Finding the spell that caused the magic effect

[tim57282]

Is there any way to find out which spell caused the active effect?

 

I'm currently dong something like this:

ScriptName script extends activemagiceffect
   SPELL Property SpellUsed Auto
   SpellUsed.GetEffectiveMagickaCost(akCaster)

But I have just realised that some MGEF's are caused my multiple spells, including staves and scrolls

This is a fairly large issue, with my current build of my mod breaking several staves and scrolls, and powers.

 

So, is there any way for the activemagiceffect to determine the spell which caused it?
