Kruin and Inquisitors, questions Options

[Kerkes]

well, I must say I'm a bit surprised nobody asks help about this one.. (in my latest run, it was the hardest battle for sure. 17 reloads! AAAAAArrrrggh!)
The thing I wanted to ask is this:
Is Kruin immune to "dispel magic" cast from an Inquisitor?
I once played the game with a custom Inq in party (was lvl 18 by the time I met Kruin, I did some of WK, Umar Witch etc.before going back to Alkathla from Underdark). As soon as his buffs kick in, Inq fires his dispel. I get a message : spell ineffective?!
Now, I quit inquisitors for good, and took a blade instead, which, I must say, are 10 times more useful than an Inquisitor will ever be (if you want a powerful dispeller, that is) regardless of his Avenger sword.
Same battle, blade is lvl 23.
Took 4 reloads, and it worked ("remove magic" was succesful.)
What's up with that?

Just checked again and noticed that unlike other dispel magic spells, the inquisitor's dispel magic didn't have that bug even in the vanilla game. Then checked it in v5 and can confirm that it doesn't have that bug in v5 either.

In other words, the message "Spell ineffective" you have seen has had nothing to do with your inquisitor's spell. Probably you had cast some other spell on him and the message was related to that other spell.
