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 combinations for Thunder Magic.

Every Best Thunder Materia Fusion Combos¶

These are just some possible combinations to create the respective Materia. For example, place Fire in the first slot, and Blizzard in the second slot to obtain Thunder. Spells marked with “(M☆)” means that the spell 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.
