Devil's Tree

== Overview ==
As you progress through a card's Devil's Tree, you can improve that card's attributes, raise its maximum level, earn items, etc.
In order to progress, you will need specific items. These items can be earned by completing To Do missions and by clearing either battle stages in Obey Me! or Ruri★Tunes rhythm stages in Nightbringer.
Only by unlocking all of the spaces in a card's normal and secret Devil's Tree can you unlock a card's full potential and reach 100% progress for a card.
== Types of Spaces ==
The following types of spaces appear in Devil's Tree:
=== Attribute Spaces ===
( Pride, Greed, Envy, Wrath, Lust, Gluttony, Sloth) Up
=== Reward Spaces ===
==== Obey Me! ====
==== Nightbringer ====
== Unlocking Spaces ==
Unlocking a space requires Grimm and specific items, as seen in the table below. Spaces must be unlocked in order. Branching paths may require that more than one space be unlocked to proceed.
In Nightbringer, it became possible on February 15, 2024 to unlock multiple Devil's Tree spaces at once if you own the necessary items and Grimm.
=== Items Required to Unlock Spaces ===
The items required to unlock spaces come in the following seven different attributes: Pride, Greed, Envy, Wrath, Lust, Gluttony, and Sloth. These items can be obtained from Lessons as well as Pop Quizzes, Otaku Boot Camp, and unlocking Devil's Tree item spaces.
