Getting -Para From Gelatinous Cube Corpse
There are very few sources of -para in ADOM; another one wouldn't go amiss.
90% of the time, the most dangerous status ailment in the game is Paralysis. Multiple creatures can give paralysis, including early game creatures (ghul deaths come to mind). Unlike poisoning and sickness, there is no way to cure paralysis, as until the -para wears off, you can do nothing except be paralyzed, attacked, potentially paralyzed again, et cetera.
At the moment, there are very few ways of gaining resistance from paralysis, and can *only* gain the intrinsic through pools. Thus, I'd like to suggest that Gelatinous Cube corpses be allowed to give -para when eaten (as well as the present effect of paralyzing the player temporarily). Cubes are uncommon, and at a 1% corpse drop rate (or maybe if you're kind raise it slightly, to a maximum of 5% like Blink Dogs), it's not going to be an easy way to get it, but it will offer just one more source for people to keep from fast RNG deaths, without making it as easy to get as, say, poison resistance.
