Fusion (Digital Devil Story: Megami Tensei II)

This page details the process of fusion in Digital Devil Story: Megami Tensei II.

Fusion Basics

Fusion can be performed at the Manor of Heresy, which appears in various towns. Using the 2x Fusion option, Hero can combine two demons to create a new one. In certain towns, a 3x Fusion option is also available, though it is limited to demons of the Good alignment. Before a demon can be used in fusion, it must first be revived. Hero cannot fuse demons that are in the active party or whose level exceeds his own.
