Moon Breathing Forms
There are a total of seven original forms that can be used with Moon Breathing, with the first form said to be the foundation for the rest of them.
First Form: Dark Moon
Before your attack, you may choose a target within 30 feet of you. You surge towards them, emanating a line 15ft wide between you and the target. All creatures take Lunar damage twice, and then you make an attack against your target.
Ascension:
Your movement during this Form does not provoke opportunity attacks.
Second Form: Moon Gazing
As an action, choose a target within melee range. Make 3 attacks against them with disadvantage, regardless of other circumstances. Once complete, cast magic missile on the target, which deals Radiant damage.
Ascension:
Waxing Moon: Your attacks against the target take into account other circumstances that may grant advantage.
Waning Moon: Each successful attack additionally casts Magic Missile whose damage type is Radiant.
Third Form: Moon Chains
After your attack action, stab your weapon into the ground, dealing Lunar damage within 5 feet of yourself twice.
Ascension:
The Lunar damage now hits creatures within 15 feet of you, and ignores creatures you designate.
Slayer Rank
As you explore the world and learn about new and interesting types of creatures, your expertise grows.
Whenever your Rank increases, you gain an Ability Score Improvement, in addition to the specific benefits of that rank and the ranks below.
1st Rank
-
At first rank, you gain the ability to cast Find Familiar once per day for no material cost and without expending a spell slot, however the only form it can take is that of a crow.

-
Upon reaching this rank, you can use an action to know the path to the strongest undead or fiend within 300 feet for the next ten minutes, even behind full cover, as long as there is a direct path to that creature. (A regular door wouldn’t block this feature, but a completely sealed vault door would). You may use this feature again after completing a long rest.

Your breathing ends and you cannot begin Breathing until your next turn.
