Well, I have an issue with Innershade and its main quest: I can't hurt 9XE1.

Reproducable behaviour:

Watch out for the second half of the video; it is the second run... first run was with the interjection of Gahesh, so I avoided this in the second approach to minimize possible influence.

The quest variable is 4. Therefore the creature should be 9XE1. The actions of 9XE1 follow the script (protection spells, magic missile, ice storm). I hit the creature because I can see/read the slow effect from Brages weapon. But no damage at all even with critical hits. The creature itself should only have 60% resistance (regarding NI). I even don't get the message like: 0 damage or so. The only effect on the creature (in the file) is a blur effect. 

Via CLUA I created another 9XE1 which shows the same problems. 9XE2 somehow disappeared and 9XE3 I was able to kill. As they are all using the same script and dlg of course the game can't handle them all. 

Well I have no idea why 9XE1 has this kind of immunity. 

A direct comparison of 9XE1 vs  9XE3:

only the differences
HP:  130 vs 90 
Animation: static_boy vs ghast
Class: wraith vs spectre
Script name: 9XE1 vs 9XE3
Everything else is the same.

edit: 
I played a bit with 9XE1: statistics with magic missiles: roughly 60% trigger a message of magic resistance and no effect for the other projectils. Therefore resistances seems to work.
