In most RPG's (at least the ones I've played such as Persona 4, Final Fantasy 7, Dragon Warrior, Lunar, etc..) there are some enemies that are element-sensitive. They might take massive damage against some elements and no damage whatsoever against others.

The three types of arrows from Ocarina of Time were the initial inspiration for the Infuse spell. I liked how Link could change arrows depending on whatever enemy he was fighting. Although it's common for certain weapons to have an element attached to them (such as a flame sword) I didn't want to go that route if I could avoid it, largely because I wanted something a little different than the usual/normal way.
To solve this, I created the "Infusion" spell and attached it to a new weapon called the Elemental Bow. When Cecelia is equipped with it, the Infusion skill appears in her list of available magic. Once cast, the player is given the choice of which element to fuse her arrows with.
When an element is selected, the screen will flash the appropriate color for that element (blue for ice, red for fire, green for wind, yellow for lightning, and white for holy). A small icon will appear on screen to show what element is currently infused (see picture on right). Infusing another element will remove the effects of the previous one, thus the player can infuse only one element at a time.
