...is Paralyzation, a 3rd level illusionist spell in AD&D 1st edition. It affects a number of creatures equal to twice the caster's experience level (so at least ten) and allows a saving throw. Those who do not save are paralyzed. According to the book, the only ways to undo this paralysis are the use of dispel magic, dispel illusion, or willful dismissal of the spell by the caster. The duration is listed as "Special." In OSRIC, the duration is listed as "Permanent."
I find that, as a DM, I am a bit troubled by a third level spell having the ability to permanently paralyze a creature. On one hand, the players in AD&D 1st edition have enough stacked against them as it is; think of all the monsters with instant kill type attacks. On the other hand, paralysis in AD&D is, in all other cases I can think of, temporary, even if the duration is for a long damn time.
I'm thinking about limiting the duration of the paralysis to 3d4 turns, making it comparable to that of a ghoul's touch. This still makes the spell a death sentence to anyone the PCs want dead, so I doubt they will complain very much. If I do this, I might remove the caster's option to end it at will.
Anyone else have any thoughts on this?
