The Collector

The Collector is a Patron that seeks possessions that it deems worthy and appropriately enticing. This can range from a polished set of silverware to a particularly popular person's identity in it's entirety.

Eye for Quality

You can now at will detect items that the Collector would enjoy as long as they are not protected by magic. 

You also gain the ability to sacrifice these items to gain an extra additive to your attacks, small items gaining a +1 bonus and larger items giving +2 to your next attack roll

At level 10 add 1 to each sacrifice

At level 15 add 2 to each sacrifice

At level 20 add 3 to each sacrifice

Identity Thief

Starting at 6th level you can steal the identity of any creature you grapple or kill. Doing so reforms the minds of everyone who doesn't see you do this to belive you have always been this person, and they will treat you the same way the treated the person who's identity you've taken. 

The person you've stolen the identity of will be forgotten by anyone who didn't witness you take it. If they are alive they can be remembered with a one time Wisdom save Dc 20 or else they are forgotten forever. 

You can use this ability a number of times equal to your Constitution modifer plus your level and your charges are regained every short or long rest. 

Amnesia

Pick one target of your choice, this target completely forgets who they are, and all associations with themselves.

They can recall who they are with a Wisdom save Dc 20 but with each failed attempt the Dc gets 5 points higher.

If a target saves they become permanently immune to all collector abilities and become touched by the Collector, allowing them to remember and recognize anyone who has had their identity stolen or forgotten if they knew them prior.

You can use this feature a number of times equal to your Charisma Modifier and you regain these charges every short or long rest.

Goodbye.

When you make a melee attack against a creature you can force them to make a Wisdom saving throw Dc 18 or they will be banished to the Domain of the Collector. 

This creature is instantly forgotten by anyone not marked by the collector as if they had never existed. Only the caster remembers that someone had existed though the details are unclear.

This feature can be used a number of times equal to your Charisma modifier. The charges are regained every Long Rest.
