People find catalysts all the time, yet what are they used for? They are used for Light and Regular Fortifications.
Catalysts give a certain percent chance of succeeding added to the chance you already have.
Catalysts add 1.25% for each one you use.
Here are the percentages:
Catalysts also increase the chance of the item becoming broken if failed.
Percentages are unknown as of yet.
You can find catalysts from certain quests.
