I was trying blue ring power in Abe's Oddysee today. Works everywhere, but it doesn't kill Scrabs, Paramites and static mudokons
. Sligs, bombs, slogs and chant suppressors are destroyed as usually. Didn't tried elum but I think he is unkillable too.
Edit:
@Lautaro
I would like to test your trainer, but mediafire or you deleted that file.
