Blood Hunter unique ability help

[sammyp03]

Hello all, I have a blood hunter playing in my upcoming game. He is going with the Order of the Lycan. I have a unique ability i would like for him to gain during the course of the campaign though i am unsure how to go about it doing it mechanically.

As you know, the order of the Lycan is a werewolf subclass for the Blood Hunter and as a base, he would be considered a Beta werewolf in my setting. I would like for him to become an "Alpha Werewolf" the strongest, most powerful and the most lethal variety of Werewolf.

i was thinking about doing this like a magic item. Basically he attunes to this power, which grants him abilities that as he gains level (or more understanding of his power as game fluff) becomes better. I know you guys are alot smarter than me so i was hoping someone could help me out here. Thanks in advance.

Link to the Homebrew(s), please, so that we can properly know what we are starting with, mechanically. You then need to pin down the effective magic item rarity of the transition from "Beta" to "Alpha" so that we know how much to add.
