In the Dark Hunter book, Gatherer is describes as having a Rhotuka with a Mind Scrambling power, however the model does not have any Rhotuka launcher. Rather, it features a Kanoka launcher, which is not mentioned in the entry:
Another thing to note here is that mind scramble is written in italized, which is usually done for Kanoka powers.
During Gatherer’s appearance in NOGLB (which was written by a fan), he is also describes as using a Mind Scrambling Rhotuka, in addition to using Kanoka:
Was the Rhotuka erroneous, and rather intended to be a Kanoka of Mind Scrambling?
If yes, would he still possess Mind Scrambling Rhotuka in the story? Or would he instead have a Kanoka of Mind Scrambling, and would NOGLB be considered erroneous in this regard? (Which would in that case establish a new Kanoka power.)
If it is a Kanoka power, would the Kanohi forged from it be considered immoral?
Similar situation to Conjurer – Gatherer’s entry says he has a mind scramble Rhotuka. The model for Gatherer has no Rhotuka launchers at all, but he has a Kanoka disk launcher on his shoulder. I also noticed that mind scramble is italicized, and Kanoka powers always seem to be italicized while Rhotuka powers are not. Did you mean “Kanoka disk” when you wrote “Rhotuka spinner”? Probably
Not posting this as a definitive answer, but just additional information to take into consideration.
Also, as an addendum to this question: is Mind Scrambling the same as the Confusion Kraata power, and if not, what are the differences?
Well compared to the kraata confusion power and based on the description of Varian having been a victim of mind scrambling these powers seem to affect different parts of the mind. The confusion power works on memories or thoughts more such as trouble accessing information the victim has such as how to talk, use their powers, or where they are along with how they got there. While mind scrambling seems to focus more on processing information and especially sensation as Varian experienced a variety of colors at once which I assume is her trying to process her surroundings during that while also feeling agony. So to sum it up confusion is for thoughts and memories while mind scrambling is more for new information and sensations.
I can’t answer for Greg but considering most immoral Kanohi involve inflicting a negative and often distressing condition on an opponent disabling them in one way or another I say it is almost guaranteed that this Kanoka power would be an immoral Kanohi if it was made into one.
