Ok, so let me get this straight. If I want to go for a special ending and say I start lawful, I need to make sure I don't get crowned but become chaotic first otherwise Baab Gaab the witch won't give me the first two quests - which happen to be the hardest ones IIRC (giant boar skull and scroll of danger?), as well as feeding the demented ratling (as he won't react unless the PC is chaotic.. right?). Ok, done. But THEN, much later in the game, once I reach level 45 only I am able to talk to the Assassin Prince, go to the infinite dungeon to kill Filk.. and then have to get back to lawful or neutral otherwise the mad ministrel won't give me access to the scintillating cave? That's incredibly hard. Say then I want to go for Avatar of Chaos or whatever it is called; that means that I have to become chaotic AGAIN after that, is it? Is this all correct or am I missing something? All those allignment changes seem to be unavoidable for ultra endings and absolutely a pain. Also, on top of this, when should I get crowned? and would I need to be at extreme alignment (L+, N=, C-)?

TL; DR:
Does going for ultra-ending necessarily requires to be C to satisfy the first two Gaab Baay's quest and the Demented Ratling quest, and THEN be L or N at level 45 to get the tip from the Mad Ministrel?
If so, when in this process is a good time to be crowned, and would that require extreme alignment?

Also, two other questions:
A) In Adom's most recent version, does reducing attributes below zero kill the PC? If not, does it lowers the stats potentials?
B) Could it be that I randomly found the Crumpled Scroll in early-mid part of the game, or can it be only obtained from the Emperor Moloch in the Scintillating Cave?
