G.M.s have the right to create and view the rules in their own games as see fit (Kevin's view).
That being said, if you go buy the standard rules. Old Ones are even more powerful then an Alien
Intelligences and the standard is 2D4+2 master psychic. Which means making a saving throw at
10. They come with +1D4 on all saving throws. There M.E. attribute is 10+4D6. So at a minimum
they get 14. That means a possible +1 to +12 to save vs. psionics. Now that's an alien
intelligence. Back in 1st edition, Old Ones had several thousand I.S.P. Yablix I believe had 30,000.
Did separate the psychic powers back then just major or minor. Still more than likely master
psychics. So would the catatonic strike work, in theory....
yes but very unrealistic. Kind of
like taking out one of the gods with a poison apple that puts them to sleep. Unrealistic but based
on game rules...possible
. Again you the G.M. make the world as you see fit. Just make
sure your players are aware of it and okay with it. Hey Carmen Bellaire had supernatural P.S.
ripping carpet of adhesion spells like their where tissue paper in his open house game. You pick up
a car and toss it and it did the same damage as a punch. So a 1000 lbs car thrown by a guy with
a P.S. of 20 did 1D4+5
. But it was Carmen's game and Carmen's rules. We kicked his
butt anyway.
