Requesting high leveled evan vids

I'm just taking a stab on what the x-value is in Fiel's extraction. Taking a look at what it's used for in the other skills, it can either mean +5 power, or +5% power. +5% would make more sense since it would be more like a Corsair's Homing. Also looking at the video, her Illusion damage went up about 1-2k after Ghost Lettering, which means it has to be a higher increase than +5 power.
