[edit] Introduction

Part of what is important to getting the best demon you can in Megami Tensei Online is merging demons together. There is a shop that lets you do this in most main towns, which should be easily found as you go there often for quests at the start of the game. In here you can (By yourself) Fuse 2 demons together, or if you are in a party, 3, with each party member donating a demon, however, only the party leader gets the end result.

[edit] Fusion

Generally, it is better to try to get the end result being on the same alignment as you (Law or Chaos) so the demon can be easily summoned.

When fusing, before the demon is made you will be shown its:

• Species
• Skill list
• Level
• Alignment

The result of the fusion is determined by two parameters : the race, and the level of the two demons you are fusing. Example :

• We will fuse a Level 11 天使(Tenshi/Divine) Angel and a Level 17 地霊 (Chirei/Earth Spirit) Sudama.
• According to the fusion chart, fusing a Divine with an Earth Spirit will produce a demon from the 夜魔(Yama/Night) race.
• To know wich demon from that race, take the average of the levels of the starting demons, round it down and add one.

(11+17)/2=14, 14+1=15

• No demons of the Night race has a level of 15. Therefore, we pick the next highest Night demon, Level 20 Night Lilim.

By fusing a Level 11 Angel and a Level 17 Sudama, we get a Level 20 Lilim.

Fusing two demons of the same family will always produce one of the four 精霊 (Seirei/Element) : Aeros, Earthies, Flamies or Aquans. When you fuse an Element with another demon, you will get either the next highest or the next lowest demon of the same family. For example, fusing a 妖精 (Yousei/Fairy) Jack Frost with an Aquans will produce a Jack o'lantern (rank up). On the other hand, fusing it with a Flamies will give you a Pixie (rank down).

[edit] Skill Inheritance

A demon obtained through fusion will inherit all of his "parents"' skills, provided he can use them (for example, a bird demon won't inherit bite-type skills). Inherited skills are not directly usable : the demon has to learn them first. In your demon's skill page, you should see a percentage underneath the skill icon. The skill will be learned once it reaches 100%. To raise the gauge, your demon must be hit by a skill of the same family than the one it is trying to learn. Simply put, heal your demon to make it learn healing skills, have him being hit by fire attacks to make it learn fire attacks, and so on.
