Homebrew Werewolf Species Details

Obviously, becoming a Lycanthrope turns you into a werebeast. Whilst the easiest way is to be bitten by a werebeast and survive, there's also a druidic ritual called the Lunar Sacrament that can curse a victim with this transformation, which is obviously viewed in a holy perspective by druids. 
Mechanically, taking this Transformation requires 13 Strength, and its Save DC keys off of Strength. The following are possible level milestones for the Lycanthrope:

Establishing a pack of lycanthropes.

Killing an alpha lycanthrope.

Gaining control of your animalistic urges.

Unleashing the beast within and losing your humanity.

At 1st level, you gain the Boons Hybrid Transformation (you can change into a half-humanoid, half-beast shape) and Shapechanger's Form (+2 Strength, +1 Constitution, gain the Shapechanger type), and you receive the Flaw Lust for the Hunt. This flaw forces you to make a DC 10 Wisdom save at the start of each turn, or move towards the nearest NPC, prioritizing the helpless, so you can try to kill it; when exposed to a full moon's light, you automatically fail this save. The first time you see a full moon, you need to pass a DC 20 Wisdom save or be forcibly transformed into hybrid shape until dawn.

At 2nd level, you can take the Boons Iron Pelt (gain resistance to physical damage from non-silver and non-magical sources in hybrid form), Hunter's Howl (you can use a howl to mark a creature as prey, gaining bonuses to tracking and killing it) or Kindred Form (you can now assume animal form as well as hybrid form), and you receive the Flaw Silver Sensitivity. This makes you Vulnerable to damage done by silvered weapons when you're in hybrid or kindred form, and you cannot apply any Resistance to an attack made by a silvered weapon.

At 3rd level, you can take the Boons Titanic Vigor (+2 max HP per level, gain 5 temp HP each turn in hybrid form), Predatory Leap (double jumping distance, can make pounce attacks in hybrid form) or Bestial Savagery (hybrid form gains: attacks are damage-buffed and count as magic, +1 AC, immunity to charm & fear), and you receive the Flaw Fraying Memories. This flaw gives you Disadvantage on Intelligence ability and skill checks based on recalling information or knowledge.

At 4th level, you can take the Boons Savage Instincts (hybrid form attacks are suped up vs. hurt targets), Kindred Affinity (requires Kindred Form, lets you speak and cast spells in kindred form) or Unstoppable Rage (you can keep fighting at 0 HP), and you receive the Flaw Predatory Nature. This flaw makes it harder to resist your urge to kill the weak and helpless, as well as making it harder to return to your original form.
