Reincarnation

Upon choosing an ending, the player will have the option to reincarnate in the ritual tab. Reincarnation resets all inventory (except sin), all area progress (excluding Astral World and Akashic Record) and their bonuses, everything within the ritual tab, everything within the routine tab (except equipment), history in story tab, and characters will leave your party. Everything else stays, including but not limited to, everything in the party tab (summons, skills, titles, research, etc), achievements, and shop items.

The first reincarnation will unlock Akashic Record.

Note: Reincarnating resets unpurchased advanced spells in Astral World from Antique Collector's Desert Lodging actions.

Endings
[To be filled in]

Willing Revenge
REQUIRES: Defeat Demon Empire Fort.

MINIMUM DESTINY NEEDED: 3.5k

You defeat the Demon King, only to discover that, thanks to the Revival Orb, he can't be defeated permanently.

A Moment of Peace
MINIMUM DESTINY NEEDED: 5.5k

The Demon King is defeated, but promises to return. You discover your mother locked away in a cell and free her, and take her back home to your home village. Why did the Demon King want to keep her alive...?

Hero of the Holy Sword
REQUIRES: First beat Tournament round 6. Talk with Lari and become her friend. Take over the Bandit Hideout afterwards. Similar to ending 2, you now need to reach the Smith Village and forge the Holy sword, but this time, you'll need to give it to Lari. Graduate and fight the Demon King like for ending 2, but this time let Lari make the Killing blow afterwards to unlock ending 3.

Minimum Destiny needed: 7k

TBD

The End of Revenge
REQUIRES: Don't Play with the girl. This will give you the option to Leave the Village alone. This will change many plot events. For example, as Norn isn't with you in Academic City where you can protect her, the Demons will attack your hometown in your absence and kidnap her, while killing your father along the way. In the Spirit Spring, you'll now find the Spirit Shrine where you'll have to get the powers of all Greater Elemental Spirits. This unlocks the Elemental Master title which you'll have to achieve before graduating and confronting the Demon King who can't withstand your root magic and is destroyed. Search the Labs to find a different End Boss this time and defeat it to unlock ending 4.

Minimum Destiny needed: 12K in the run before to choose it as your next chronicle.

TBD

Each Feeling
REQUIRES: [1M minimum status UP]

The difficulty for reaching this ending is very far from the previous 4 endings. You should have completed all 4 endings 5 times to get all of the bonus. After that, you should also beat all quests and get all summons. You should already have minimum of 13K status UP and got all status Up from unlocks.

After finishing the quests in evil city. You should have the followings before beating the tournament 9 & 10: (1) Dark Wave (2) Holy Light (3) Fully leveled up Characters, "You" which requires 47.8M level. (4) Summons from evil city. However 13K status UP can only merely finish tournament 9 & 10. You should have 1M minimum status UP (If you have summons from dragon village, the status UP can be lower.). 13K status UP is not possible to finish the ending 5.

The minimum magic attack should be ~1 Qi for all characters to finish this ending. When you have 1M status, you can easily beat tournament 9 & 10 easily without grinding magic attacks from Gluttony. You still need around 300x to 400x magic attacks bonus from Gluttony in order to beat the Demon king (ending 5). You also need unlock all equipment with magic attack bonus.

Many players finished this ending before the release of Dragon village. The suggestions above are workable without bonus form Dragon village. If you have the bonus from Dragon village and the "Dominator" from Astral World. You may not need 1M status UP.

Sin (resource)
Sins boost inspiration gain and DR talent multiplier, and can be acquired upon reincarnating. The sin multipliers are as follows:

The number of sins (as of version 1.5) is determined by the following formula:$$ \begin{align} \text{number of sins} =\ &\log_2\Bigl(\sum\frac{\text{experience acquired over all reincarnations}}{10M}\Bigr) \\ & \times \Bigl(1+ \frac{WarriorTalent - 1}{40}\Bigr) \\ & \times \Bigl(1+ \frac{SorcererTalent - 1}{40}\Bigr) \\ & \times \Bigl(1+ \frac{TamerTalent - 1}{40}\Bigr) \\ & \times \begin{cases} 1+ \frac{GluttonyMultiplier}{400} & \text{if }GluttonyMultiplier < 1000 \\ 1 + \frac{GluttonyMultiplier^{0.233}}{2} & \text{otherwise} \\ \end{cases} \\ & \times \begin{cases} 1+ \frac{GreedMultiplier}{400} & \text{if }GreedMultiplier < 1000 \\ 1 + \frac{GreedMultiplier^{0.233}}{2} & \text{otherwise} \\ \end{cases} \\ \end{align}$$

where log2 is the log function in base 2 and GreedMultiplier/GluttonyMultiplier are the multipliers shown at the top of the greed/gluttony routine screens respectively.

Sins strategy (speed runs/cap maximization)
The most important thing to note about grinding Sins is that it's based on EXP, with Greed and Gluttony playing the biggest roles; routine and quest multipliers are very minimal - even with the all classes active perk and 3.5million levels in all 15 routines after 3 days, they multiply by 1.04, three times. That's just a 1.125 multiplier; at the same time with roughly on par Greed/Gluttony/EXP taken together.

That gets you only ~11 sins for 3 days of time.

Alternatively, you can complete ED1 in 2 to 3 hours, maybe even cut that down to about an hour, and get 3-8 sins.

It's much more efficient to grind out a bunch of ED1s, than finish a longer Chronicle.

For involved grinding, I would suggest completing ED1, and maybe a few of ED2

If you've only completed ED1, you may not have enough max Destiny to leave Village alone - Norn is sweet and all, but she does make getting through Lostlorn Forest a lot slower; if you leave alone, you can just clear the dungeons and get straight to Academic City.

After that, your only goal is to clear titles until you can graduate. If you've completed ED1 and cleared a few of ED2, you shouldn't have a problem with destiny - use Hound Dog and donate, grind bosses for gold to eke out enough max destiny from dialogue.

The real trouble is Rank; you need 39 to graduate. Here, it's best to go with Warrior since they have a routine dedicated to Sacred Ritual, and the higher your habit efficiency, the better. Try grind down as big a gluttony and greed multiplier as reasonable before your first DR, as the higher talent will allow you to split your Habits between routines, Will, and basic SR multipliers.

It'll be likely that you'll go down some of the regular quest areas, and I'd advise that since there are a fair few dialogues that add buffs to Sacred Ritual.

Sins strategy (later in game)
Alternatively, Sins can be earned through drops by guardians (The Hermit and up) once you unlock envy after beating the 3rd guardian. The Hermit has a 1% base chance to drop 1 Sin, while the Arbitrator has a 0.2% base chance to drop 1.5 Sin, and the chance is multiplied by the number of days in that reincarnation (up to 10 before log3 diminishing returns) and the sin multiplier from exp that you normally get on reincarnation. As you can fight each guardian once an hour, this can become a good source for Sin with longer runs. After several days without reincarnating and a good sin multiplier from exp you can reach 100% chance from hermit and 20+% chance from arbitrator, letting you fill the current maximum of 28 sins every day, this is not as strong as late game reincarnations which can generate that in a bit over an hour, but its a lot more hands off.
