Breathing
As a bonus action, you can enter your Breathing state for ten minutes if you aren't wearing heavy armor. You may do this a number of times per long rest equal to your Constitution modifier. You may also use a bonus action to end your Breathing.
While Breathing, you can use a number of Forms equal to your proficiency bonus with a melee Finesse weapon of your choice. You may expend another use of your Breathing as a bonus action to refresh your Breathing. Refreshing your Breathing allows you to once again use a number of Forms equal to your proficiency bonus, however, it does not "roll over" unspent Forms from the previous Breathing.
In the event a target has to make a Saving Throw against one of your Breathing abilities, the DC is equal to 8 + your proficiency bonus + your Constitution modifier
Flame 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: Unknown Flame
As an attack, move up to half your speed towards a creature and attack them, dealing additional Flame damage on hit.
Ascension:
The creature must make a Constitution Saving Throw or fall prone.
Second Form: Scorching Sun
Before attacking, you may use this Form to increase your Critical Range by 1 until your next successful attack.
Ascension:
Your critical range will remain increased until you critically strike.
Third Form: Flaming Universe
Make a melee attack against a creature, dealing additional Flame damage twice.
Ascension:
When you critically strike using this Form, you deal triple damage instead of double.
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.
-
Additionally, while Breathing, you have advantage on checks made to recall information about fiends and undead. Finally, you have advantage on checks made to track fiends and undead you are aware of.
2nd Rank
-
You gain the Extra Attack feature, as is outlined in every other martial class page.
-
You gain proficiency in Performance. If you already have proficiency in this skill, you instead gain Expertise.
3rd Rank
-
You gain a climbing speed equal to your walking speed.
-
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.
4th Rank
-
You gain resistance to poison damage, and advantage on saving throws made against poison. In addition, whenever you make a saving throw against poison, you become aware of the fact that you are being poisoned, and the type of contact that caused the poison.
-
When you expend one or more hit dice during a short rest, you may choose to expend one use of your Breathing to add your Constitution modifier to each die a second time.
5th Rank
-
At the start of each of your turns while Breathing, you gain temporary hit points equal to your Lunar dice plus your Constitution modifier.
-
You are immune to poison while Breathing.
-
You have advantage on saving throws caused by fiends and undead as long as you are not surprised.
Fourth Form: Blooming Flame
When attacked by a creature within your melee range, you may use a reaction to increase your AC by 5 for that attack. If this causes the attack to miss, you deal Flame damage to them three times.
Ascension:
This no longer consumes your Reaction.
Fifth Form: Flame Tiger
As a full round action, target a creature within melee range. Make five attacks against that creature, dealing additional Flame damage with each successful attack. Your Breathing then ends, and you cannot Breathe again until your next turn.
Ascension:
If all of your attacks from this Form are successful, you take on the aspect of the tiger, dealing additional Flame damage with each attack for the next minute (This effect does not stack).
Sixth Form: Ren-Goku
As a full round action, choose a target within twice your maximum Speed away from you that is within line of sight. You take the shortest available path to that creature, and make a melee attack against them using First Form: Unknown Flame. If the attack is successful, repeat this process choosing a different target than the last until you fail an attack. The movement made as part of this Form does not provoke attacks of opportunity.
Seventh Form: Black Flames
As a bonus action, activate this Form and choose a target to be your Nemesis. Your Form is active for 1 minute or until your Nemesis is reduced to 0 hit points. While this Form is active, your Flame damage is doubled
