In Dragonborn Ascendant, I have things set up to read the Player's level and empower shouts accordingly. In setting that up, I determined that conditionals check the object that had the effect cast upon them. Since that wouldn't work for me, I set it to check the Player level.

In looking at some other spells in vanilla/DLC stuff, I saw that some used "target". Is that what is used to do condition checks on the spell's caster?
