== Accuracy reduction in Generation II ==

(Relevant code is [https://github.com/pret/pokecrystal/blob/d0d61cb3ab847ff0c72a840363b89d4acf05b5f5/battle/effect_commands.asm#L1729 here].) [[Accuracy|Move accuracy]] in this Generation should be out of [0,255] (not [0,100]); for simplicity reasons, we seem to never mention that anywhere. They start off with that value (e.g. 255 for Pound), then incorporate stat stages (let's say it's -1 accuracy, so it'll end up 255*75/100=191). Then, BrightPowder just '''subtracts''' 20 (191-20=171). A random number [0,255] is compared to that number, and if it's greater or equal, it'll be a miss (85/256~=33.2% in the example).

The wording from when this was created was just plainly wrong&mdash;the "penalty" didn't decrease "from 20% to 10%"; it was additive, then became multiplicative. However, the original wording from [[In-battle effect item]] was apparently unclear, and it may also be misleading (due to it being out of 256); I tried to reword it, but if anyone is able to word it any clearer, it'd be much appreciated.

TL;DR: BrightPowder is additive in Generation II, and reduces accuracy by 20/256 no matter the move/stat stages. [[User:Nescientist|Nescientist]] ([[User talk:Nescientist|talk]]) 17:55, 14 July 2017 (UTC)
