Sin Infusion

Overview

Essence of Sin

Sin Infusion is similar to Mitama Infusion, except that it's much simpler.

• Sin Infusion is available on the Mitama menu.
• To perform a Sin Infusion, it's necessary to gather Essence of Sin, a material obtained as reward for playing Tokyo Abyss monthly quest.
• There is only one kind of Essence of Sin, which can be applied to increase any basic stat of a Demon (Strength, Magic, Vitality, Agility, Luck).
• A Demon must be awakened to receive a Sin Infusion.

The maximum Infusions a Demon may receive depends on its grade:

Demon Grade	Maximum Infusions	Essence/Increase
1★	240	1
2★	240	1
3★	160	2
4★	80	12
5★	80	16

Because 2★ and 5★ Demons are, generally, better and have the same maximum Sin Infusion limits as 1★ and 4★ Demons, respectively, the former would end up stronger than the latter after getting fully infused. The cut is not so clear regarding 3★ Demons (their limit is twice of 4★, but they are, usually, much weaker than them, mainly when it comes to Skills).

It's important to note how unbalanced is the cost per point increased. 1★ and 2★ Demons require just one Essence of Sin to increase any Stat, while 4★ require 12. Considering those costs, Infusing 5★ Demons is proportionally cheaper than 4★.

Anyway, because Essence of Sin is a very time consuming item to gather (there's no Auto Move to run the Tokyo Abyss automatically, and it only resets the rewards once per month), it's better to spend it only on the best Demons, and only on those that will actually be used.
