@Akr a lot of your post is either agreeing with with me or answering the questions I asked.
"So it's in character for Ainz to use TGOALID if nothing else works?"
Yes.
Nothing wrong I just asked a question and you answered.
" I don't think you're interpreting SBA correctly. This is not a fight to the death. It says that if a character has to, they will kill."
If an enemy is strong enough to be on his level, he almost always goes to kill them period. Immediately tries to kill.
I didn't say what Ainz wouldn't or would do that all I did in that specific part was restate a part of SBA.
"My argument was that if Ainz wouldn't fight someone that ignores all of his attacks and becomes stronger by eating them, instead of revealing his trump card."
Except he wouldn't. Ainz would teleport away, apply a crap ton of buffs, come back, and The Goal of All Life is Death his ass.
Again I don't know what I said was wrong here. I specifically say IF he wouldn't so I'm implying he wouldn't do that and you agree with me by saying he wouldn't so I don't know why you put an except when what you said was the same as what I said.
"fighting someone who could ignore immunity to death magic."
Citation please. Magic resistance does not equate to Death Manipulation.
Right before this I say that Acno would become stronger and learn his magics by eating Ainz's normal magics and that Ainz does not know if Acno would be able to eat Ainz's TGOALID and learn that ability which is where the part you qouted comes from.
"How the fight would go in this scenario is Acno BFRs Ainz to the human world, "
Would never happen since Ainz would never let Acnologia get a hit in since he's a dragon; Dragons in Yggdrassil, even ones the size of small rooms, can be anywhere between level 90 to max level. Because Acnologia is a large dragon, he'd immediately take him seriously.
Acno doesn't need to hit Ainz to BFR him, his BFR is ranged and isn't dodgeable.
"Ainz teleports somewhere else to learn about Acno and Acno wins since Ainz left"
That's not how that works dude. BFR only works in a specific amount of time; here I'll even quote it from the SBA Page. "removing the opponent from the battlefield for at least one week (
BFR)", so Ainz teleporting away for like 2 days will not make him lose at all.
Again I'm not sure if I made this clear enough but multiple times I put an IF and I was using that to imply that I don't know what Ainz would or how long he would be gone in character.
"If it is in his nature to blindly throw all of his attacks at an enemy that would visibly make the enemy stronger and then throw his ultimate move at the enemy ignoring that he doesn't know if this will also make the enemy stronger, then yeah Ainz would win this."
Your argument is completely banking on the fact that Ainz teleporting away = instant loss when it isn't. Ainz can literally spend 3 days preparing far away from Acnologia and come back and he'd still won't BFR-Lose. Also, he doesn't need to use his ultimate move as Acnologia doesn't resist any of Ainz's other Death Manipulation spells. Magic Resistance =/= Death Resistance.
See above for why I wouldn't know it only takes Ainz 3 days to prepare for unknown enemies. Again I didn't say it was Acno's BFR for why Ainz would lose but that Ainz himself would leave and learn more about the enemy. He would need to use his ultimate move as TGOALID is the only spell that ignores immunity to death magic. You said it yourself Death Manipulation "Spells". Acno would completely be able to ignore any normal death manip spells as he is immune to magic. If you argue that is NLF, not only is there Death Magic in Fairy Tail but Zeref is a genius with it and he still doesn't think he can beat Acno in a fight. If any of Zeref's attacks could just kill Acno on touch then Zeref wouldn't have spent years making an army to fight him.
