Essence ofShinza Bansho

You gain a free age and appearance change to whatever you want.

Your will is nigh-unbreakable. You can chat with impossibly charismatic individuals like Reinhard without bending the knee and resist all manner of mind-control and brainwashing.

You gain a peak human physique. It probably isn't gonna stay that way for long, considering what follows.

You are now a user of the Die Ewigkeit ritual/magic created by Mercurius, granting you a variety of abilities including (but not limited to) augmented physical ability and senses, detecting the supernatural, harming souls, and regeneration. You also grow stronger by devouring/absorbing souls, storing those souls inside yourself (the greater the amount and quality of such souls, the better).

You can hold an unlimited number of souls, and can also burn said souls as fuel for yourself.

You also have a Relic/Ahnenerbe, an artifact (or set of artifacts) bonded with your soul, which grows stronger as you do. You automatically absorb the souls of things you kill and also that which is killed by your Relic(s) even if not wielded by you.

You may also absorb nearby souls around you with some focus, such as ghosts. You start at the Assiah level (the very first, followed by Yetzirah, Briah, and finally Atziluth, at which point you become a God).

Your Relic/Ahnenerbe may be whatever you want. A sword, a spear, a motorcycle or an object you are fond of, etc. You may also import something you already own to be your Relic, such as, for example, the Necronomicon (and the Mecha attached to it). Relics can harm the soul and the supernatural, if they already couldn't before.

Once you reach the Briah level, you will develop a Creation Figment, giving you reality warping powers related to your inner desires (be it Hadou or Gudou type) and usually serves as an early indicator of what your Law may be as God. Be default this will be an original power as per above, but you may instead have a copy of a canon one (such as Reinhard Heydrich's Gladsheimr). Naturally, this will grow stronger the more and better souls you have.

But consuming souls isn't the only way you have to get stronger. Your soul has basically limitless potential, and can grow stronger via training, fighting, and meditation, such as with enough time and effort you could advance through the Die Ewigkeit levels without eating any souls. This also applies to other sorts of powers.

You may teach the Die Ewigkeit to others, if you want to.

You have access to the Power of Ego, allowing you to warp reality and defy the very Laws of the world with your willpower and accomplish things that shouldn't be possible. It can also enhance attributes such as offense, defense, speed, or regeneration, and even things like Commandments.

You have gained the Star Spirit Divine Blessing, one-use seals you can expend to gain benefits. The applications of this are boosting attack power (Saam), boosting defense (Kshatra), regeneration (Haoma), teleportation (Sewatir), flight (Fravard). Each of these applications costs one seal, and you may also multiple applications at once in different combinations, but such is risky. You start with 5 seals and can gain more based on military success and ability. Your seals replenish 24 hours after use.

You gain a Immutability, a concept and aspect of yourself that will not change even if the entire world/reality and everyone in it are inverted/switched/altered. You gain incredible talent regarding things related to your Immutability and gain a powerful ability based on it. Taking this Immutability to the very end can allow you to become a God, similar to the Die Ewigkeit's Atziluth level.

You have attained high skill in both the Sorcery of the Fourth Heaven and the Onmyōdō of the Sixth Heaven, allowing you to perform a variety of supernatural feats.

You have become a Krishna and gained an Avatara. Avatara is essentially a superpower unique to the user and could be any number of things, but healing seems mostly off the table. Avatara can be classified into Discretional (manually activated), Continuous (always active), or Conditional (activates on certain conditions) depending on their manner of activation, and into <Feeling Synchronization> or <Spatial> depending on how they affect the world. By default you'll essentially be rolling the gacha on what your Avatara will be like all other Krishnas, but you are guaranteed to have at least a decent ability and may instead have a copy of a canon one. You may also gain a Fifth Heaven Type Avatara, which is similar to the above but manifests as a suit of armor.

You gain an Equation that allows you to use Quintessence. Like Demons (Dust Angels), you don't need Satanael's permission to use this ability. Whether this Quintessence is positive or negative is up to you.

You have been granted the Tengan, vastly improving your insight, observation, and spellcasting abilities. You may close/open the third eye on your forehead as desired, appearing as if it wasn't there if closed. Active use of it requires it to be open.

You have gained access to Dream Magic / Kantan no Yume, allowing you to use your dreams for power. Kantan dreams are classified by type into Attack, Defense, Magic, Cancel, and Creation, each having two subdivisions. What types of Kantan you are good at depends on your personality. For example, using an attack type dream may boost your strength or speed. Kantan has 5 stages: Jodan (which you start at, allowing you to use a single dream at a time), Eidan (two dreams at once), Hadan (3 dreams at once, also allowing you to create your own unique dream in a manner kinda similar to Briah), Kyudan, and the final stage Tsuidan.

You have gained the Pantheon ability, becoming a Commander able to create Aeons based on your recollection. You recreate any individual you observe regardless of their powerlevel, with the better you understand them the stronger and closer to the original they are. You have no control over these Aeons beyond what you can enforce on them or convince them to do, aside from being able to dismiss/unsummon them at will. Fully recreated Aeons are a resurrection/continuation of the original and can't be dismissed. You may have multiple Aeons active, but only one of any given individual at a time.

You find yourself immune to and unaffected by Mithra's Good/Evil divide and similar, such as the Heavens of a Xianxia setting declaring it impossible to cultivate to a certain realm.

You are immune to the Amrita curse of immortality.

You have enormous potential to become a God, be it of the Hadou/Hegemony or Gudou/Transcendence types or even some weird mix of both. Of course, you may stop/lock yourself from becoming a God if you don't want to or find it a risk to yourself/reality/others.

You have a powerful stabilizing effect on reality, to the point you could have multiple allied Hadou Gods and their Laws coexist without problems.

Optionally, you have access to the Commandments of Mithra's Heaven. As a one-time effect you may take any number of Commandments you desire, each one imposing restrictions on you in exchange for benefits (usually related to the restrictions). The heavier the restrictions, the greater the benefits. There's a price to pay for breaking such Commandments though, death being fully possible depending on the Commandment. So basically a Geass, if you want to consider it what way. As a benefit probably unique to you, you may with some time and effort disable your Commandments, lifting their restrictions and shutting down their benefits until you reactivate them again (which takes about same time/effort as disabling them).

You may gain any Shinza Bansho or Senshinkan characters of your choice as your companions. By default you will quickly grow a bond with them. You may choose what relationships you will develop with each of these companions (being lovers, friends, etc.). If relevant (self-insert into their world, world merge, etc.), you are guaranteed to meet these companions in-universe, meeting them in positive circumstances (this resurrects companions dead by that point, which may draw attention).

Optionally, you may Self-Insert into Shinza Bansho (Dies Irae, Avesta of Black and White, etc.), Senshinkan, or a variant (fanfics, etc.). You may choose when, where, and what world. The specifics are up you; maybe you get dropped in (default), maybe you insert yourself into or replace a certain character, maybe you get reincarnated, maybe you get merged with a local counterpart of yourself, etc.
