Simply adds Skyrim's built in soultrap spell effect to lightning bolt, chain lightning, and thunderbolt. Note that this increases the cost of these spells a small amount, which seems a fair trade in exchange for the additional functionality.

There may be some compatibility issues used in conjunction with any mod that alters the soultrap script. I use these spells in conjunction with Soultrap Redone, but have never been able to figure out how to get EnchSoultrapFFAimedArea to work seemlessly with it.
