Prestige 2

Guiding the Lost - Through your time spent with Bella, and helping troubled souls move on to a better place, you have learnt to better soothe those lost in the dark. Your aura radiates with a warm, comforting feeling, washing over the souls of those around you. You may remove one effect or condition from any willing creature that starts their turn inside your aura. Additionally any souls within this aura may immediately be sent to your sanctuary in Bella's garden, and your charisma score and maximum increases by 2, and things that scale off your charisma modifier now scale off the score.

Sword of a Goddess - Your bond with your Seishin Katana has become unmatched, fully pouring your soul, spirit and emotions into the weapon, enhancing its abilities and connecting it to your own aura. The weapon no longer requires attunement, and can take on the form of any weapon you choose, allowing your soul to reimagine its appearance and store an amount of soul swords equal to your charisma score. Additionally before attacking with the weapon, you may expend 3 soul swords to form a spectral version of the weapon anywhere within your aura. You may make two attacks against any other creature within your aura with the weapon as though you were within 5ft of them before it disappears.

Prestige 4

Protection of the Soul - You have learnt to strengthen your soul, and empower it with the fierce protective loyalty rooted deep within a kitsune's blood. Creature's of your choice within your aura gain a bonus to their checks and armor class equal to the amount of soul swords you currently have, and cannot be affected by spells or affects that do not require a save, attack roll or check to take effect.

Ferocity of a Kitsune - Although you have devoted yourself to protecting the weak, and guiding those forsaken by Inari, the means to do so do not always come without harm. You understand that sometimes the only way to protect, is to defend with ferocity. You have learnt to channel the anger, confusion and despair of those you have saved into your own aura, empowering yourself and those around you. Creatures of your choice within your aura ignore resistances and immunities of creatures they attack. These creatures may also deal an additional amount of dice equal to the amount of soul swords you currently have, as you strengthen their resolve to fight and protect.

Prestige 6

Protector of the Forgotten - Although some were forgotten by Inari and shunned away, you would not forsake them as easily.

Your swords of light now deal 8d8 damage, and may be used to heal creatures within your aura for twice the amount instead of attacking.

Emotions of the Soul - You have learnt to control your emotions to a greater extent, allowing you to use all spiritual states at the same time. Additionally you may spend a charge of your channel divinity to empower your emotions, heightening their abilities for one hour. While empowered in this way, their dice and values of their effects are doubled. With your soul seeping into your aura and those around you, so do your emotions. Ikari now also activates when your allies within your aura take damage, and the benefits you receive from the Zen state applies to your allies as well.
