Wellspring

Wellspring, also dubbed as "Energy", is a material type introduced in . Energy materials contain the essences of spirit and strength combined, and are colored purple. In Kingdom Hearts, they are used as normal synthesis items, while in Kingdom Hearts II, they are "modifier" materials that can be added to a recipe of the same rank to halve the materials needed to make it, and are usable once the moogle reaches level 2, Novice Moogle. In Kingdom Hearts II, once all Energy materials are obtained the moogle will reward Sora with a Power Boost.

Design
Wellspring materials are represented by jewels with a Modifier material structure. They are purple and have jagged, cyan patterns resembling bolts of electricity and swirls of air in them, reflecting the two essences the material contains.

Both the English and Japanese names of this material reflect the electrical bolts in the jewels. "Surging" references power surges that lightning can cause. Lightning is a flow of electric energy.
