The mask Uloki formerly had was closer to the Mask of Clairvoyance in everyone's opinion, but sure, I can change it to the Mask of Analysis if you like.
Sorry, not at the moment. Yes to both of your questions, though.
I'll tell the RSG people.
Alright, I'll passs that on.
As far as I understand it all those "Matoran" names originate from the RSG people taking apart the Matoran language. Or rather, use what has been done in that regard so far. This means the Matoran mask names are translations of their power description and not just made up like they were before here.
From to scry - probably will enable the wearer to use reflecting surfaces like mirrors and gemstones to observe places were such surfaces exist, too. "Mask of Palantir", basically.
Encourages reckless behavior in those affected. Otherwise basically teh same reason teh Shelek is immoral, I guess.
Probably will/can only be used by Makuta anyway since it demands knowledge of viruses. Immoral because of direct association to Makuta/ viruses easily being able to cause problems, I guess.
Messing with someone's mind. Although to be fair the Komau probably is even worse.
Be aware that these are still old descriptions and will be altered, though.
The mask is still in discussion, so this is the old text. What it might or might not to do I can't safely say at this point.
Olisi shows alternate realities. Ersuloa is basically the Makuta power of Illusion - only less exhausting to use since it's a mask.
There was a discussion on RSG where most people were of the opinion that the Mask of Mutation should only be worn by Miserix. I personally don't think that's necessary, but if you can find something else that might fit Shornos in your opinion that sure would help resolve that issue.
