Richter dont use luck code because... its richter character, not alucard. You can only input one code at a time, RICHTER is one of the three possible codes. (luck, axearmor, richter)
I suppose I will repeat it again, the reason to NOT use the luck code is the starting stats, they are determined by how you beat the prologue, with the very exception of luck code;
-if you use luck code, you start with 25hp and 1mp.
-if you use axearmor, or no code, you get the results of prologue, 70/75/80hp and 20/25/30 mp depending your performances (commonly refered as "normal")
-if you end with no hearts remaining you get heart refresh, if you end with cross you get neutron bomb.
edit: just to avoid confusion, there is no prologue with richter, of course, you start directly at the entrance.
the term "beat" I use in the description is the term used by the jp version of the game; in us version its call "kill".
The reason this matters for pacifist is because you need the mp to do spells, provided the objective is to avoid killing, you should not get extra mana from killing things; This is what happen in "low level" run; since it use the revenge glitch to trick the engine into thinking no murder was commited, you can only count on the starting mp you get from prologue, 30mp happen to be fine enough.
If you have 1mp you cannot transform into wolf or bat or anything, they drain mp over time.
The inherant HP increase influence "big toss", to get a big toss (used in several glitching techniques, or just for the speed itself) you require the damage taken to be 50% of your max hp, if you have 80hp you can only get big toss from a monster that deal you 40damage, or, 20 damage if you are under poison status (the shroom) that increase damage by 100%.
Needless to say; with 25HP you have a lot more oppertunity to do that compared to 80HP, it is the main reason most categories use luck code.
The axe armor here is used to stop the big toss before it send you to next room, voiding the room shift used to fall between walls.
As for the mention you technically cant move a pub into playground, I mean I cant do much about that, sorry to hear it.
How about you reject this for optimization and I slightly polish more the second castle, then you can put it in playground? just a though...
Regardless, I dont believe 3 branches should co-exist (hence my mention this should go playground in the sub), but, should there be more than one, "low level" would be the most logical to have, in which case I will promptly work into obsoleting it as well, should you decide to keep it, despite its inferior in term of "pacifism" since it actually kill 5 and "luck code" current kills 3.
I also agree that luck code mention is redundant provided almost all movies uses that, I cant promise new movies will not use "normal mode" tho.
I suppose "Replay mode" is more important mention; this basicly mean sram usage, when you finish the game, any new save will have "REPLAY" in its description (and when finish its "CLEAR"), in all movies this is used to buy duplicator and skip cutscenes.
I would like to mention also the "no major skip glitch" is a farce; plently of major skip glitch are used in the movie that doesnt use sram.
Skiping richter is done in a specific way to avoid its dialog (otherwise with sram its faster and you just skip the cutscene), and its definitly a massive skip.
If you want me to clean up some tags related to the several branches we have, I will need the wiki edit role I suppose.
