the quality of the Soul (to determine the quality, a d10) (this determines the amount of + AP or damage...)

The Attributes aredeterminedt by the details of the Soul. Example: A blacksmith would give you (if applied to your armor) additional AP or Quality Upgrade, Additional damage or quality on non magic wepons.  A Dragonborn would give on a weapon (based on its color) additional damage of the same kind whif low quality, and changes the damage type (1d4)  whif good or better quality.

To decide if the soul is willing, roll a d20 + persuasion - the number of souls already in the weapon. If the roll is over 10, the soul goes in; if not,t you can force the soul into it. Which has the consequence of being always the worst quality.
