When you unlock Materia Fusion in Crisis Core Reunion, you’ll soon realize that the game doesn’t really restrict you when combining Materia. Although this is a good thing, it can lead to some really strong combinations, some which can outright break the difficulty of the game. Thankfully, this page will list some of the strongest fusion combinations for the Ultimate Materia.

All Ultimate Materia Fusion Combos¶

These are just some possible combinations to create the respective Materia. For example, place a mastered Electrocute in the first slot, and Libra in the second slot to obtain Energy. Spells marked with “(M☆)” means that the materia needs to be a fully upgraded Master Rank version of the spell. If there is only one “(M☆)” in the list, either of them can be a Master Rank. When you see “Any DMW”, this means use any materia which impacts the DMW like Rush Assault.
